In order to fix CORS, you need to make sure that the API is sending proper headers (Access-Control-Allow-*).

The same-origin policy fights one of the most common cyber attacks out there: cross-site request forgery. In this maneuver, a malicious website attempts to take advantage of the browser’s cookie storage system.
