    I’m trying to update a custom field, but when I run the route through POSTMAN it does not update the field. Creates a new record. The route is something like:
    $POST …wp/v2/posts/362/meta?key=servicos_status&value=pause

    Someone help me?

    Hi,

    Are you sure that your callback function gets called? Can you try to put debug code there, just to see if it is. I’ve had similar issues when I declared callback function incorrectly, e.g. 

    $defaults = array(
        'get_callback'    => test_callback(),
    );

    instead of:

    $defaults = array(
        'get_callback'    => array( $this, 'test_callback' ),
    );

    when used in class scope.

    Thanks

    Thanks man.. Yes.. look

    add_action( 'rest_api_init', function () {
    register_rest_field( array('servicos', 'posts'),
        'servico_status',
        array(
            'get_callback'    => 'get_field_servico_status',
            'update_callback' => 'slug_update_servicos',
            'schema' => array(
                'description' => 'My special field',
                'type' => 'string',
                'context' => array('view', 'edit')
            )
        )
    );
});
function get_field_servico_status( $post, $field_name, $request ) {
    return get_post_meta( $post[ 'id' ], $field_name, true );
}
function slug_update_servicos($value, $post, $field_name) {
    if (!$value || !is_string($value)) {
        return;
    }
    return update_post_meta($post->ID, $field_name, strip_tags($value));
}

    Are you sure that slug_update_servicos() gets the arguments you’re checking and using in it? Can you try to debug all of the arguments by printing their values into error_log, i.e.:

    error_log( print_r( $value, 1 ) );
error_log( print_r( $post, 1 ) );
error_log( print_r( $field_name, 1 ) );

    Related question:
    when a content is created, a HTTP 201 is returned and returned JSON contains the new data *including the custom field*.
    I don’t understand how the update_callback could define the value given to the returned custom field.
