Creating a Webhook Subscription #

A webhook is a means of notifying a third-party application of the occurrence of an event with some relevant information. In the Dwolla API, webhooks are currently triggered by the following resources:

  • Customers
  • Documents
  • Funding Sources
  • Transfers
  • Mass Payments

Each webhook sent by the Dwolla API contains an Event with _links to: the associated resource, account associated with the event, and the customer associated with the event (if applicable). It is important to note that a single API request can trigger multiple webhooks to be fired, e.g. initiating a transfer from an Account to Customer can create the events transfer_created and customer_transfer_created.

Webhooks are sent asynchronously and are not guaranteed to be delivered in order. We recommend that applications protect against duplicated events by making event processing idempotent.
