Payment Integration for E-Commerce: Stripe, iyzico and PayTR Guide

78 percent of online purchases in Turkey are made by credit card, and each additional step on the checkout page increases cart abandonment by 10 percent. Properly configured e-commerce payment integration both increases conversion rates and protects customer data. This guide covers API setup, security configuration, and testing for Stripe, iyzico, and PayTR.

Stripe: For International Sales

Stripe enables payment acceptance in over 135 countries. Its API documentation is excellent and integration is the fastest. However, direct Turkish Lira support is limited and commission rates are higher than local alternatives.

iyzico: For the Turkish Market

iyzico is Turkey's most widely used payment infrastructure. It offers installment support up to 12 months, marketplace payments, and easy integration with official plugins for WooCommerce, OpenCart, and Magento.

💡 Tip: Use tokenization on payment pages to avoid storing card data on your servers. Hosted payment forms from iyzico and Stripe significantly reduce your PCI DSS compliance burden.

Integration Process

Every payment provider offers sandbox (test) and production environments. Complete integration in sandbox first and verify with test cards. Never store API keys in source code — use environment variables (.env).

⚠️ Important: Before going live, always make a small real-card test payment. Sandbox and production API behaviors may differ.
