Description We have implemented oauth flow with zoom ( https://marketplace.zoom.us/docs/guides/auth/oauth ) and in general it works great. However, we are seeing that after a few days, the calls to refresh the oauth token start to fail and token can never be refreshed. Users are forced to re-authenti…

Hey @pablo.fredes , Please try the OAuth and refresh flow in Postman and see if it works. It could very well be a misconfiguration in your code. Thanks, Tommy

Yes @tommy still getting a error: Client error: POST https://zoom.us/oauth/token resulted in a 401 Unauthorized response: {“reason”:“Invalid Token!”,“error”:“invalid_request”} Im using this app in my local machine and not using different devices…

@tommy I can register with the first auth token but the refresh token is always invalid. The webinar ID is 91308815810. Is it some configuration error on the Oauth app?

Hey @pablo.fredes , Happy to hear you figured out the issue! Let me know if you need anything else! :slight_smile: Thanks, Tommy

Hey @greminders , Thanks so much for jumping in and helping out—great context for our developers! Best, Will

Hope this helps others: different environments will invalidate the others’ refresh tokens. For example, user on dev server does oAuth workflow. user on staging server does oAuth with same account dev server user tries to use access token. it fails, so it tries refresh. Invalid token error. dev ser…

Thanks for sharing your experience with our community @viddd :slight_smile:
