For an ecommerce app, the usual best choice is Stripe.
Why Stripe fits your priorities:
- Low PCI burden: You can use Stripe Checkout or Elements so card data never touches your servers, which keeps you in the simplest PCI scope.
- Strong docs: Stripe is widely considered one of the best-documented payment APIs.
- Good developer experience: Clean APIs, solid SDKs, webhooks, test mode, and lots of examples.
- Ecommerce-friendly: Supports one-time payments, subscriptions, saved cards, refunds, disputes, tax, fraud tools, and more.
Good alternatives depending on your needs:
- Adyen — excellent for larger/global businesses, but usually more complex to integrate.
- Braintree — solid option, especially if you want PayPal support built in.
- Square — great if you also do in-person or omnichannel sales, less ideal for some global ecommerce setups.
If you want the simplest recommendation:
- Use Stripe Checkout if you want the fastest path to launch with minimal PCI exposure.
- Use Stripe Elements if you want a more custom UI while still keeping PCI burden low.
If you tell me your stack, countries you sell in, and whether you need subscriptions or only one-time payments, I can suggest the best specific setup.
