Frequently asked questions
Which payment gateway has the best authorization rates?
It varies by region, MCC, and issuer mix. Enterprise processors like Adyen and modern acquirers like Stripe excel with network tokens and smart retries. Always measure your auth rate by BIN/issuer.
Should I offer PayPal in 2025?
Yes, as a wallet alongside onsite cards. PayPal can lift conversion for new or cross‑border shoppers. Keep onsite cards or Shop Pay for the fastest flows.
What’s the fastest way to add Apple Pay and Google Pay?
Use your gateway’s native SDKs. Stripe, Adyen, Braintree, Checkout.com, and Square all provide wallet integrations with domain verification steps.
How do I stay PCI compliant on WooCommerce?
Use hosted fields or iFrames from your gateway, avoid handling raw PANs, and keep your platform and plugins updated. See PCI SSC.
Do I need 3D Secure (SCA) outside the EU/UK?
Not generally required, but 3DS can reduce fraud and chargebacks in risky segments. In the EU/UK, SCA is mandatory for most transactions. See SCA guidance.
Can I use multiple gateways?
Yes. Many brands run a primary gateway plus wallets; some add a secondary for failover or specific regions/methods. Route by BIN/geo when volume warrants.
How do I measure payment performance?
Track auth rate, soft vs hard declines, chargeback rate, checkout drop‑off, and revenue influenced. Pipe webhooks into your CRM dashboards.
How do fees compare between providers?
Fees vary by method, region, and volume. Do not guess—confirm on official pricing pages and model your actual mix.
What’s the best gateway for subscriptions?
Stripe and Braintree are strong for trials, proration, tax, and dunning. Evaluate your needs for upgrades, seats, and metered billing.
Are platform-native options worth it?
Yes. Shopify Payments and WooCommerce Payments deliver high‑fit UX and simpler ops if you are on those platforms.
