Error with getting token when executing API call

arthurperry3 — Mon, 19 Jun 2023 22:34:35 GMT

Tutorials: https://developers.sap.com/tutorials/cp-starter-isuite-api-management.html
--------------------------

When following this tutorial, there is a 500 error when getting the auth token via the OAuth access policy. Testing the token endpoint with Postman, I receive

{ "error": "invalid_request", "error_description": "Missing grant type"

}

It is missing the grant_type=client_credentials payload in thegetoauthtoken step. I added the following to the <ServiceCallout>:

<Payload contentType="application/x-www-form-urlencoded">grant_type=client_credentials</Payload>

This eliminates the above error, but I still get a 500 error : An internal server error occured: The MPL ID for the failed message is : AGSQ1x3o51owaNCdcApVRyFI0reA

Any ideas?

Hello Arthur,

Can you goto cloud integration monitoring and see what error you are getting?

The MPL id mentioned in APIM response is from Cloud integration.

Regards,

Sri
