Webhooks - Chobble Tickets

How to set one up

Each listing has a webhook address field. Enter the address of a service set up to receive the message, such as a Zapier or n8n trigger, and save the listing. To use one address for every listing, set it on the listing defaults page instead.

When a booking is made, Chobble Tickets sends a POST request with a JSON body to that address. Bookings made online and bookings an admin adds by hand both send one, and a source field says which it was.

What the message contains

Each message carries the buyer's name, email, phone, address and special instructions, the amount paid, any balance still owed, the currency, the payment reference and a link to the ticket. A tickets list gives each listing booked, with its name, date, quantity and unit price. Amounts are in pence, so 1500 means £15.00.

{
  "notification_type": "registration.completed",
  "source": "public",
  "name": "Alice Smith",
  "email": "alice@example.com",
  "price_paid": 3000,
  "amount_owed": 0,
  "currency": "GBP",
  "ticket_url": "https://tickets.example.com/t/A1B2C3D4E5",
  "tickets": [
    {
      "listing_name": "Summer Workshop",
      "date": "2025-08-20",
      "quantity": 2,
      "unit_price": 1500
    }
  ]
}

This is a shortened copy of the example in the published source. A test compares that example with the real message, so the two cannot drift apart. The admin guide inside each site shows the full version.

Orders for several listings

An order covering several listings sends one combined message to each different webhook address involved, rather than one per listing. If a single order would send to more than 16 different addresses, none are sent.

Limits

Chobble Tickets tries each delivery once and waits up to 10 seconds for a reply. A failed delivery does not stop the booking. It is recorded in the activity log, and you can re-send the notification from the attendee's page. Messages are not signed, so the receiving service cannot prove a message came from your site. The address must be a public https:// address.
