Hi Team

I am using zoom for the first time for integration and need the authorization code as a response of below endpoint.

Endpoint I am hitting : “[https://zoom.us/oauth/authorize?response\_type=code&redirect\_uri=https://login.salesforce.com&client\_id=Removed](https://zoom.us/oauth/authorize?response_type=code&redirect_uri=https://login.salesforce.com&client_id=Removed)”

In response I get : “System.HttpResponse[Status=Found, StatusCode=302]”

There is no authorization code returned in the response so how do we get it for backend APIs?

Note: If I paste the above endpoint in the browser, I get redirected to the redirect uri with the authorization code in the URL but I need it in the backend as a response of above end point.

Code:

Http h = new Http();  
HttpRequest req = new HttpRequest();  
req.setMethod(‘POST’);  
req.setEndpoint(‘[https://zoom.us/oauth/authorize?response\_type=code&redirect\_uri=https://login.salesforce.com&client\_id=Removed](https://zoom.us/oauth/authorize?response_type=code&redirect_uri=https://login.salesforce.com&client_id=Removed)’);  
HttpResponse hresp = h.send(req);  
System.debug(‘hresp2’+hresp);

@developer9 In order to get the code, someone needs to click on the URL manually. Can you confirm if this is happening?
