NOTIFY_ADDRESS (type=4) When a user’s deposit address is changed in WaaS, the system notifies the merchant of the address change through this callback. The merchant must immediately update the user’s deposit address in their own system to ensure that subsequent deposits use the latest valid address.
System Behavior Explanation: WaaS may change user deposit addresses in the following situations:
  • Security policy requirements (e.g., regular address rotation)
  • Technical architecture adjustments (e.g., migration to new address pools)
  • Risk management needs (e.g., old address marked as risky)

​
