An HTTP POST message is used to push relevant booking or conversation data to the Webhook URL, and is triggered whenever the defined lifecycle event occurs. The data is sent as JSON key-value pairs (KVPs) to your receiving server when a booking lifecycle event occurs in your OnceHub account. For example, you can create a Webhook that sends customer details whenever a new booking is scheduled.

Managing your Webhooks

Webhook subscriptions can be created, deleted, and retrieved via the Webhooks API. You can also view and delete your Webhooks from the API Integration page

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.

Specific and composite event triggers

• Specific triggers are based on an individual event (e.g. a booking is scheduled, or a booking is canceled, or a conversation is closed).
• The composite booking event trigger includes all of the booking lifecycle event triggers.

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

Specific conversation event triggers
conversation.reached_out
conversation.started
conversation.closed
conversation.abandoned

Composite booking event triggers

Managing Webhook subscriptions via the API

Input parameters

When creating the webhook, you should provide

• a name
• a url for receiving POST messages
• an array of events in the request body.

You may specify specific booking lifecycle events you wish to subscribe to, or you can pass the booking event to trigger the POST payload message whenever any of the supported booking lifecycle events occurs.

Make sure that you pass the full URL. For security reasons, only HTTPS URLs are accepted.
