I am having issues making calls to the contact center API endpoint. In the Zoom created app I am using to authenticate I have all of the necessary scopes added to use the contact center endpoint as well as OAuth authentication. Whenever I attempt to make a call to any endpoint in the contact center I get a response with a 401 error code and a status of false. However, I can make successful calls to the phone endpoint with no issues using the same app. I did realize that even though I have the contact center scopes added to my app, in the “works with” section it does not specify “Contact Center”. If I add any other scopes like phone or meetings I can see it reflected in that “works with” section, but nothing for contact center.

Currently I am just trying to use postman to model the API calls and here is an example of me trying to call the reports:

URL → GET [https://api.zoom.us/v2/contact\_center/analytics/historical/queues/metrics?channel\_types=voice](https://api.zoom.us/v2/contact_center/analytics/historical/queues/metrics?channel_types=voice)

Request Headers → Content\_Type application/json

Response →   
{  
“status”: false,  
“errorCode”: “401”  
}
