   .../obp/v1.4.0/ 404 Not Found
2. Double check parameters are spelt correctly (including http vs https etc.)
3. Check your encoding (use UTF8)

There are two ways to authenticate a user: OAuth and Direct Login. If you are using this sandbox for a hackathon, we recommend you use Direct Login to authenticate as it is easier than the OAuth workflow.

###

If you want to use OBP with OAuth, we recommend you use (and fork) one of our OAuth Starter SDKs. If you are using this sandbox for a hackathon, we recommend you use Direct Login. For an OAuth walkthrough example with sample code, please see here. We use OAuth 1.0a. For deepish technical details of the flow see here.
We also support OAuth 2.0. For the technical details of using OBP API with OAuth 2.0, please see here.
