Cross-Origin Resource Sharing (CORS)

---

HTTP requests are launched on the client side, directly in your browser, the calls are cross domain.

You must allow Cross-Origin Resource Sharing (CORS) in your REST API. Example for CORS in php:

header('Access-Control-Allow-Origin: *');

You also need to authorize headers if you need to send headers in yours requests:

header('Access-Control-Allow-Headers: *');
