I am trying to connect to the API but i keep getting No 'Access-Control-Allow-Origin' error.
How do i add my domain to policy to allow to talk to the API?
You're trying to connect directly to the API from a browser that enforces CORS?
This means you are revealing your API secret key to the world. Very, very bad idea. The APIs must not be connected to directly from a browser. They're meant for server-to-server access.
