Token Validation Challenges Between Auth0 and SAP BRIM APIs

I’ve been working on integrating Auth0 authentication with SAP Billing and Revenue Innovation Management (BRIM), specifically around the BRSOM component. The setup involves exposing SAP endpoints through a middleware layer to manage authentication and authorization flows using Auth0-issued tokens.

The connection itself works, but I’m running into token validation issues, SAP occasionally rejects valid tokens midway through their lifespan. It doesn’t appear to be an expiry issue; it feels more like an audience or clock synchronization mismatch between Auth0, the API gateway, and SAP.

Since I’ve been exploring this scenario while studying for the C_BRSOM_2020 certification exam, I’ve been using Pass4Future hands-on resources to simulate integration patterns and test authentication flows. It’s been helpfu

l for understanding the structure, but this particular validation inconsistency remains unresolved.

Has anyone here dealt with similar token validation timing issues in enterprise-level SAP integrations? I’d appreciate insights into how you stabilized the authentication cycle or configured token audience claims more effectively.

Thanks in advance
