**Description**  
I am trying to test Zoom API functionality using Postman but I cant seem to get it working.  
I’ve followed instructions here:

> **[Using Postman to Test Zoom APIs - Postman - Guides - Documentation](https://marketplace.zoom.us/docs/guides/guides/postman/using-postman-to-test-zoom-apis)**
>
> Using Postman to Test Zoom APIs
> 
> To get started you will need to import the Zoom API collection from GitHub using the OpenAPI Specification. In the top ...

  
But Postman returns an error “This API only supports oAuth2 for authorization.”

**Error**  
{  
“code”: 124,  
“message”: “This API only supports oAuth2 for authorization.”  
}

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
Knowing the endpoint/s can help us to identify your issue faster. Please link the ones you need help/have a question with.

**Which Endpoint/s?**  
All endpoints tested return this error. I cannot authenticate.

Hey @darraghking,

Which endpoint is throwing that error? Can you share a screenshot?

Thanks,  
Tommy
