+
+### OBP API Configuration
+
+The multi-provider system fetches available providers from:
+```
+GET /obp/v5.1.0/well-known
+```
+
+**Expected Response:**
+```json
+{
+  "well_known_uris": [
+    {
+      "provider": "obp-oidc",
+      "url": "http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration"
+    },
+    {
+      "provider": "keycloak",
+      "url": "http://127.0.0.1:8180/realms/obp/.well-known/openid-configuration"
+    }
+  ]
+}
+```
+
+---
+
+## Endpoints
+
+### New Endpoints
+
+| Method | Path | Description |
+|--------|------|-------------|
+| GET | `/api/oauth2/providers` | List available OIDC providers with status |
+
+### Updated Endpoints
+
+| Method | Path | Query Parameters | Description |
+|--------|------|------------------|-------------|
+| GET | `/api/oauth2/connect` | `provider` (optional), `redirect` (optional) | Initiate OAuth2 flow with selected provider |
+| GET | `/api/oauth2/callback` | `code`, `state`, `error` (optional) | Handle OAuth2 callback from any provider |
+
+---
+
+## Session Data
+
+### Login Initiation
+```javascript
+session = {
+  oauth2_provider: "obp-oidc",           // Provider name
+  oauth2_code_verifier: "...",           // PKCE code verifier
+  oauth2_state: "...",                   // CSRF state token
+  oauth2_redirect_page: "/resource-docs" // Redirect after auth
+}
+```
+
+### After Token Exchange
+```javascript
+session = {
+  oauth2_provider: "obp-oidc",      // Provider used
+  oauth2_access_token: "...",       // Access token
+  oauth2_refresh_token: "...",      // Refresh token
+  oauth2_id_token: "...",           // ID token (JWT)
+  user: {
+    username: "john.doe",
+    email: "john@example.com",
+    name: "John Doe",
+    provider: "obp-oidc",
+    sub: "uuid-1234"
+  }
+}
+```
+
+---
+
+## Backward Compatibility
+
+The implementation maintains full backward compatibility with the existing single-provider OAuth2 system:
+
+1. **Legacy Environment Variable**: `VITE_OBP_OAUTH2_WELL_KNOWN_URL` still works
+2. **Fallback Behavior**: If no provider parameter is specified, falls back to legacy OAuth2Service
+3. **No Breaking Changes**: Existing deployments continue to work without changes
+4. **Gradual Migration**: Can enable multi-provider incrementally
+
+---
+
+## Benefits
+
+1. ✅ **User Choice** - Users select their preferred identity provider
+2. ✅ **Dynamic Discovery** - Providers discovered from OBP API automatically
+3. ✅ **Health Monitoring** - Real-time provider availability tracking
+4. ✅ **Extensibility** - Add new providers via environment variables only
+5. ✅ **Resilience** - Fallback to available providers if one fails
+6. ✅ **Backward Compatible** - No breaking changes for existing deployments
+
+---
+
+## Next Steps
+
+### Priority 1: Frontend Implementation
+1. Update `HeaderNav.vue` to fetch and display available providers
+2. Create `ProviderSelector.vue` component for provider selection
+3. Test login flow with multiple providers
+4. Handle error states gracefully
+
+### Priority 2: Testing
+1. Write unit tests for all new services
+2. Create integration tests for multi-provider flow
+3. Add E2E tests for login scenarios
+
+### Priority 3: Documentation
+1. Update README.md with setup instructions
+2. Document environment variables for each provider
+3. Create migration guide from single to multi-provider
+4. Update deployment documentation

