Hi @dealmoney , I have seen this with developers attempting to use Server-to-Server OAuth incorrectly:

We are getting below error while creating meeting by using sever to server auth token.

Error: data: { reason: ‘Bad Request’, error: ‘invalid\_request’ }

Our meeting Creation Funtion:  
async function createZoomMeeting(accessToken) {  
try {  
const meetingData = {  
topic: ‘Sample Meeting’,  
type: 2, // 2 for scheduled meeting  
};

```
const response = await axios.post(
  'https://api.zoom.us/v2/users/'+'test@gmail.com'+'/meetings',
  meetingData,
  {
    headers: {
      Authorization: `Bearer ${accessToken}`,
    },
  }
);
  console.log("meetingssssssss",response);
return response.data;

```

} catch (error) {  
console.error(‘Error creating Zoom meeting:’, error);  
throw error;  
}  
}

HI @dealmoney ,

Can you confirm you have a valid token?

With a valid S2S token, can you successfully make the request in Postman? [Postman](https://www.postman.com/zoom-developer/workspace/zoom-public-workspace/request/22097587-9cab327f-7634-44af-9ee0-1b49f6a6572f)
