Webhooks

Webhooks

Webhooks are user-defined HTTP callbacks which create notifications by Zendesk events to destination systems. The Webhook API lets you manage webhooks and enable subscriptions to receive notifications about Zendesk events. You can use webhooks with triggers and automations to send a notification when a ticket is created or updated.

To specify a webhook notification as an action for a trigger or automation, use the action's notification_webhook field. This field's value is an array of two strings specifying the numeric ID of the webhook and the message body. Example:

{
  "actions": [
    {"field": "notification_webhook", "value": ["12345678", "Ticket {{ticket.id}} has been updated."]}
  ]
}

For more information, see Triggers or Automations.
