If you need a quick answer, a standard HaiPay integration usually moves through five stages: account setup, review, technical configuration, API testing, and go-live notification. HaiPay aims to provide secure and convenient overseas localized payment services and international credit card payment services, including services like collections(pay in), disbursements(pay out), and more. To ensure smooth integration, this document provides the standardized HaiPay product integration process.
