iyzico vs PayTR vs Param — which Turkish payment gateway should I pick?

All three are Magento-supported. The right pick depends on your volume + features needed:

• iyzico — Türkiye’s dominant PSP, acquired by PayU then spun out. Best documentation, most Magento community modules, fastest onboarding (1–3 days). Strong on installment plans (taksit), BIN-based routing, marketplace seller payouts. ~2.45% + ₺0.25 typical.
• PayTR — #2 Turkish PSP, sharper pricing for high-volume merchants, strong recurring/subscription billing, good Magento module. ~2.25% typical.
• Param — #3, good for niche use cases (NFC, QR-code in-store, B2B token-payment). Less Magento community traction.
• Stripe (TR) — supports Turkish merchants since 2024 but coverage is limited; CB scheme issues with some BIN ranges. Useful as a USD/EUR-secondary, not as your primary TR rail.

Our default for a new TR build is iyzico primary + PayTR secondary. Both support 3DS2 + installment plans (taksit) natively.
