Filters

Basic example of how to use the filters, in this case I will set a new permission to get the fields

add_filter( 'acf/rest_api/item_permissions/get', function( $permission ) {
  return current_user_can( 'edit_posts' );
} );

Deprecated filters

Request API version

See below how to select the Request API Version.

1. Open the plugins page;
2. Click the settings link under the pluing name ( ACF to REST API );
3. Select your version in the ACF to REST API session;
4. Click in the button Save changes.

The other alternative is to define the constant ACF_TO_REST_API_REQUEST_VERSION in your wp-config.php

define( 'ACF_TO_REST_API_REQUEST_VERSION', 2 );

Field Settings

In this version is possible to configure the field options via admin.

The options are enabled using the filters below, by default theses options are disabled.

// Enable the option show in rest
add_filter( 'acf/rest_api/field_settings/show_in_rest', '__return_true' );

// Enable the option edit in rest
add_filter( 'acf/rest_api/field_settings/edit_in_rest', '__return_true' );

After you activate the filters, all your fields should show these options:

Editing the fields

The fields should be sent into the key fields.

Action: http://localhost/wp-json/acf/v3/posts/1

<form action="http://localhost/wp-json/acf/v3/posts/1" method="POST">
  <?php 
    // https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/
    wp_nonce_field( 'wp_rest' ); 
  ?>
  <label>Site: <input type="text" name="fields[site]"></label>
  <button type="submit">Save</button>
</form>

Action: http://localhost/wp-json/wp/v2/posts/1

<form action="http://localhost/wp-json/wp/v2/posts/1" method="POST">
  <?php 
    // https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/
    wp_nonce_field( 'wp_rest' ); 
  ?>
  <label>Title: <input type="text" name="title"></label>
  <h3>ACF</h3>
  <label>Site: <input type="text" name="fields[site]"></label>
  <button type="submit">Save</button>
</form>

Use the filter acf/rest_api/key to change the key fields.

add_filter( 'acf/rest_api/key', function( $key, $request, $type ) {
  return 'acf_fields';
}, 10, 3 );

Now, the fields should be sent into the key acf_fields

<form action="http://localhost/wp-json/acf/v3/posts/1" method="POST">
  <?php 
    // https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/
    wp_nonce_field( 'wp_rest' ); 
  ?>
  <label>Site: <input type="text" name="acf_fields[site]"></label>
  <button type="submit">Save</button>
</form>
