Wordpress Rest API - Custom Fields

I have created a custom post type in Wordpress and exposed it to rest API. I have also added custom fields to this post using the ACF plugin.

In my themes function.php I have registered these fields in the response and I can see them when I make a get request.

register_rest_field('auto', 'specs', array('get_callback' => 'get_autos_specs_for_api'));

The problem is that when I send a post request, wordpress doesn't recognize these fields. It creates a new post with the title and all the extra fields are empty.

For me what did the trick was to hook yourself to the rest prepare post and then add your fields to the array, then return the response object.

function slug_add_data($response, $post) {

    $response->data['latitud'] = get_field('latitud', $response->data['id']);
    $response->data['longitud'] = get_field('longitud', $response->data['id']);

    return $response;
}

add_filter('rest_prepare_post', 'slug_add_data', 10, 3);

Instead of using the custom code, Use the out of the box solution for accessing ACF fields into the Rest API.
Plugin URL: https://github.com/airesvsg/acf-to-rest-api

Add the filter as below:

//Filter to to get acf field within acf field for relational field set
add_filter( 'acf/rest_api/<custom_posttype>/get_fields', function( $data ) {
    if ( ! empty( $data ) ) {
        array_walk_recursive( $data, 'get_fields_recursive' );
    }

    return $data;
} );

You will get the ACF fields object inside the default WordPress Rest API response it's self, If all configuration are correct.

Let me know if any helps needed!

Try that solution: 

function wp_api_encode_acf($data,$post,$context){
    $data['meta'] = array_merge($data['meta'],get_fields($post['ID']));
    return $data;
}

if( function_exists('get_fields') ){
    add_filter('json_prepare_post', 'wp_api_encode_acf', 10, 3);
}
