Notifications
Register the URL we call when one of your campaigns ends or your credit runs low.
📄️ Get your notification URL
Returns the URL currently registered for your account, or `null` if you are not subscribed.
📄️ Register or replace your notification URL
Registers the URL we call. A new registration replaces the previous one; a null or empty `webhookUrl` unsubscribes you.
📄️ Unsubscribe from notifications
Removes your notification URL. Equivalent to a `PUT` with a null `webhookUrl`.
