NOTIFY_NOT_ENOUGH_MONEY (type=6) When a withdrawal operation temporarily fails due to insufficient hot wallet balance, WaaS notifies the merchant through this callback. This is a temporary failure state. After the merchant replenishes the hot wallet balance, this withdrawal order will automatically retry.

​
Key Points

  1. Temporary Failure: Withdrawal operation not yet successful but recoverable
  2. Funds Remain Frozen: User funds remain frozen for subsequent retry
  3. Next Steps: After merchant replenishes hot wallet balance, WaaS automatically retries this withdrawal order

​
Request Parameters

The request sent by WaaS is an RSA-encrypted Base64 string. Merchants need to decrypt to obtain business parameters:
