Where to enter redirect URL / whitelist URL for Server-to-Server OAuth app?

Hello,
I am creating a Server-to-Server OAuth APP and would like to know how to configure the Redirect URL or Whitelist URL for this app type.

I am unable to find these options in the app settings. Could you please guide me on where and how the whitelist URLs can be configured?

Hello Ankita!

Server to server Oauth apps don’t have redirect or whitelist url fields cuz they are machine to machine intergrations.

Thanks for your reply,
I have been integrating Zoom with my Salesforce org using Named Credentials and External Credentials. However, while calling any Zoom API, I am getting an “Invalid access token” error.
How do we solve this error.

Maybe the token has expired or it was fetched without right parameters in salesforce make sure your ext credential configuration is passing the grant_type=account_credentials parameter along with your zoom account ID to the token endpoint also check if your app is actually activated if it’s in a draft state zoom API will reject tokens or label them as invalid.

@James3265166 The Named credentials and the external credentials seems fine to me. And the app is activated in the zoom marketplace.
External Credentials -

Named Credentials -

External Auth Identity Providers -

Can you please look into the named credentials/external credentials.

Oauth 2.0 and zooms S2S token endpoints payload parameters like grant type and account ID must be sent as URL encoded body data go-to the body tab of your req change the radio button from data to x-www-form-urlencoded and move your key value pairs there this should do the trick.
