Getting Started with Payment APIs
Compare Stripe, Adyen, and other payment APIs to pick the right processor for your stack.
Choosing a payment API is one of the most consequential decisions for any fintech product. The right provider can accelerate your time to market; the wrong one can mean painful migrations and lost revenue.
Stripe remains the most developer-friendly option, with exhaustive documentation, SDKs in every major language, and a powerful dashboard. Its strength is simplicity — one API for payments, subscriptions, marketplaces, and more.
Adyen targets larger merchants with multi-acquiring, global processing, and unified commerce. If you need to optimize authorization rates across dozens of payment methods worldwide, Adyen's platform gives you the control you need.
For startups and SMBs, Paddle and Lemon Squeezy offer merchant-of-record services that handle tax compliance and invoicing, letting you focus on your product rather than billing operations.
When evaluating, consider your geographic markets, required payment methods, fraud tooling, and whether you need a full-stack solution or a more modular approach.
