Introduction

Outgoing webhooks allow you to receive real-time notifications about reservation events from your PMS. When a new integration account is created, Zepl automatically subscribes to webhooks on our end. We process these webhooks to update reservations, and listing information. By creating an outgoing webhook app, you can also receive webhooks from our system, to notify about changes made to reservations.

​
Supported Events

Currently, we support the following reservation events:

  • RESERVATION_CREATED: Triggered when a new reservation is created
  • RESERVATION_UPDATED: Triggered when an existing reservation is modified
  • RESERVATION_CANCELLED: Triggered when a reservation is cancelled

​
Getting Started

To start receiving webhook notifications, you will need to create an outgoing webhook app for each provider you want to receive reservation events from. This needs the following information:

  • The provider you want to receive reservation events from
  • The events you want to monitor (RESERVATION_CREATED, RESERVATION_UPDATED, RESERVATION_CANCELLED)
  • The URLs where you want to receive the notifications

​
Webhook Payload Structure

When an event occurs, Zepl will send a POST request to your configured URLs with a payload in the following format:

  "event": "RESERVATION_CREATED",
  "data": {

Considerations

  1. Always validate the webhook payload on your end
  2. Implement proper error handling for failed webhook deliveries
  3. Use HTTPS URLs for secure webhook delivery
