Payment Deduction Notification

Overview

This page documents webhook subscriptionOrderPaymentWebhook. The full schema, parameters, and examples are rendered from the linked OpenAPI or webhook definition above. After a subscription billing cycle completes, GatePay sends an asynchronous notification to the merchant-configured callback URL. Depending on the payment channel, bizType may be SUBSCRIPTION_PAYMENT (Web3 on-chain deduction) or ACCOUNT_AUTH_DEDUCTION (Gate account authorized deduction).

Notes

Use bizId, paymentOrderNo, or deductOrderNo for idempotency after parsing data.
Signature verification, retries, parsing data, and the success response are covered in Notifications Overview; see Security and Signature for signing rules.

When notifications are sent

GatePay sends a notification after each subscription billing cycle completes (success or failure)
If delivery fails, GatePay retries according to Notifications overview
Use Deduction order detail as a query fallback when needed