+# Multi-OIDC Provider Implementation - Executive Summary
+
+## Overview
+
+This document provides a high-level summary of implementing multiple OIDC provider support in API Explorer II, based on the proven architecture from OBP-Portal.
+
+---
+
+## Current State
+
+**API Explorer II** currently supports OAuth2/OIDC authentication with a **single provider** configured via environment variables:
+
+```bash
+VITE_OBP_OAUTH2_WELL_KNOWN_URL=http://localhost:9000/obp-oidc/.well-known/openid-configuration
+VITE_OBP_OAUTH2_CLIENT_ID=<client-id>
+VITE_OBP_OAUTH2_CLIENT_SECRET=<client-secret>
+```
+
+**Limitations:**
+- Only one OIDC provider supported at a time
+- No user choice of authentication method
+- Requires redeployment to switch providers
+- No fallback if provider is unavailable
+
+---
+
+## Target State
+
+**Multi-Provider Support** allows users to choose from multiple identity providers at login:
+
+- **OBP-OIDC** - Open Bank Project's identity provider
+- **Keycloak** - Enterprise identity management
+- **Google** - Consumer identity (optional)
+- **GitHub** - Developer identity (optional)
+- **Custom** - Any OpenID Connect provider
+
+---
+
+## How OBP-Portal Does It
+
+### 1. Dynamic Provider Discovery
+
+OBP-Portal fetches available OIDC providers from the **OBP API**:
+
+```
+GET /obp/v5.1.0/well-known
+```
+
+**Response:**
+```json
+{
+  "well_known_uris": [
+    {
+      "provider": "obp-oidc",
+      "url": "http://localhost:9000/obp-oidc/.well-known/openid-configuration"
+    },
+    {
+      "provider": "keycloak",
+      "url": "http://localhost:8180/realms/obp/.well-known/openid-configuration"
+    }
+  ]
+}
+```
+
+### 2. Provider Manager
+
+**Key Component:** `OAuth2ProviderManager`
+
+**Responsibilities:**
+- Fetch well-known URIs from OBP API
+- Initialize OAuth2 client for each provider
+- Track provider health (available/unavailable)
+- Perform periodic health checks (60s intervals)
+- Provide access to specific providers
+
+### 3. Provider Factory
+
+**Key Component:** `OAuth2ProviderFactory`
+
+**Responsibilities:**
+- Strategy pattern for provider-specific configuration
+- Load credentials from environment variables
+- Create OAuth2 clients with OIDC discovery
+- Support multiple provider types
+
+**Strategy Pattern:**
+```typescript
+strategies.set('obp-oidc', {
+  clientId: process.env.VITE_OBP_OAUTH2_CLIENT_ID,
+  clientSecret: process.env.VITE_OBP_OAUTH2_CLIENT_SECRET,
+  redirectUri: process.env.VITE_OBP_OAUTH2_REDIRECT_URL
+})
+
+strategies.set('keycloak', {
+  clientId: process.env.VITE_KEYCLOAK_CLIENT_ID,
+  clientSecret: process.env.VITE_KEYCLOAK_CLIENT_SECRET,
+  redirectUri: process.env.VITE_KEYCLOAK_REDIRECT_URL
+})
+```
+
+### 4. User Flow
+
+```
+1. User clicks "Login" 
+   → Shows provider selection dialog
+
+2. User selects provider (e.g., "OBP-OIDC")
+   → GET /api/oauth2/connect?provider=obp-oidc
+
+3. Server:
+   - Retrieves OAuth2 client for "obp-oidc"
+   - Generates PKCE parameters
+   - Stores provider name in session
+   - Redirects to provider's authorization endpoint
+
+4. User authenticates on selected OIDC provider
+
+5. Provider redirects back:
+   → GET /api/oauth2/callback?code=xxx&state=yyy
+
+6. Server:
+   - Retrieves provider from session ("obp-oidc")
+   - Gets corresponding OAuth2 client
+   - Exchanges code for tokens
+   - Stores tokens with provider name
+
+7. User authenticated with selected provider
+```
+
+---
+
+## Implementation Architecture for API Explorer II
+
+### New Services
+
+#### 1. **OAuth2ClientWithConfig** (extends `OAuth2Client` from arctic)
+```typescript
+class OAuth2ClientWithConfig extends OAuth2Client {
+  public OIDCConfig?: OIDCConfiguration
+  public provider: string
+  
+  async initOIDCConfig(oidcConfigUrl: string): Promise<void>
+  getAuthorizationEndpoint(): string
+  getTokenEndpoint(): string
+  getUserInfoEndpoint(): string
+}
+```
+
+#### 2. **OAuth2ProviderFactory**
+```typescript
+class OAuth2ProviderFactory {
+  private strategies: Map<string, ProviderStrategy>
+  
+  async initializeProvider(wellKnownUri: WellKnownUri): Promise<OAuth2ClientWithConfig>
+  getConfiguredProviders(): string[]
+}
+```
+
+#### 3. **OAuth2ProviderManager**
+```typescript
+class OAuth2ProviderManager {
+  private providers: Map<string, OAuth2ClientWithConfig>
+  
+  async fetchWellKnownUris(): Promise<WellKnownUri[]>
+  async initializeProviders(): Promise<boolean>
+  getProvider(providerName: string): OAuth2ClientWithConfig
+  getAvailableProviders(): string[]
+  startHealthCheck(intervalMs: number): void
+}
+```
+
+### Updated Controllers
+
+#### 1. **OAuth2ProvidersController** (NEW)
+```typescript
+GET /api/oauth2/providers
+→ Returns: { providers: [...], count: 2, availableCount: 1 }
+```
+
+#### 2. **OAuth2ConnectController** (UPDATED)
+```typescript
+GET /api/oauth2/connect?provider=obp-oidc&redirect=/resource-docs
+→ Redirects to selected provider's authorization endpoint
+```
+
+#### 3. **OAuth2CallbackController** (UPDATED)
+```typescript
+GET /api/oauth2/callback?code=xxx&state=yyy
+→ Uses provider from session to exchange code for tokens
+```
+
+### Frontend Updates
+
+#### **HeaderNav.vue** (UPDATED)
+
+**Before:**
+```vue
+<a href="/api/oauth2/connect">Login</a>
+```
+
+**After:**
+```vue
+<button @click="handleLoginClick">
+  Login 
+  <span v-if="availableProviders.length > 1">▼</span>
+</button>
+
+<!-- Provider Selection Dialog -->
+<el-dialog v-model="showProviderSelector">
+  <div v-for="provider in availableProviders">
+    <div @click="loginWithProvider(provider.name)">
+      {{ provider.name }}
+    </div>
+  </div>
+</el-dialog>
+```
+
+---
+
+## Configuration
+
+### Environment Variables
+
+```bash
+# OBP-OIDC Provider
+VITE_OBP_OAUTH2_CLIENT_ID=48ac28e9-9ee3-47fd-8448-69a62764b779
+VITE_OBP_OAUTH2_CLIENT_SECRET=fOTQF7jfg8C74u7ZhSjVQpoBYvD0KpWfM5UsEZBSFFM
+VITE_OBP_OAUTH2_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
+
+# Keycloak Provider
+VITE_KEYCLOAK_CLIENT_ID=obp-api-explorer
+VITE_KEYCLOAK_CLIENT_SECRET=your-keycloak-secret
+VITE_KEYCLOAK_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
+
+# Google Provider (Optional)
+VITE_GOOGLE_CLIENT_ID=your-google-client-id
+VITE_GOOGLE_CLIENT_SECRET=your-google-client-secret
+VITE_GOOGLE_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
+```
+
+**Note:** No need to specify well-known URLs - they are fetched from OBP API!
+
+---
+
+## Key Benefits
+
+### 1. **Dynamic Discovery**
+- Providers are discovered from OBP API at runtime
+- No hardcoded provider list
+- Easy to add new providers without code changes
+

+# Multi-OIDC Provider Testing Guide
+
+**Branch:** `multi-login`  
+**Date:** 2024  
+**Status:** Ready for Testing
+
+---
+
+## Overview
+
+This guide provides step-by-step instructions for testing the multi-OIDC provider login implementation in API Explorer II.
+
+---
+
+## Prerequisites
+
+### 1. OBP API Setup
+
+Ensure your OBP API is running and configured to return well-known URIs:
+
+```bash
+# Test the endpoint
+curl http://localhost:8080/obp/v5.1.0/well-known
+
+# Expected response:
+{
+  "well_known_uris": [
+    {
+      "provider": "obp-oidc",
+      "url": "http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration"
+    },
+    {
+      "provider": "keycloak",
+      "url": "http://127.0.0.1:8180/realms/obp/.well-known/openid-configuration"
+    }
+  ]
+}
+```
+
+### 2. OIDC Providers Running
+
+Ensure at least one OIDC provider is running:
+
+**OBP-OIDC:**
+```bash
+# Check if OBP-OIDC is running
+curl http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration
+```
+
+**Keycloak (optional):**
+```bash
+# Check if Keycloak is running
+curl http://127.0.0.1:8180/realms/obp/.well-known/openid-configuration
+```
+
+### 3. Environment Configuration
+
+Set up your `.env` file with provider credentials:
+
+```bash
+# OBP API
+VITE_OBP_API_HOST=localhost:8080
+
+# OBP-OIDC Provider
+VITE_OBP_OAUTH2_CLIENT_ID=48ac28e9-9ee3-47fd-8448-69a62764b779
+VITE_OBP_OAUTH2_CLIENT_SECRET=fOTQF7jfg8C74u7ZhSjVQpoBYvD0KpWfM5UsEZBSFFM
+VITE_OBP_OAUTH2_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
+
+# Keycloak Provider (optional)
+# VITE_KEYCLOAK_CLIENT_ID=obp-api-explorer
+# VITE_KEYCLOAK_CLIENT_SECRET=your-keycloak-secret
+# VITE_KEYCLOAK_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
+
+# Session Secret
+SESSION_SECRET=your-secure-session-secret
+
+# Redis (if using)
+# VITE_OBP_REDIS_URL=redis://localhost:6379
+```

+
+## Troubleshooting
+
+### Issue: No providers available
+
+**Symptoms:**
+- Provider list is empty
+- Login button disabled or shows error
+
+**Checks:**
+1. Verify OBP API is running: `curl http://localhost:8080/obp/v5.1.0/well-known`
+2. Check backend logs for initialization errors
+3. Verify environment variables are set correctly
+4. Check OIDC providers are running and accessible
+
+**Solution:**
+```bash
+# Check OBP API
+curl http://localhost:8080/obp/v5.1.0/well-known
+
+# Check OBP-OIDC
+curl http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration
+
+# Restart backend with verbose logging
+npm run dev:backend
+```
+
+---
+
+### Issue: State mismatch error
+
+**Symptoms:**
+- Redirect to home with `?oauth2_error=invalid_state`
+- Console shows "State mismatch (CSRF protection)"
+
+**Causes:**
+- Session not persisting between requests
+- Redis not running (if using Redis sessions)
+- Multiple backend instances
+
+**Solution:**
+```bash
+# If using Redis, ensure it's running
+redis-cli ping
+
+# Check session secret is set
+echo $SESSION_SECRET
+
+# Clear browser cookies and try again
+```
+
+---
+
+### Issue: Token exchange failed
+
+**Symptoms:**
+- Error after authentication: "token_exchange_failed"
+- Backend logs show 401 or 400 errors
+
+**Causes:**
+- Wrong client ID or secret
+- OIDC provider configuration mismatch
+- Network connectivity issues
+
+**Solution:**
+```bash
+# Verify client credentials in OIDC provider
+# Check backend logs for detailed error
+# Verify redirect URI matches exactly
+```
+
+---
+
+### Issue: Provider shows as unavailable
+
+**Symptoms:**
+- Provider appears in list but marked as unavailable
+- Red status indicator
+
+**Causes:**
+- OIDC provider is down
+- Network connectivity issues
+- Health check failed
+
+**Solution:**
+```bash
+# Check provider is running
+curl http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration
+
+# Check backend logs for health check errors
+# Wait 60 seconds for next health check
+
+# Manually retry provider
+# POST /api/oauth2/providers/{name}/retry (if implemented)
+```
+
+---
+
+## Performance Testing
+
+### Load Testing Login Flow
+
+Test with multiple concurrent users:
+
+```bash
+# Install Apache Bench
+sudo apt-get install apache2-utils
+
+# Test provider list endpoint
+ab -n 100 -c 10 http://localhost:5173/api/oauth2/providers
+
+# Expected: < 100ms response time
+```
+
+### Health Check Performance
+
+Monitor health check impact:
+
+```bash
+# Watch backend logs during health checks
+tail -f backend.log | grep "health check"
+
+# Expected: Health checks complete in < 5 seconds
+```
+
+---
+
+## Security Testing
+
+### Test PKCE Implementation
+
+Verify PKCE code challenge:
+
+1. Start login flow
+2. Capture authorization URL
+3. Verify `code_challenge` and `code_challenge_method=S256` present
+
+### Test State Validation
+
+Verify CSRF protection:
+
+1. Capture callback URL with state
+2. Modify state parameter
+3. Verify callback is rejected
+
+### Test Token Security
+
+Verify tokens are not exposed:
+
+1. Check tokens are not in URL parameters
+2. Check tokens are not logged in console
+3. Check tokens are in httpOnly cookies or session only
+

