What is Sipay (Payment Provider)?

Sipay is a Turkey-based payment institution that provides online payment acceptance, physical POS, payment links, marketplace payment flows, subscription collection, and digital wallet solutions. In e-commerce projects, it usually appears as a virtual POS or payment API integration.

What It Does in an Integration

When a store integrates Sipay, the checkout flow creates a payment request, the customer completes payment with a card or supported method, and Sipay returns the transaction result to the store. An order should not be treated as paid only because the browser redirected successfully; the backend should check the provider’s transaction status and, where available, server-side notifications.

What to Consider

Systems using Sipay need clear handling for commission and installment rules, refund and cancellation APIs, reconciliation reports, failed-payment codes, and webhook security. In marketplace models, sub-merchant identity, commission splitting, and settlement timing need separate design.

Virtual POS, payment gateway, and iyzico are related concepts when comparing payment infrastructure options. Provider choice depends on technical fit as well as reporting, support, and operational workflows.
