Delivery Webhook

Webhooks enable you to get updates on changes in the state of the ride without the need to poll the Gett API. If you only need to know about major state changes - such as when the passenger's driver has arrived, or when the passenger's receipt is ready - then it's better to set up a webhook.

What's a webhook?
A webhook is an endpoint that you set up on a publicly accessible server you control. After registering that endpoint with Gett, Gett will then make HTTP POST requests to it when certain events occur.