+# OAuth2 Bearer Token Implementation
+## API Explorer II - Complete OAuth2/OIDC Integration Summary
+
+**Date:** December 2024  
+**Status:** ✅ Completed and Tested
+
+---
+
+## 🎯 Overview
+
+This document summarizes the complete OAuth2/OIDC integration with Bearer token authentication support for API Explorer II. The implementation allows users to authenticate via OAuth2/OIDC and make authenticated API calls to OBP-API using Bearer tokens.
+
+---
+
+## 🔧 Problem Solved
+
+### Initial Issues
+
+1. **Dependency Injection Problem**
+   - TypeDI container was not properly injecting services into controllers and middlewares
+   - `routing-controllers` was passing `ContainerInstance` instead of actual service instances
+   - Error: `isInitialized is not a function`
+
+2. **Wrong Login Endpoint**
+   - Frontend components were using `/api/connect` 
+   - Correct endpoint is `/api/oauth2/connect`
+
+3. **Client Registration Mismatch**
+   - Using client name (`obp-explorer-ii-client`) instead of client ID (UUID)
+   - OBP-OIDC requires the actual CLIENT_ID UUID for authentication
+
+4. **Missing Bearer Token Support**
+   - After OAuth2 login, API calls were failing with 401 errors
+   - `OBPClientService` only supported OAuth 1.0a
+   - No mechanism to use OAuth2 access tokens for OBP-API calls
+
+---
+
+## 🛠️ Implementation Details
+
+### 1. Fixed Dependency Injection
+
+**Problem:** Constructor parameter injection not working with TypeDI and routing-controllers
+
+**Solution:** Explicitly retrieve services from the Container in constructors
+
+**Files Modified:**
+- `server/middlewares/OAuth2AuthorizationMiddleware.ts`
+- `server/middlewares/OAuth2CallbackMiddleware.ts`
+- `server/controllers/StatusController.ts`
+- `server/controllers/RequestController.ts`
+- `server/controllers/OpeyIIController.ts`
+- `server/controllers/UserController.ts`
+
+**Pattern Used:**
+```typescript
+import { Service, Container } from 'typedi'
+
+@Service()
+export class MyController {
+  private myService: MyService
+
+  constructor() {
+    // Explicitly get service from container
+    this.myService = Container.get(MyService)
+  }
+}
+```
+
+**Why This Works:**
+- Bypasses problematic parameter injection mechanism
+- TypeDI correctly resolves services as singletons
+- Same initialized instance is used throughout the application
+
+---
+
+### 2. Updated Frontend Login Links
+
+**Files Modified:**
+- `src/components/HeaderNav.vue`
+- `src/components/ChatWidget.vue`
+- `src/components/ChatWidgetOld.vue`
+
+**Changes:**
+```vue
+<!-- Before -->
+<a href="/api/connect">Login</a>
+
+<!-- After -->
+<a href="/api/oauth2/connect">Login</a>
+```
+
+---
+
+### 3. Fixed ES Module Export
+
+**Problem:** `shared-constants.js` was compiled as CommonJS, causing Vite import errors
+
+**File Modified:** `shared-constants.js`
+
+**Before:**
+```javascript
+"use strict";
+Object.defineProperty(exports, "__esModule", { value: true });
+exports.DEFAULT_OBP_API_VERSION = 'v6.0.0';
+```
+
+**After:**
+```javascript
+// ES Module format for Vite compatibility
+export const DEFAULT_OBP_API_VERSION = 'v6.0.0'
+```
+
+---
+
+### 4. Corrected OAuth2 Configuration
+
+**File Modified:** `env_ai`
+
+**Changes:**
+```bash
+# Use actual CLIENT_ID UUID from OBP-OIDC, not the client name
+VITE_OBP_OAUTH2_CLIENT_ID=48ac28e9-9ee3-47fd-8448-69a62764b779
+
+# Use actual CLIENT_SECRET from OBP-OIDC
+VITE_OBP_OAUTH2_CLIENT_SECRET=fOTQF7jfg8C74u7ZhSjVQpoBYvD0KpWfM5UsEZBSFFM
+
+# Include /api prefix in redirect URL
+VITE_OBP_OAUTH2_REDIRECT_URL=http://localhost:5173/api/oauth2/callback
+```
+
+**OBP-OIDC Registration:**
+```
+CLIENT_NAME: obp-explorer-ii-client
+CLIENT_ID: 48ac28e9-9ee3-47fd-8448-69a62764b779
+CLIENT_SECRET: fOTQF7jfg8C74u7ZhSjVQpoBYvD0KpWfM5UsEZBSFFM
+REDIRECT_URIS: http://localhost:5173/api/oauth2/callback
+```
+
+---
+
+### 5. Implemented Bearer Token Support
+
+#### A. Updated OAuth2CallbackMiddleware
+
+**File:** `server/middlewares/OAuth2CallbackMiddleware.ts`
+
+**Added:** Creation of `clientConfig` with OAuth2 access token
+
+```typescript
+// Create clientConfig for OBP API calls with OAuth2 Bearer token
+session['clientConfig'] = {
+  baseUri: process.env.VITE_OBP_API_HOST || 'http://localhost:8080',
+  version: process.env.VITE_OBP_API_VERSION || 'v5.1.0',
+  oauth2: {
+    accessToken: tokenResponse.accessToken,
+    tokenType: tokenResponse.tokenType || 'Bearer'
+  }
+}
+```
+
+**Why This Matters:**
+- Makes OAuth2 sessions compatible with existing controller code
+- Controllers expect `session['clientConfig']` for API calls
+- Enables seamless transition from OAuth 1.0a to OAuth2
+
+#### B. Enhanced OBPClientService
+
+**File:** `server/services/OBPClientService.ts`
+
+**Added:**
+1. Extended type definition for OAuth2 support
+2. Detection logic for OAuth2 vs OAuth 1.0a
+3. Four new private methods for Bearer token authentication
+
+**Type Extension:**
+```typescript
+interface ExtendedAPIClientConfig extends APIClientConfig {
+  oauth2?: {
+    accessToken: string
+    tokenType: string
+  }
+}
+```
+
+**Detection Logic:**
+```typescript
+async get(path: string, clientConfig: any): Promise<any> {
+  const config = this.getSessionConfig(clientConfig) as ExtendedAPIClientConfig
+  
+  // Check if OAuth2 Bearer token authentication should be used
+  if (config.oauth2?.accessToken) {
+    return await this.getWithBearer(path, config.oauth2.accessToken)
+  }
+  
+  // Fall back to OAuth 1.0a
+  return await get<API.Any>(config, Any)(GetAny)(path)
+}
+```
+
+**New Bearer Token Methods:**
+- `getWithBearer()` - GET requests with Bearer token
+- `createWithBearer()` - POST requests with Bearer token
+- `updateWithBearer()` - PUT requests with Bearer token
+- `discardWithBearer()` - DELETE requests with Bearer token
+
+**Implementation Example:**
+```typescript
+private async getWithBearer(path: string, accessToken: string): Promise<any> {
+  const url = `${this.clientConfig.baseUri}${path}`
+  console.log('OBPClientService: GET request with Bearer token to:', url)
+
+  const response = await fetch(url, {
+    method: 'GET',
+    headers: {
+      Authorization: `Bearer ${accessToken}`,
+      'Content-Type': 'application/json'
+    }
+  })
+
+  if (!response.ok) {
+    const errorText = await response.text()
+    console.error('OBPClientService: GET request failed:', response.status, errorText)
+    throw new Error(`HTTP ${response.status}: ${errorText}`)
+  }
+
+  return await response.json()
+}
+```

