As that JWT is going to be deprecated, we were shifting from JWT to S2S.

Unfortunately, I can not access the Zoom Master API endpoints using the access token generated from S2S app. Rest of the endpoints work, but whenever I try to list webinars of subaccount. It gives me invalid access token error.

Can you please assist? We want to proceed with S2S. ( server 2 server oauth ).

@zoom73 ,

Is your server to server oauth app created under the master account?

@zoom73 ,

does the s2s app type have all the necessary scope to list all webinars?
