Previous access token / refresh token stops working after requesting a new access token

Using a general app we can get a valid access token through postman with authorization code. However, if we use the same application to get a new access token, the first access token stops working, even though the expiration time has not passed. The same goes to the refresh token. The refresh token from a previous call won’t work, if we get a new access token.

If we try to use the access token, after a new one for the same application was created we get this error:  
{  
“code”: 124,  
“message”: “Invalid access token.”  
}

If we try to use the refresh token, after a new access token was created we get this error:  
{  
“reason”: “Invalid Token!”,  
“error”: “invalid\_grant”  
}

**How To Reproduce**  
1- Get an access token with authorization code and access Get [https://api.zoom.us/v2/report/activities](https://api.zoom.us/v2/report/activities) (for example).  
2- Get a new access token and access another API (for example).  
3- Try accessing the same API in step 1 with the same access token you used in step 1.

\_\_\_\_\_\_\_\_\_\_\_\_\_ same with refresh token\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_  
1- Get access token, use refresh token to get a new access token.  
2- Get a new access token  
3- Try to use the refresh token you generated in 1. It won’t work.

The behavior you’re observing is expected. Generating a new token invalidates the previous one, even if it is before the token expiry time.
