Sure! @tabryant Here is the link to our Docs on Acces token generation: > **[Server-to-Server OAuth](https://developers.zoom.us/docs/internal-apps/s2s-oauth/#use-account-credentials-to-get-an-access-token)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. ---

Perfect, thank you. We have found the issue to be the way the the API was set up to authenticate using client vs. account. Using account\_credentials resolved it. Thanks again for your help! ---
