Webhooks are HTTP notifications, dispatched to a specified URL when certain events are triggered.
For more information on the setup and configuration of Webhooks, see the general Webhooks section (under the Products menu).
When working with E-Mandates, the Mandate Signature Webhook notification is useful: this notification will let you know when your customer has signed a mandate.
Note that other Webhook notifications related to direct debit updates may also be useful once an e-mandate has been signed. For more details on those notifications, see the Webhooks section under Nuapay.
