While the docs state: Note that the API cannot prevent you from changing responses, but the code is structured to strongly discourage this. Internally, field registration is powered by filters, and these can be used if you absolutely have no other choice. there IS another choice for most cases, namely: custom endpoints/routes. You can even … Read more
The get_callback part is generated within the WP_REST_Controller::add_additional_fields_to_object() method with: $object[ $field_name ] = call_user_func( $field_options[‘get_callback’], $object, $field_name, $request, $this->get_object_type() ); That means the callback has four input arguments: ‘get_callback’ => function ( $object, $field_name, $request, $object_type ) { // … } and for the requested category object, we can get the term id with: … Read more
You cannot get over that limit of 100 posts per requests in WordPress for default requests. One way to still retrieve all posts would be to query that interface until you have all posts. Another would be a custom endpoint. If you can, I suggest creating your own REST endpoint. This will already work and … Read more
So it turns out in WP 4.7 the Filter argument for any post endpoint was removed. You can add it but installing this plugin on the site that you are trying to get posts from. https://github.com/WP-API/rest-filter

I delete wpApiSettings.nonce at the top of my app.js, perhaps not an ideal solution but it works.
I Resolved: function job_listings_to_api( $args, $post_type ) { if ( ‘job_listing’ === $post_type ) { $args[‘show_in_rest’] = true; } return $args; } add_filter( ‘register_post_type_args’, ‘job_listings_to_api’, 10, 2 ); add_action( ‘rest_api_init’, ‘create_api_posts_meta_field’ ); function create_api_posts_meta_field() { register_rest_field( ‘job_listing’, ‘_date-start’, array( ‘get_callback’ => ‘get_post_meta_for_api’, ‘update_callback’ => ‘update_post_meta_for_api’, ) ); } function get_post_meta_for_api( $object, $field_name, $request ) { … Read more
Here’s an answer to question 1 that uses register_post_meta. It’s also the start of an answer to question 2 by use of the prepare_callback option in show_in_rest . add_action( ‘init’, ‘wpse_89033_register_custom_meta’ ); function wpse_89033_register_custom_meta() { $post_types = [ ‘post’, ‘page’, ‘attachment’, ]; foreach ( $post_types as $post_type ) { register_post_meta( $post_type, ‘_custom_key’, array( ‘type’ => … Read more
I was able to solve the problem by adding a custom route. Although i had to do the same process in php by first querying all available terms of the type and then exclude them from the query. $available_terms = array_map( function ( $term ) { return $term->term_id; }, get_terms( ‘lagerboxen_kategorie’ ) ); return get_posts( … Read more
