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

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
