rest_authentication_errors WordPress Filter Hook
The rest_authentication_errors hook is used to add authentication errors to the WordPress REST API. This hook is called when the user is not authenticated and returns an error.
apply_filters( 'rest_authentication_errors', WP_Error|null|true $errors ) #
Filters REST API authentication errors.
Description
This is used to pass a WP_Error from an authentication method back to the API.
Authentication methods should check first if they’re being used, as multiple authentication methods can be enabled on a site (cookies, HTTP basic auth, OAuth). If the authentication method hooked in is not actually being attempted, null should be returned to indicate another authentication method should check instead. Similarly, callbacks should ensure the value is null before checking for errors.
A WP_Error instance can be returned if an error occurs, and this should match the format used by API methods internally (that is, the status data should be used). A callback can return true to indicate that the authentication method was used, and it succeeded.
