**Description**  
Error 400 Bad Request when requesting access token refresh

**Error?**  
I get an error trying to refresh token right away after adding a Zoom app.  
There is a ton of similar articles on the forum but I have not found any solutions I could apply.

**How To Reproduce**  
_Steps to reproduce the behavior:_

1. Redirect user to Zoom App install link: [Sign In - Zoom](https://zoom.us/oauth/authorize?redirect_uri=https%3A%2F%2Fover-quota-dev.ngrok.io%2Fzoom-auth&response_type=code&client_id=BzenFJSwOdkXXvmxFLEg)
2. Accept the integration request
3. Zoom redirects user to an app backend callback with a code.
4. Backend requests auth&refresh tokens using a code.
5. Backend stores auth and refresh tokens in the database.
6. Manually I post a request in PostMan (see a screenshot above) using basic Auth (username BzenFJSwOdkXXvmxFLEg and password), body is x-www-form-urlencoded with the next params: grant\_type=refresh\_token and refresh\_token equal the one I got on step 5.
7. Zoom responds with status 400 and body {“reason”: “Invalid Token!”, “error”: “invalid\_grant”}
