FAQ

  • A payment gateway API is the set of secure endpoints your code calls to authorize, capture, refund and reconcile payments, without handling raw card data yourself. HaiPay's REST API covers both pay-ins and payouts in one integration, with SDKs, webhooks and a sandbox.

  • Typical flow: create sandbox credentials, install the SDK or call the REST endpoints, build the payment request and webhook handlers, run test transactions, then switch to production keys. Hosted checkout or payment links need little to no code if you want to launch faster.

  • The API itself is usually free — providers charge per transaction, not for access. Your real costs are transaction fees plus engineering time, which depends on the integration depth: payment links and hosted checkout are near zero-code, full API integration takes the most effort.

  • Yes. HaiPay exposes global collection and global payout capabilities through the same API and account, including internal balance transfers between them — so funds collected from customers can fund supplier or creator payouts without leaving the platform.

  • Transactions are collected in the shopper's currency, and balances can be held, converted and settled across multiple currencies from one account. The API and dashboard give a unified view for reconciliation across markets.

  • Yes. HaiPay provides a sandbox with test credentials, simulated payment states and webhook events, so you can verify the full payment and payout lifecycle before going live.