+
+## 🔄 Authentication Flow
+
+### Complete OAuth2/OIDC Flow with Bearer Token
+
+```
+1. User clicks "Login" button
+   ↓
+2. Redirected to /api/oauth2/connect
+   ↓
+3. OAuth2AuthorizationMiddleware:
+   - Generates PKCE parameters (code_verifier, code_challenge)
+   - Generates state for CSRF protection
+   - Stores in session
+   - Redirects to OBP-OIDC authorization endpoint
+   ↓
+4. User authenticates at OBP-OIDC
+   ↓
+5. OBP-OIDC redirects back to /api/oauth2/callback?code=XXX&state=YYY
+   ↓
+6. OAuth2CallbackMiddleware:
+   - Validates state parameter
+   - Exchanges authorization code for tokens using PKCE code_verifier
+   - Retrieves user info from UserInfo endpoint
+   - Stores in session:
+     * oauth2_access_token
+     * oauth2_refresh_token
+     * oauth2_id_token
+     * oauth2_user (user info)
+     * clientConfig (with oauth2.accessToken for API calls)
+   - Redirects to original page
+   ↓
+7. User makes API call (e.g., GET /obp/v5.1.0/banks)
+   ↓
+8. Controller gets session['clientConfig']
+   ↓
+9. OBPClientService.get() called
+   ↓
+10. Service detects config.oauth2.accessToken exists
+   ↓
+11. Calls getWithBearer() with access token
+   ↓
+12. Makes HTTP request to OBP-API with:
+    Authorization: Bearer {access_token}
+   ↓
+13. OBP-API validates token and returns data
+   ↓
+14. Response returned to frontend
+```

+
+## 🧪 Testing
+
+### Manual Testing Checklist
+
+- [x] OAuth2 login flow completes successfully
+- [x] User is redirected back to original page after login
+- [x] Session persists across page refreshes
+- [x] GET /obp/v5.1.0/users/current returns authenticated user
+- [x] GET /obp/v5.1.0/banks returns bank list
+- [x] POST requests work with Bearer token
+- [x] PUT requests work with Bearer token
+- [x] DELETE requests work with Bearer token
+- [x] Logout clears all OAuth2 session data
+- [x] Token refresh works when access token expires
+
+### Test Commands
+
+```bash
+# 1. Check current user (should return user data, not 401)
+curl http://localhost:8085/api/status \
+  -H "Cookie: connect.sid=YOUR_SESSION_ID"
+
+# 2. Verify Bearer token is used in logs
+# Look for: "OBPClientService: GET request with Bearer token to:"
+
+# 3. Test API Explorer GUI
+# - Login via OAuth2
+# - Navigate to Messages or Banks tab
+# - Verify data loads without 401 errors
+```
+

+
+## 🎓 Key Learnings
+
+### 1. TypeDI and routing-controllers Integration
+
+**Issue:** Constructor parameter injection doesn't work reliably with routing-controllers
+
+**Solution:** Use explicit `Container.get()` in constructors
+
+**Lesson:** When integrating multiple frameworks, always verify DI behavior
+
+### 2. Client ID vs Client Name
+
+**Issue:** OAuth2 providers use UUIDs as client IDs, not friendly names
+
+**Solution:** Always use the UUID from provider, store name for documentation
+
+**Lesson:** Check provider logs to confirm exact client registration format
+
+### 3. Session Compatibility
+
+**Issue:** Different auth methods need different session structures
+
+**Solution:** Create compatible session structure that works for both patterns
+
+**Lesson:** When migrating auth systems, maintain backward compatibility in session data
+
+### 4. Bearer Token Authentication
+
+**Issue:** OBP API supports both OAuth 1.0a and OAuth2 Bearer tokens
+
+**Solution:** Detect auth type and route to appropriate implementation
+
+**Lesson:** Support multiple auth methods during transition period

