Hey all,

As the title suggests, I'm trying to set up an application that makes GET requests to my CRM. But I'm having issues getting past the OAuth token generation. I have no issues navigating to the authentication URL to grab the grant token, but once I've got the token, my application cannot POST to the auth URL to get the Access Token. I get this error:

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Shouldn't adding my client domain to the developer console alleviate this issue? Not sure how to solve this.
