Hi @tommy,

I am getting 401 as invalid token when i am trying to get refresh token, by using  
url, [https://zoom.us/oauth/token?grant\_type=refresh\_token&refresh\_token=](https://zoom.us/oauth/token?grant_type=refresh_token&refresh_token=){refresh token}.  
Or, Is there any time limit for refresh token.  
header value is, Authorization:Basic Base64 Encoding(client Id:client secret).

Thanks,  
Prem

Hi @prem.srivastava,

There is no time limit for a refresh token. Is this the latest refresh token that was generated with last access token that you’ve used?

Normally when you get this error, there has been newer refresh token that has been recently generated.

Thanks

Hi @prem.srivastava,

Can you send us your access token and refresh token to [developersupport@zoom.us](mailto:developersupport@zoom.us) so that we can take a closer look?

Thanks
