$contact_details = array(
    'Email'         => '',
    'Mobile Phone'  => '0404555555',
    'Name'          => 'Bob Jones'

$api = new Api($url, 'YOURAPIKEY');
$contact_id = $api->invokeMethod('subscribeContact', $list_id, $contact_details);
    "id": 1,
    "method": "subscribeContact",
    "params": [
            "Email": "",
            "Mobile Phone": "0404555555",
            "Name": "Bob Jones"
    "id": 1,
    "result": 32,
    "error": null


When a contact is successfully subscribed, the system will:

  • Trigger associated Subscribe Campaign Events or Autoresponders.
  • Send a notification message to each address in the on_register_address value for the List (see addList).

Use addContacts for adding multiple Contacts to a List.

The API does not check the mandatory value of List Fields when adding or editing Contacts.
