rest_request_after_callbacks filter-hookWP 4.7.0

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 rest_send_allow_header().

Usage

add_filter( 'rest_request_after_callbacks', 'wp_kama_rest_request_after_callbacks_filter', 10, 3 );
