Zoom Meeting SDK (Windows C# wrapper) — Authentication Error with SDKAuth

Meeting SDK Windows
1

Hi,

I’m working with the Zoom Meeting SDK (Windows C# wrapper) in my WPF/.NET project.
The SDK initializes successfully, but when I try to call SDKAuth() with my JWT token, I get the following error:

Error: (ZOOM_SDK_DOTNET_WRAP.CZoomSDKeDotNetWrap.Instance
       .GetAuthServiceWrap().SDKAuth(param)) SDK internal error

Sometimes I also see:

Error: Unauthentication (when calling MeetingService.Join)

I generated a JWT using my app credentials (Client ID & Secret) but the SDK does not seem to accept it.

Has anyone faced this issue before?

  • Am I missing a specific setting in the Zoom Marketplace App setup?

  • Or do I need to use a different set of credentials (SDK Key/Secret vs Client ID/Secret)?

Any guidance would be greatly appreciated.
