IDCS: 400 Bad Request using Oauth with Fusion and OIC (Doc ID 2869126.1)

Last updated on MAY 20, 2022

Applies to:

Identity Cloud Service (IDCS) - Version N/A to N/A
Information in this document applies to any platform.

Symptoms

 One of our entity configured the OAuth to access our fusion application webservices from their OIC (Oracle Integration). So for this, they created custom client and server application in Oracle OIC IDCS and configured everything in OIC but they are getting the authentication issue when they try to login via OAuth.

OAuth configuration with Fusion and OIC: https://www.youtube.com/watch?v=HY1rVixlcPo 

OIC Consent page does not show up and shows 400 Bad Request.

 

Changes

Imported CA certificate to Fusion POD: https://docs.oracle.com/en/cloud/paas/identity-cloud/uaids/obtain-root-ca-certificate-oracle-identity-cloud-service.html


Checked the configuration of both applications to be matching the one in the video and upon re-testing it still errors out with 400 Bad Request on OIC /callback URL; 

Given that the scope is defined correctly and the /callback complains about the Scope, it means that the listed Fusion scope is unreachable;
