Receive status updates from Access Worldpay by setting up a webhook.

What is a webhook?

Access Worldpay webhooks provide you with real-time information about the status of your requests. Setting up a webhook means you automatically receive updates when there is a status change with your request.

Event acknowledgement

Respond with a HTTP(S) response code 200 to confirm you've received the event.

Warning: Not acknowledging can cause delays (or loss) of subsequent events in the queue.

  • If a 200 event confirmation response is not received within 10 seconds, we retry the event until the confirmation is received.
  • Retry intervals increase based on the number of attempts, the time intervals increase starting 15 minutes to 2 hours per event.
  • The retry mechanism stops re-sending each event after either; an acknowledgement (200) is received, or after one week of attempting to send the event.
