Pega REST Integration with Service via API gateway using JWT authentication

We have created the REST-Connect and configured the authorisation profile, and JWT Token profile. Also uploaded the JKS file, and provided the Keystore and alias name and password. Now we are trying to connect from Pega to the API gateway, where we have already created a client for Pega with the required information. We are facing issues and getting an 403 Forbidden error while trying to retrieve the access token back from the server. If you have worked on a similar use case, can you please guide what needs to be done to configure authentication using JWT bearer token.

Do we need to call the pxgenerateJWT activity to pass on the JWT token?

@ARUPM377 Based on a similar use case here are some steps you can follow to troubleshoot and resolve the issue: 1. Ensure Correct Scope/Permissions: Verify that the JWT token has the correct scope and permissions required by the API gateway. This was a common issue in a similar scenario where the problem was with the scope/permissions of the JWT Bearer token. 2. Generate JWT Token: Yes you need to call the pxGenerateJWT activity to generate the JWT token. Ensure that the JWT token is correctly generated and includes all necessary claims. 3. Check Keystore Configuration: Make sure that the JKS file keystore alias name and password are correctly configured and accessible by Pega. 4. Validate JWT Token: Validate the generated JWT token to ensure it is correctly formatted and signed. You can use online JWT validators for this purpose. 5. API Gateway Configuration: Double check the client configuration on the API gateway to ensure it matches the information provided by Pega. 6. Debug Logs: Enable debug logs in Pega to get more detailed information about the error. This can help identify if there are any issues with the token generation or the API call. If you follow these steps and still face issues it might be helpful to review the specific error message returned by the API gateway for more clues.