+
+## 🚀 Production Considerations
+
+### Security
+
+1. **Token Storage**
+   - Access tokens stored in Redis-backed sessions
+   - HttpOnly cookies prevent XSS attacks
+   - Secure flag should be enabled in production
+
+2. **Token Refresh**
+   - Refresh tokens are stored and can be used
+   - `UserController.current()` checks token expiry
+   - Automatic refresh implemented for expired tokens
+
+3. **HTTPS Required**
+   - All OAuth2 flows should use HTTPS in production
+   - Update `VITE_OBP_OAUTH2_REDIRECT_URL` to https://
+   - Configure nginx/reverse proxy for SSL termination
+
+### Configuration
+
+**Production Environment Variables:**
+```bash
+# Use production OIDC provider
+VITE_OBP_OAUTH2_WELL_KNOWN_URL=https://auth.yourdomain.com/.well-known/openid-configuration
+
+# Use production client credentials
+VITE_OBP_OAUTH2_CLIENT_ID=<production-client-uuid>
+VITE_OBP_OAUTH2_CLIENT_SECRET=<production-secret>
+
+# Use HTTPS redirect URL
+VITE_OBP_OAUTH2_REDIRECT_URL=https://explorer.yourdomain.com/api/oauth2/callback
+
+# Enable secure cookies
+NODE_ENV=production
+
+# Use secure Redis connection
+VITE_OBP_REDIS_URL=rediss://production-redis:6379
+```
+
+### Monitoring
+
+**Log Messages to Monitor:**
+- `OAuth2Service: Initialization successful` - Startup check
+- `OAuth2CallbackMiddleware: Authentication flow complete` - Successful logins
+- `OBPClientService: GET request with Bearer token to:` - API calls using OAuth2
+- `UserController: Token refresh successful` - Automatic token refresh
+- Token exchange failures (indicate provider issues)
+- Bearer token authentication failures (indicate token issues)
+
+### Performance
+
+- Redis session store provides fast session lookup
+- Bearer token requests are stateless at OBP-API level
+- Consider implementing token caching if needed
+- Monitor OBP-API response times with Bearer tokens
+
+---
+
+## 🔍 Debugging Tips
+
+### Check Session Data
+```javascript
+// In browser console
+document.cookie
+
+// In Redis CLI
+redis-cli
+> KEYS sess:*
+> GET sess:YOUR_SESSION_ID
+```
+
+### Enable Debug Logging
+```bash
+# Server logs
+DEBUG=express-session npm run dev
+
+# Check OAuth2 flow
+# Look for logs prefixed with "OAuth2"
+```
+
+### Common Issues
+
+**Issue: 401 errors after login**
+- Check: `session['clientConfig']` exists
+- Check: `clientConfig.oauth2.accessToken` is set
+- Check: Token not expired
+- Solution: Verify OAuth2CallbackMiddleware creates clientConfig
+
+**Issue: "Client validation failed"**
+- Check: Using CLIENT_ID UUID, not client name
+- Check: CLIENT_SECRET matches OBP-OIDC
+- Check: REDIRECT_URI matches OBP-OIDC registration
+- Solution: Update env_ai with correct values
+
+**Issue: PKCE validation failed**
+- Check: Redis is running (session persistence)
+- Check: Session cookie is being set
+- Check: code_verifier stored in session
+- Solution: Verify Redis connection and session config
+

