rest_request_before_callbacks WordPress Filter Hook
The rest_request_before_callbacks hook is called before the HTTP request is sent to the server. This hook allows you to modify the request before it is sent, or even cancel the request altogether. This hook is useful for making sure that the request contains all the necessary data, or for adding authentication information to the request.
apply_filters( 'rest_request_before_callbacks', WP_REST_Response|WP_HTTP_Response|WP_Error|mixed $response , array $handler , WP_REST_Request $request ) #
Filters the response before executing any REST API callbacks.
Description
Allows plugins to perform additional validation after a request is initialized and matched to a registered route, but before it is executed.
Note that this filter will not be called for requests that fail to authenticate or match to a registered route.
