Hi,  
I am trying to generate access token by passing authorization code to the below api  
[https://zoom.us/oauth/token](https://zoom.us/oauth/token)  
but always getting below error  
{  
“reason”: “Invalid authorization code xxxxxxxx”,  
“error”: “invalid\_grant”  
}

Below is my node.js code to generate access token I am using node-fetch:

const url = `https://zoom.us/oauth/token?grant_type=authorization_code&code=${code}&&redirect_uri=${process.env.ZOOM_REDIRECT_URI}`;

```
const request = await fetch(url, { 
                                                                   method:'POST',
                                                                   headers: {
     'Content-Type': 'application/x-www-form-urlencoded',
     'Authorization' : 'Basic ' + Buffer.from( username+ ':' + password).toString('base64'),
 }
});

```

Here username and password are clientId and secret key, I have tried both with development credentials and production.
