I downloaded the archive zoom-c-sharp-wrapper-5.2.42037.1112. I registered on the site, received a token and decided to test the work of the provided example Zoom\_sdk\_demo. The app doesn’t work. In debug mode, got the error SDKERR\_UNINITIALIZE

**Which version?**  
SDK v5.2.42037.1112  
OS Windows 10 Pro

Hey @SmartSoftware,

Thanks for using the dev forum!

Currently the Zoom Marketplace does not provide a token for initializing the SDK automatically. The JWT token that is expected by the SDK must created using your SDK Key and SDK Secret. Did you by chance use the JWT provided in the JWT section of Zoom Marketplace? If so, that JWT is for the Zoom API and not the SDK.

Thanks!  
Michael

Hello. Thanks for the help. Yes, I misunderstood and used the JWT provided in the JWT section of the Zoom Marketplace.
