iyzico Gateway for Magento 2 is a custom-built payment integration that connects your Magento Open Source or Adobe Commerce checkout to iyzico, Turkey's leading payment gateway. This is not an instant Adobe Commerce Marketplace download — ECOSIRE builds the extension to fit your store's Magento version, theme and checkout flow, installs it under app/code/Ecosire/Iyzico, and supports it afterward.

The integration is built the Magento way: a real payment method module that implements Magento's payment service contracts and Gateway Command pattern (Authorize, Capture, Refund, Void), wired through di.xml, with configuration exposed via system.xml under Stores → Configuration → Sales → Payment Methods and protected by admin ACL. Sensitive credentials (iyzico API key and secret) are stored encrypted in core_config_data.

For Turkish merchants, the headline capability is installments (taksit). We call iyzico's installment-info endpoint using the customer's card BIN and render the available installment plans directly in checkout, so shoppers see real per-bank taksit options before they pay. Checkout runs through iyzico's hosted / iframe (CheckoutForm) flow with 3D Secure authentication, keeping card data off your servers and easing PCI scope.

Order lifecycle is fully wired into Magento: successful authorizations create invoices, refunds and partial refunds are issued from the admin Credit Memo screen straight to iyzico's refund API, and gateway callbacks are verified server-side before any order state changes. We use observers/plugins rather than core edits, so your store stays upgrade-safe.

Every build includes installation on your environment, a sandbox-to-production cutover, and a support window. Because it's bespoke, we can extend it — REST/GraphQL exposure, headless (PWA Studio) checkout, marketplace split payments — on request.
