Webhook’s former name was Callback API.
Virtual Call Center’s Webhook is a webhook service that is able to automatically send information via HTTP(S) requests to one of your servers when a specific event occurs in our system, such as a disposition setting, or a successful credit card payment.
Webhook makes an initial attempt to deliver an event’s details to your server. If it fails it subsequently retries until it succeeds or reaches a limit. For further information please read the Resending failed requests section.
