Need to Restrict Fusion API Access for External System

Hi,

We're trying to give an external system access to a single Fusion application API. We've set up a confidential application with OAuth Authorization Code, but the current scope is too broad, granting access to all APIs instead of the intended one. The external system must be restricted to calling only this specific API.

The current scope of the confidential application is shown in the below screenshot.

Please suggest.

Regards,

Zubair
