Map<String, Object> meetingDetails = new Map<String, Object>{
    'topic' => appointment.Subject__c,
    'type' => 2,

How recently did you request that access token? The token lifetime should be disclosed when you receive it, and it might expire after 1 hour. Basically, I’m wondering what `ZoomMeetingScheduler.getAccessToken()` does in your code snippet — perhaps it’s using a previously-retrieved token without checking for its expiration.

Thanks for replying Christopher  
In the same transaction i m retrieving and using the token.

Zoom access tokens generated through OAuth 2.0 expire **1 hour (3600 seconds)** after they are issued but i am using immediately.

Also i have given all possible Scope. But no solution

Here is snippet written in Salesforce

public static String getAccessToken() {  
String clientId = ‘CLIENT\_ID’;  
String clientSecret = ‘CLIENT\_SECRET’;  
String credentials = clientId + ‘:’ + clientSecret;  
String encodedCredentials = EncodingUtil.base64Encode(Blob.valueOf(credentials));

```
    HttpRequest req = new HttpRequest();
    req.setEndpoint('https://zoom.us/oauth/token');
    req.setMethod('POST');
    req.setHeader('Authorization', 'Basic ' + encodedCredentials);
    req.setHeader('Content-Type', 'application/x-www-form-urlencoded');
    req.setBody('grant_type=client_credentials');

    Http http = new Http();
    HttpResponse res = http.send(req);

    if (res.getStatusCode() == 200) {
        Map<String, Object> responseBody = (Map<String, Object>) JSON.deserializeUntyped(res.getBody());
        return (String) responseBody.get('access_token');
    } else {
        System.debug('Failed to get access token: ' + res.getBody());
        throw new CalloutException('Error: Unable to fetch access token.');
    }
}

```

You might try appending `&account_id=<your account id>` to the above line. Additionally, if that doesn’t solve it, keep the account id addition but change the grant type to “account\_credentials”
