**Description**  
I want to refresh the access\_token by using the refresh\_token but I only ended up getting this error ` "reason": "Invalid Token!", "error": "invalid_request"`

I am using the exact refresh\_token I got by the time I get the access token given by my redirect zoom redirect URI.

**Error**  
` "reason": "Invalid Token!", "error": "invalid_request"`

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

**Which Endpoint/s?**  
` https://zoom.us/oauth/token`

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

request URL = [https://zoom.us/oauth/token](https://zoom.us/oauth/token)?

Exact code using PHP / Laravel Framework

```
$url = 'https://zoom.us/oauth/token?';
$client_id = ' ********************************';
$client_secret = ' *****************************';

$param = array(
    'grant_type' => 'refresh_token',
     //refresh_token is coming from the request
    'refresh_token' => $request->refresh_token,
);

$headers = array(
    "Authorization: Basic ". base64_encode($client_id.":".$client_secret),
    "content-type: application/json"
);

$params = http_build_query($param);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url.$params);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);

return response()->json($result);`

```

**Screenshots (If applicable)**

**Additional Info**  
Note that I tried immediately the refresh token right after I got the access\_token. Can someone tell me why this is happening?

Hey @ronald.b,

I think you had a copy / paste error.

All the refresh tokens start with an `e`.

 ![6db31ba57f6382bf8b28ce7d16b2ca55920bce80](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/9/9fc217dadc99d22896bc8e9fec0fed1e82842129.png)

Double check you are pasting in the full refresh token and try again. 🙂

Thanks,  
Tommy
