Hi @paul.deehan ,

Which specific SDK and version are you using? Additionally, can you please clarify what SDK credentials you’re using exactly? There’s a few threads on this, and I encourage you to check out some of them, like this one:

> Hey @russliu, Thank you for reaching out to the Zoom Developer Forum. It looks like you’re using an SDK key and secret. When it comes to the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk), make sure that you are using a [JWT App](https://marketplace.zoom.us/docs/guides/auth/jwt)’s API Key and Secret. Let me know if that helps. Thanks, Max

Thank you!
