What are webhooks?
WebHooks allow you to notify a system that a specific event has occurred. When an application notifies an event via WebHook, other applications interested in the event do not need to poll to be aware of the event. This reduces the volume of messages between applications.
When does it make sense to use webhooks?
The use of Webhooks is worthwhile if, for example, an ERP system needs to know about the appointment or event booking in order to trigger further actions or to save the data about the booking.
