Order Transactions

These webhook events are triggered based on the overall lifecycle of a Payment Order. Merchants must strictly listen to order update events as the authoritative trigger for fulfilling orders or releasing services.

🔔 Event Types

Event Identifier	Trigger Condition & Business Meaning	Actionable Advice
`pay.transaction`	Order Created: Triggered when a payment order is successfully created in the system. The status is typically `pending`.	Use for logging or reconciliation only. Do not fulfill the order.
`pay.transaction.update`	Order Updated: Triggered whenever there is a change in the order's status, confirmed amount, etc.	🌟 Fulfillment Trigger: Listen to this event. When the `status` field in the payload changes to `completed`, execute your fulfillment logic.

📦 Payload Example

When an event occurs, DogPay sends a POST request to your configured webhook endpoint. Below is the complete payload example of a pay.transaction.update event when the order is completed:

⚠️
Idempotency Note
Please use event_id or the order's idNo to ensure idempotency. Always check if the order has already been fulfilled in your database before processing to prevent duplicate delivery caused by network retries.
