Adding Query Parameters
-
I am looking to retrieve a subset of the records for a custom post type based on a value in an ACF field. The application is to allow our mobile app developer to call my site’s REST API for conference sessions, but only the ones with a flag set.
Functionally, I’d like to just add the query param and value to the end of the url, like this:
https://www.immunology2023.org/wp-json/wp/v2/session?app_share=1I’ve seen the WordPress documentation for doing this, but it includes the creation of a new REST endpoint, and I want to add this query param to an existing endpoint generated by the WP REST API Controller plugin.
Any advice? Code samples welcome!
Thanks!

I have drafted my own code snippet, to no avail. I should mention that the field app_share is from ACF, although I don’t think that should affect registering it for query.
add_action('rest_api_init', function(){ register_rest_field('session', 'app_share', array( 'get_callback' => function($params){ return \get_post_meta($params['id'], 'app_share', true); } )); });
