CoinVoyage webhook event types and payload reference

CoinVoyage emits a webhook event at each stage of the PayOrder lifecycle. For every event you subscribe to, CoinVoyage delivers a POST request to your endpoint containing a JSON payload that describes what changed. This page covers every event type, the payload structures you can expect, and a full example for each.

There is a naming difference between the identifiers you use when subscribing to events and the type field in the delivered payload. Subscription identifiers use uppercase ORDER_* format. The type field in the JSON payload uses lowercase payorder_* format. For example, subscribing to ORDER_COMPLETED results in payloads where "type": "payorder_completed".

`ORDER_CREATED`	`payorder_created`	A new PayOrder was created.
`ORDER_AWAITING_PAYMENT`	`payorder_started`	The PayOrder is ready and awaiting payment from the user.
