| Filter | Argument(s) |
|-----------|-----------|
| acf/rest_api/id | mixed ( string, integer, boolean ) **$id** string **$type** string **$controller** |
| acf/rest_api/key | string **$key** WP_REST_Request **$request** string **$type** |

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' );
} );
```

| acf/rest_api/types | array **$types** |
| acf/rest_api/default_rest_base | boolean **$default** string **$type** |
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`
```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.
```PHP
// 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' );
```
Editing the fields
====
The fields should be sent into the key `fields`.
**Action:** http://localhost/wp-json/acf/v3/posts/1
```HTML
Site:
Save
```
**Action:** http://localhost/wp-json/wp/v2/posts/1
```HTML
Title:
ACF
Site:
Save
```
Use the filter `acf/rest_api/key` to change the key `fields`.
```PHP
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`
```HTML
Site:
Save
```
