Event objects can be sent directly to an endpoint on your server. Webhooks are configured in your account settings under More - Advanced - API Settings - Webhook. If you provide a URL and credentials for Basic Auth, Keycafe will POST individual notifications to your server in the same format as they are returned from the Retrieve Event endpoint.
There are two event types supported: PICKUP and DROPOFF.
A 200 status code returned from your server will be interpreted as a success. Any other status code will be interpreted as a failure, and Keycafe will try a maximum of 10 times (using exponential backoff) to deliver a notification. Note that the order in which the notifications arrive is not guaranteed.
