What it's for

Adding an endpoint to the WordPress REST API needs register_rest_route with a namespace, a route and the permission_callback (too often forgotten). Here you get the correct structure, with permissions already in place.

Frequently asked questions

›Why does permission_callback matter?

Because without it the endpoint is public and WordPress shows a warning. Defining it (even just __return_true if it's intentionally public) is required for a correct registration.
