# About the Payment Event API

The Payment Event API exposes a webhook that notifies your system when payment transactions are updated.

When you subscribe to the Payment Event webhook, Wix sends notifications to your endpoint whenever a transaction is created, updated, or refunded.

Notifications are sent for transaction lifecycle events including:
- New transactions created
- Transaction status changes
- Payment completions

**Note:** For refund notifications, listen to the [Refund Created](https://dev.wix.com/docs/api-reference/business-management/payments/refunds/refund-created.md) and [Refund Updated](https://dev.wix.com/docs/api-reference/business-management/payments/refunds/refund-updated.md) webhooks.
