It looks like you are getting a 403 error when you make the REST Call.

The 403 error is being returned by the external site to tell you that you don’t have permission to access to the resource.

It may be expecting some authentication data such as a key in the header, but the documentation on the external site should say what it needs.

Hope this helps
