WP_HTTP_Response|WP_Error $response, array $handler, WP_REST_Request $request )
Filters the response immediately after executing any REST API callbacks.
Allows plugins to perform any needed cleanup, for example, to undo changes made during the ‘rest_request_before_callbacks’ filter.
Note that this filter will not be called for requests that fail to authenticate or match to a registered route.
Note that an endpoint’s
permission_callback can still be called after this filter – see
