**Description**  
I’m trying to refresh the access\_token by using the refresh\_token but ended up getting an error

**Error**

> “reason”: “Invalid Token!”, “error”: “invalid\_request”

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

> OAuth

**Which Endpoint/s?**

> [https://zoom.us/oauth/token](https://zoom.us/oauth/token)

**How To Reproduce (If applicable)**  
Steps to reproduce the behavior:

> CLIENT\_ID = \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*;  
> CLIENT\_SECRET = \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*;  
> $refreshToken = \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*;
> 
> $url = “[https://zoom.us/oauth/token?grant\_type=refresh\_token&refresh\_token=](https://zoom.us/oauth/token?grant_type=refresh_token&refresh_token=)”.$refreshToken;  
> $header = array(  
> ‘Content-Type: application/json’,  
> 'Authorization: Basic '. base64\_encode(CLIENT\_ID.“:”.CLIENT\_SECRET)  
> );  
> $ch = curl\_init();  
> curl\_setopt($ch, CURLOPT\_URL, $url);  
> curl\_setopt($ch, CURLOPT\_HTTPHEADER, $header);  
> curl\_setopt($ch,CURLOPT\_POST, 1);  
> curl\_setopt($ch,CURLOPT\_RETURNTRANSFER, true);  
> $response = curl\_exec($ch);  
> curl\_close ($ch);  
> $result = json\_decode($response, true);

Can someone tell me why this is happening?

Thanks

Hey @hashwide,

Can you ensure that you’re using the latest refresh\_token value? Note that the refresh\_token is updated each time a new access\_token is fetched—you will need to update this token each time.

Thanks,  
Will
