Usage

To use the filter, add the following line to your code:

Examples

Add a new service

This example adds a new custom service to the “Email Service” setting:

add_filter('gform_notification_services', 'add_notification_service');
function add_notification_service($services) {
    $services['the_service_name'] = array(
        'label' => esc_html__('Your Custom Service', 'gravityforms'),
        'image' => 'http://someurl.com/image.svg'
    );
    return $services;
}

Place this code in the functions.php file of your active theme.

Note: Additional code is necessary to handle having the service actually send the notification email since this hook only makes the choice available to the user for selection when configuring their notifications.