+# OAuth2 Dependency Injection Fix
+
+## Problem
+
+When the OAuth2 authorization flow was initiated, the `OAuth2AuthorizationMiddleware` was receiving a `ContainerInstance` object instead of the actual `OAuth2Service` instance. This caused the following error:
+
+```
+OAuth2AuthorizationMiddleware: oauth2Service is: ContainerInstance {
+  services: [...],
+  id: 'default'
+}
+OAuth2AuthorizationMiddleware: oauth2Service type: object
+OAuth2AuthorizationMiddleware: isInitialized is not a function
+OAuth2AuthorizationMiddleware: Available methods: [ 'services', 'id' ]
+```
+
+## Root Cause
+
+The issue was caused by how `routing-controllers` handles dependency injection when using the `@UseBefore()` decorator with middleware classes.
+
+When you use `@UseBefore(OAuth2AuthorizationMiddleware)` on a controller, `routing-controllers` attempts to instantiate the middleware, but the constructor parameter injection wasn't working correctly with TypeDI despite calling `useContainer(Container)`.
+
+### Original Code (Broken)
+
+```typescript
+@Service()
+export default class OAuth2AuthorizationMiddleware implements ExpressMiddlewareInterface {
+  constructor(private oauth2Service: OAuth2Service) {}
+  
+  async use(request: Request, response: Response): Promise<void> {
+    // oauth2Service was receiving ContainerInstance instead of OAuth2Service
+    if (!this.oauth2Service.isInitialized()) { // Error: isInitialized is not a function
+      // ...
+    }
+  }
+}
+```
+
+## Solution
+
+Instead of relying on constructor parameter injection, we explicitly retrieve the `OAuth2Service` from the TypeDI container inside the constructor:
+
+### Fixed Code
+
+```typescript
+import { Service, Container } from 'typedi'
+import { OAuth2Service } from '../services/OAuth2Service'
+
+@Service()
+export default class OAuth2AuthorizationMiddleware implements ExpressMiddlewareInterface {
+  private oauth2Service: OAuth2Service
+
+  constructor() {
+    // Explicitly get OAuth2Service from the container to avoid injection issues
+    this.oauth2Service = Container.get(OAuth2Service)
+  }
+
+  async use(request: Request, response: Response): Promise<void> {
+    // Now oauth2Service is correctly the OAuth2Service instance
+    if (!this.oauth2Service.isInitialized()) {
+      // Works correctly
+    }
+  }
+}
+```
+
+## Files Modified
+
+1. **`server/middlewares/OAuth2AuthorizationMiddleware.ts`**
+   - Changed from constructor parameter injection to explicit container retrieval
+   - Removed debugging console.log statements
+
+2. **`server/middlewares/OAuth2CallbackMiddleware.ts`**
+   - Applied the same fix for consistency
+   - Changed from constructor parameter injection to explicit container retrieval
+
+## Why This Works
+
+By using `Container.get(OAuth2Service)` explicitly:
+
+1. We bypass the problematic parameter injection mechanism
+2. TypeDI correctly resolves the service as a singleton
+3. The same instance that was initialized in `app.ts` is retrieved
+4. All methods (`isInitialized()`, `createAuthorizationURL()`, etc.) are available
+
+## Testing
+
+After this fix, the OAuth2 flow should work correctly:
+
+1. User navigates to `/api/oauth2/connect`
+2. `OAuth2AuthorizationMiddleware` successfully retrieves `OAuth2Service`
+3. PKCE parameters are generated
+4. User is redirected to the OIDC provider
+5. After authentication, callback to `/api/oauth2/callback` works
+6. `OAuth2CallbackMiddleware` exchanges the code for tokens
+7. User information is retrieved and stored in session
+8. User is redirected back to the original page

+
+## Technical Notes
+
+### Why Not Global Middleware Registration?
+
+We could have registered the middleware globally in `useExpressServer()` configuration, but using `@UseBefore()` provides:
+- Better route-specific control
+- Clearer code organization
+- Explicit middleware ordering per endpoint
+
+### TypeDI Singleton Behavior
+
+The `@Service()` decorator on `OAuth2Service` makes it a singleton by default, so:
+- `Container.get(OAuth2Service)` always returns the same instance
+- The instance initialized in `app.ts` with `initializeFromWellKnown()` is the same one used in middleware
+- No duplicate initialization occurs

+# OAuth2/OIDC Quick Start Guide
+## API Explorer II Integration with OBP-OIDC
+
+**Quick reference for developers getting started with OAuth2/OIDC integration**
+
+---
+
+## 🚀 Quick Setup (15 minutes)
+
+### Step 1: Set Up OBP-OIDC (5 minutes)
+
+```bash
+# Navigate to OBP-OIDC directory
+cd ~/Documents/workspace_2024/OBP-OIDC
+
+# Copy example configuration
+cp run-server.example.sh run-server.sh
+
+# Edit database credentials (IMPORTANT!)
+vim run-server.sh
+# Update: DB_HOST, DB_PORT, DB_NAME, OIDC_USER_PASSWORD, OIDC_ADMIN_PASSWORD
+
+# Start the OIDC server
+./run-server.sh
+```
+
+**Verify it's running:**
+```bash
+curl http://localhost:9000/obp-oidc/.well-known/openid-configuration
+```
+
+### Step 2: Configure API Explorer II (5 minutes)
+
+```bash
+# Navigate to API Explorer II
+cd ~/Documents/workspace_2024/API-Explorer-II
+
+# Install new dependencies
+npm install arctic jsonwebtoken @types/jsonwebtoken
+
+# Update .env file
+cat >> .env << EOF
+
+# OAuth2/OIDC Configuration
+VITE_USE_OAUTH2=true
+VITE_OBP_OAUTH2_CLIENT_ID=obp-explorer-ii-client
+VITE_OBP_OAUTH2_CLIENT_SECRET=CHANGE_THIS_TO_EXPLORER_SECRET_2024
+VITE_OBP_OAUTH2_REDIRECT_URL=http://localhost:5173/oauth2/callback
+VITE_OBP_OAUTH2_WELL_KNOWN_URL=http://127.0.0.1:9000/obp-oidc/.well-known/openid-configuration
+EOF
+```
+
+**Note:** The client secret above matches the default in OBP-OIDC's `run-server.sh`. Change it to your actual secret.
+
+### Step 3: Verify Prerequisites (2 minutes)
+
+```bash
+# Check Redis is running
+redis-cli ping
+# Expected output: PONG
+
+# Check OBP-API is running
+curl http://localhost:8080/obp/v5.1.0/root
+# Expected: JSON response
+
+# Check Node version
+node --version
+# Expected: v16.14.0 or higher
+```
+
+### Step 4: Test the Setup (3 minutes)
+
+```bash
+# Start API Explorer II
+npm run dev
+
+# Open browser to http://localhost:5173
+# Click "Login" button
+# Should redirect to OBP-OIDC login page
+```
+
+**Test credentials** (default OBP-OIDC users):
+- Username: `user@example.com`
+- Password: (check your OBP database)
+

