We offers cloud service for sales department and user can use zoom app by oauth integration .
Today (January 23, 2023 at approximately 1:30 p.m. Japan time.), Suddenly, all customer’s access token updates are failing with 400 Error.
We have confirmed that the fisrt authorization of our oauth app is successful and that an access token and a refresh token are generated. However, updating the access token with the refresh token issued at that time always fails.
We also made sure that the execution environment, including code and environment variables, had not changed at that time.
Because token updates fail, we are unable to guide customers to re-authorize the application, which has a significant business impact.
How To Reproduce Steps to reproduce the behavior: 1. User does Oauth linkage and get access token and refresh token 2. Send a request for a new access token to https://zoom.us/oauth/token using the issued refresh token 3. 400 Error happens
Hi @jigenji, @daiki.murakami@freelancer.nak, @Maxime622, this issue should now be resolved. Can you confirm you’re now able to successfully refresh access tokens to apps previously returning errors? You should not need to reauthenticate, existing refresh tokens will now work.
Our apologies for the disruption and thank you for reporting here.
