Adding a booking event webhook gives the hotel the possibility of receiving booking details in JSON format through a URL.

Note: This requires some basic knowledge about how to use a webhook. You might want to consult your web developer if you need any assistance.

A booking event webhook sends out a callback to a given URL and is triggered each time a booking is created, modified or cancelled.

The booking event webhook feature is triggered from:

  • The Sirvoy Booking Engine
  • The Review booking form
  • Sales Channel bookings

It can be activated in Settings -> Your account -> Booking Event Webhook.

The receiving server has to respond with response code 200 OK, otherwise , the call will be retried every 30 minutes up to 3 times. We only support HTTPS using TLS version 1.2 and up to ensure privacy and confidentiality. The HTTPS certificate also needs to be valid, otherwise , no data will be sent. The booking data is sent as a POST with the JSON as the request body.

Please also make sure your server will respond to HTTP GET requests with 200 OK. This is used as a health check that is called every now and then to make sure your endpoint is active. But no data will ever be pushed to you using HTTP GET.

The webhook callbacks will be made from the below IP-ranges. If you want to restrict traffic to your server, all of the below ranges need to be permitted in your firewall:

  • 34.243.166.60
  • 52.18.11.99
  • 63.34.80.48
  • 54.194.0.85
  • 2a05:d018:e34:5300::/56

The servers making the callbacks are dual-stack having both ipv4 and ipv6 connectivity. If you add both ipv4 and ipv6 addresses to your domain name , the webhook callback will be made to the server that is the first to respond.

Below are some examples of the JSON format generated data when a new booking is created:

This is how it can look after a cash receipt is created and a payment is moved to an invoice – the payments and the invoices that this booking has is also included in the webhook callback. Any other change also results in a webhook callback with the data , and this is how the booking event webhook in this example looks now:
