CORS

Cross-Origin Resource Sharing (CORS ) is an HTTP-header based mechanism that allows a server to indicate any origins (domain, scheme, or port) other than its own from which a browser should permit loading resources.

The same-origin security policy  forbids cross-origin access to resources. But CORS gives web servers the ability to say they want to opt into allowing cross-origin access to their resources.

Configuration

Unless specified otherwise, most API services support CORS. To define the origins that are acceptable, create an OAuth client that matches the origin PageSeeder should accept.

For example, to supports cross-origin request from an app at https://app.example.net , you need to register an OAuth client and set its URI as https://app.example.net.
