NOTIFY_NOT_ENOUGH_HOT_MONEY (type=7) When a withdrawal operation temporarily fails due to insufficient main coin balance in the hot wallet (insufficient Gas), WaaS notifies the merchant through this callback. This is a temporary failure state. After the merchant replenishes the main coin balance in the hot wallet, this withdrawal order will automatically retry.

​
Key Points

  1. Insufficient Gas Fees: Hot wallet lacks sufficient main coin to pay network transaction fees
  2. Funds Remain Frozen: User withdrawal funds remain frozen
  3. Next Steps: After replenishing main coin balance in hot wallet, WaaS automatically retries withdrawal

​
Request Parameters

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

​
Response Parameters