+    }
+  }
+}
+```
+

+
+## 🧪 Testing Your Implementation
+
+### Manual Testing Flow
+
+1. **Start all services:**
+   ```bash
+   # Terminal 1: OBP-OIDC
+   cd ~/Documents/workspace_2024/OBP-OIDC
+   ./run-server.sh
+
+   # Terminal 2: Redis
+   redis-server
+
+   # Terminal 3: API Explorer II
+   cd ~/Documents/workspace_2024/API-Explorer-II
+   npm run dev
+   ```
+
+2. **Test login flow:**
+   - Open http://localhost:5173
+   - Click "Login" button
+   - Should redirect to http://localhost:9000/obp-oidc/auth
+   - Enter credentials
+   - Should redirect back to http://localhost:5173
+   - Username should appear in header
+
+3. **Test session persistence:**
+   - Refresh the page
+   - Should remain logged in
+   - Username still visible
+
+4. **Test logout:**
+   - Click "Logout" button
+   - Should redirect to home
+   - No longer authenticated
+
+### Debugging Tips
+
+**Enable debug logging:**
+```bash
+DEBUG=express-session npm run dev
+```
+
+**Check session in Redis:**
+```bash
+redis-cli
+> KEYS sess:*
+> GET sess:<your_session_id>
+```
+
+**Check OIDC configuration:**
+```bash
+curl http://localhost:9000/obp-oidc/.well-known/openid-configuration | jq
+```
+
+**Monitor logs:**
+- Watch server console for "OAuth2:" prefixed messages
+- Watch browser console for errors
+- Check OBP-OIDC terminal for authentication attempts
+
+---
+
+## 🐛 Common Issues & Solutions
+
+### Issue: "OIDC configuration not initialized"
+**Cause:** Well-known URL not reachable or OAuth2Service not initialized
+
+**Solution:**
+```bash
+# Check OBP-OIDC is running
+curl http://localhost:9000/obp-oidc/.well-known/openid-configuration
+
+# Verify environment variable
+echo $VITE_OBP_OAUTH2_WELL_KNOWN_URL
+
+# Check server logs for initialization error
+```
+
+### Issue: "State validation failed"
+**Cause:** Session not persisting between requests
+
+**Solution:**
+```bash
+# Check Redis is running
+redis-cli ping
+
+# Verify Redis connection in server logs
+# Should see: "Connected to Redis instance: ..."
+
+# Check session cookie in browser DevTools (Application > Cookies)
+```
+
+### Issue: "Code verifier not found in session"
+**Cause:** Session expired or cookie not set
+
+**Solution:**
+- Clear browser cookies
+- Check session timeout settings in `server/app.ts`
+- Verify `VITE_OPB_SERVER_SESSION_PASSWORD` is set
+
+### Issue: "Token request failed: 401"
+**Cause:** Invalid client credentials
+
+**Solution:**
+```bash
+# Verify client credentials match OBP-OIDC configuration
+grep OIDC_CLIENT_EXPLORER ~/Documents/workspace_2024/OBP-OIDC/run-server.sh
+
+# Check credentials in .env
+grep VITE_OBP_OAUTH2 .env
+```
+
+### Issue: Redirect loop
+**Cause:** Cookies not being set properly
+
+**Solution:**
+- Check cookie settings in `server/app.ts`
+- If using nginx, verify `X-Forwarded-Proto` header
+- Set `app.set('trust proxy', 1)` if behind reverse proxy
+

+## 🎯 Next Steps
+
+After completing the quick start:
+
+1. **Read the full preparation document** (`OAUTH2-OIDC-INTEGRATION-PREP.md`)
+2. **Implement remaining phases** (see Phase 2-6 in main document)
+3. **Write comprehensive tests** (unit, integration, E2E)
+4. **Update documentation** (README, migration guide)
+5. **Plan production deployment** (see deployment section in main doc)
+
+---
+
+## 💡 Tips for Success
+
+1. **Keep OAuth 1.0a working** - Don't remove old code until OAuth2 is stable
+2. **Use feature flags** - `VITE_USE_OAUTH2` allows easy rollback
+3. **Test thoroughly** - OAuth2 flows have many edge cases
+4. **Monitor closely** - Watch logs and metrics during rollout
+5. **Document everything** - Future you will thank present you

+## 🎨 Architecture Overview
+
+### Current State (OAuth 1.0a)
+```
+User → Login → OAuth 1.0a Flow → OBP-API → Callback → Session
+```
+
+### Target State (OAuth2/OIDC)
+```
+User → Login → OAuth2 Flow → OBP-OIDC → Token Exchange → Session
+                                ↓
+                            JWT Tokens (Access + Refresh + ID)
+```
+
+### Key Changes
+
+| Aspect | Before (OAuth 1.0a) | After (OAuth2/OIDC) |
+|--------|---------------------|---------------------|
+| **Auth Method** | HMAC-SHA1 signatures | Bearer tokens (JWT) |
+| **Tokens** | Access token + secret | Access + Refresh + ID tokens |
+| **User Info** | API calls | ID token claims |
+| **Refresh** | Not supported | Automatic refresh |
+| **Providers** | Single (OBP-API) | Multiple (OBP-OIDC, Keycloak, etc.) |

+✅ **Modern Standard** - Industry-standard authentication
+✅ **Better Security** - JWT tokens, PKCE flow, short-lived tokens
+✅ **Auto Refresh** - Seamless token renewal
+✅ **Multi-Provider** - Support for multiple identity providers
+✅ **Better UX** - SSO capabilities, cleaner flow
+✅ **Mobile Ready** - Native OAuth2 support in mobile apps
+
+### Backward Compatibility
+
+✅ **Feature Flag** - Switch between OAuth 1.0a and OAuth2
+✅ **Gradual Migration** - Both methods work simultaneously
+✅ **Easy Rollback** - Revert with a single environment variable
+✅ **No Breaking Changes** - Existing OAuth 1.0a code untouched
+
