What is Payment Gateway API?
Payment Gateway API helps build a payment system using smart contracts or virtual accounts. You can deploy a smart contract or issue a virtual account to receive a specific asset, and you receive a callback when the asset is deposited into the smart contract or virtual account. It also supports requests to withdraw assets, and the user receives the result as a callback.
Payment Gateway ACLs
Payment Gateway's deposit and withdrawal results are delivered to the user's server through callbacks. At this time, the user must allow permission by adding the IP below to the ACL to receive the callback.
