**Description**  
We have an app that is published on the marketplace for around a year now. Things have been working as usual until now, but recently we noticed that when we refresh an user’s access token we get an invalid\_client error. We have not changed our client\_id and client\_secret since release.

This error happens sporadically and we can’t identify any pattern for why it occurs. It would be great if someone can explain why we receive this error.

**Error**

{  
“reason”: “Invalid client\_id or client\_secret”,  
“error”: “invalid\_client”  
}

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
OAuth

**Which Endpoint/s?**  
[https://zoom.us/oauth/token?grant\_type=refresh\_token&refresh\_token=](https://zoom.us/oauth/token?grant_type=refresh_token&refresh_token=)\<refresh\_token\>

Hi @user.mix @scottjg,

When you run into this issue, can you share an example token that threw the error with us at [developersupport@zoom.us](mailto:developersupport@zoom.us)? Someone from our team will be happy to further investigate.
