iyzico Payment Gateway for WooCommerce is a build-to-order plugin that connects your WooCommerce checkout directly to the iyzico payment API, purpose-built for Turkish merchants who need card installments (taksit) alongside standard card payments in Turkish Lira (TRY).

This is not an instant marketplace download. After purchase, ECOSIRE builds, installs and configures the plugin on your own WordPress site — wiring your live iyzico API key and secret into the WooCommerce Payments settings (wp-admin), registering the gateway via the woocommerce_payment_gateways filter, and testing the full flow on your theme and checkout before go-live.

The gateway integrates the way a proper WooCommerce extension should: it extends WC_Payment_Gateway, hooks into woocommerce_api_* for the iyzico callback/return URL, and is built HPOS-compatible (declares support for WooCommerce High-Performance Order Storage / custom order tables) so it runs cleanly on modern stores. Order status transitions, refunds and 3D Secure redirects are handled through standard WooCommerce order actions and the iyzico retrieve/refund endpoints.

Core capabilities include taksit installment selection at checkout (driven by iyzico's installment-info lookup per BIN), 3DS-compliant card authentication, one-click saved cards via iyzico's card-storage tokens, TRY settlement with refunds issued back through the API, and access to iyzico's fraud and risk scoring on each transaction.

Because every store is different, the build is scoped to your WooCommerce version, theme, checkout type (classic shortcode or block checkout), and whether you run WPML or multisite. ECOSIRE delivers it tested, documented and supported — so you get a gateway tailored to your store, not a generic plugin you fight with.
