Hey @ross,

Thank you for reaching out to the Zoom Developer Forum. When you request a new access_token, the previous refresh_token becomes invalidated. It sounds like a new access_token was requested - maybe as part of testing - and this caused the refresh_token that was held to be invalid.

Let me know if that helps.

Thanks,
Max
