About this Product

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.

What you get

Custom-built iyzico gateway plugin installed and activated on your WordPress / WooCommerce site

Configuration of your live iyzico API key and secret in the WooCommerce Payments settings, with sandbox tested first

End-to-end checkout test on your theme covering taksit, 3DS, saved cards and a test refund

HPOS compatibility verification against your store's order storage setting

Short admin guide covering installment thresholds, sandbox/production toggle and refund handling

Source code of the plugin delivered to you, plus a defined post-launch support and bug-fix window

Who this is for

Turkish online retailer offering installments

A merchant whose customers expect to split card payments into taksit and who needs that option native in WooCommerce checkout in TRY.

Store owner migrating off a hosted cart

An owner moving to self-hosted WooCommerce who already uses iyzico and needs the same installment and 3DS experience rebuilt on WordPress.

Agency or developer building for a TR client

A WordPress agency that needs a tested, HPOS-ready iyzico gateway with clean hooks rather than spending sprint time wiring the API themselves.

Frequently Asked Questions about iyzico Payment Gateway for WooCommerce

How long does delivery take, since this isn't an instant download?

This is a build-to-order plugin. After purchase, ECOSIRE scopes your store (WooCommerce version, theme, checkout type, WPML/multisite), then builds, installs and tests it on your site. Typical delivery is a few business days; we confirm a firm lead time once we've reviewed your setup. You do not download it yourself from a marketplace.

What do I need to provide to get started?

Your iyzico merchant account with API key and secret (sandbox first, then live), admin access to your WordPress site, and details of your WooCommerce version, active theme and whether you use the block or classic checkout. If you run WPML or multisite, let us know up front so we scope it correctly.

Do I get ongoing support and updates after launch?

Yes. The build includes a defined post-launch support window for bug fixes and configuration help. Because iyzico's API and WooCommerce both evolve, we also offer ongoing maintenance to keep the gateway compatible with new WooCommerce releases, HPOS changes and iyzico API updates. You receive the source code, so you are never locked in.

Will it work with WooCommerce HPOS and the new block checkout?

The plugin is built HPOS-compatible — it declares support for High-Performance Order Storage (custom order tables). Block checkout support is part of the scoping conversation: if your store uses the checkout block, we build the gateway's block integration so installments and saved cards render correctly there as well as in classic checkout.

Can customers really choose installments (taksit), and is 3D Secure included?

Yes. At checkout the gateway calls iyzico's installment-info lookup against the card BIN and shows the available taksit options. 3D Secure is included: the payment redirects through iyzico's 3DS flow and returns to a registered WooCommerce callback endpoint that finalizes the order. Saved-card one-click reuses iyzico's stored card tokens for returning, logged-in customers.
