Reusing Salesforce App (V1)’s OAuth Authorization for manual API calls

Hi all,

We have just upgraded our Salesforce Zoom app/package (V1) after JWT authentication getting deprecated.

Apart from the “standard” functionality of the app/package, we also have a few “manual” API calls in our Apex code (e.g. fetching registrants for a meeting via `/meetings/[meeting_id]/registrants` etc.).

For these API calls we used to authenticate by generating the JWT token from the fields zoom_app__Zoom_API_Secret__c and zoom_app__Zoom_API_Key__c which are stored in the Salesforce org as part of the app/package config.

Now that the app/package is authorized via OAuth, is there a way to use that existing authorization in the “manual” API calls made from Apex?

If not, what is the recommended way to authorize these manual API calls?

Many thanks!
