SAP BTP integration suite giving 403 error while triggers data from SAP

[S0025445531]

While doing integration from Happay to SAP ERP through Happay application. We are integrating using Rest API using HTTPS protocol.While triggering data from Postman we can able to get data into CPI and the same data successfully posted to the ERP system and getting the response back from ERP to postman. Please find the below screenshot:

But once we are trigger the data from the Happay application the data is not coming to CPI and those Happay team getting the 403 forbidden error.

We are doing this integration using oauth 2.0 token based.

The below step(in the above mentioned blog) is missing which was the root cause.

Go to Security > Authorizations and assign the user with name oauth_client_<client ID> to the role ESBMessaging.send. Alternatively, you can assign a custom role to this user in case you like to make sure that permissions to process messages on the runtime node should be defined per integration flow endpoint.

Hi ajay.rimkar,

This could be related to role assignment in case you are getting a 403 Forbidden error.

If that is the case, then for client credentials authorization in the Neo environment, you need to assign the role to oauth_client_<clientID> in SAP BTP Cockpit as explained here.
