Webhook event triggers

Booking lifecycle events

When you create a Webhook subscription, you must define the set of events that will trigger POST messages to your URL endpoint. These events represent the booking lifecycle scenarios you wish to receive notifications about. Learn more about the event object sent in the Webhook data payload

Specific and composite booking event triggers

OnceHub provide two types of booking lifecycle event triggers: Specific and composite. Specific triggers are based on an individual booking event (e.g. a booking is scheduled, or a booking is canceled). The composite booking event trigger includes all of the booking lifecycle event triggers.

The following is a list of booking lifecycle event triggers that are available to you:

Specific booking event triggers
booking.scheduled
booking.rescheduled
booking.canceled_then_rescheduled
booking.canceled_reschedule_requested
booking.canceled
booking.completed
booking.no_show

Composite booking event triggers
booking (includes all of the specific booking event triggers listed above)

Booking scenarios - Automatic booking

The following summarizes the various booking scenarios that will send a data payload to your server, when you are using Automatic booking.

Scheduling:

You will receive a booking.scheduled event when a booking is scheduled by your Customer.

Rescheduling by the Customer:

You will receive a booking.rescheduled event when a Customer reschedules a booking with the same User.
You will receive a booking.canceled_then_rescheduled event when a Customer cancels a booking with one User, and reschedules a booking with a different User.

Rescheduling requested by the User:

You will receive a booking.canceled_reschedule_requested event when the User requests to reschedule.
You will receive a booking.rescheduled event when the Customer reschedules a booking following the User's request to reschedule.

Canceling:

You will receive a booking.canceled event when a booking is canceled by either the Customer or the User.

Booking scenarios - Booking with approval

The following summarizes the various booking scenarios that will send a data payload to your server, when you are using Booking with approval.

Booking requested by the Customer:

You will not receive a notification at the time a booking is requested by the Customer.
You will receive a booking.scheduled event once the booking request is approved by the User.

Rescheduling requested by the Customer:

You will not receive a notification at the time a reschedule is requested by the Customer.
If the Customer requested to reschedule a booking with the same User, you will receive a booking.rescheduled event once the request is approved by the User.
If the Customer requested to reschedule a booking with a different User, you will receive a booking.canceled_then_rescheduled event once the request is approved by the User.

Rescheduling requested by the User:

You will receive a booking.canceled_reschedule_requested event when the User requests to reschedule.
You will not receive a notification at the time the Customer requests the rescheduled booking.
You will receive a booking.rescheduled event once the Customer's request is approved by the User.

Canceling:

You will receive a booking.canceled event when a booking is canceled by either the Customer or the User.

Additional booking scenarios

After the scheduled meeting time has passed:

You will receive a booking.completed event once the scheduled meeting end time has passed.
You will receive a booking.no_show event if the User sets the status of the completed meeting to No-show.

Receive notifications for all booking scenarios:

If you wish to receive data payloads for all of the booking scenarios described above, you can configure your Webhook subscription with the booking event trigger. This will cause POST messages to be sent to your URL endpoint whenever any of the above booking scenarios occur. Note: There is no booking event type - the specific event type (e.g. booking.scheduled, booking.canceled, etc.) that triggered the POST message will be specified in the data payload.

Session packages

Bookings scheduled as part of a Session package follow the same Webhook event trigger rules as single bookings.

Passing events to the Webhook object

To set the booking lifecycle event triggers for your Webhook subscription, you must pass an array of events in the body of the HTTP request. Learn more about configuring event triggers when you create a Webhook subscription

The following is an example of a Webhook object with two event triggers (booking.scheduled and booking.rescheduled) defined:

{
  "name": "New Webhook",
  "url": "https://my.url.endpoint/",
  "events": ["booking.scheduled", "booking.rescheduled"]
}
