Invocie Webhook Notification

CCPayment will post the webhook notification when the merchant receives the Invoice payment.

Webhook notification

There are three transaction statuses in the webhook notification under the field name “pay_status”. CCPayment will credit assets if the pay_status is “success”, which is the one and only status you should consider as the confirmation of the transaction. The other two pay_status, “pending” and “processing”, can not be regarded as the confirmation of the transaction.
