Build with Square payments APIs.
Square lets developers build an ecosystem for businesses to seamlessly accept payments online, in store, or on the go. With our Square payments APIs (e-commerce API and point-of-sale API), you can create customizable solutions that work for any size business.
With our e-commerce API, you can take payments with Square on your own website.
Plug into Square’s platform
Get all the benefits of Square right on your site: fast deposits, Dashboard reporting and help with handling chargebacks.
Square’s e-commerce API makes PCI compliance easy; customer credit card information never touches your website, so you don’t need to worry or complete a single checklist.
No need to fret about chasing down a payment or setting up your own billing system. Get paid quickly with Square’s billing system and subscription APIs.
With our point-of-sale API, you can build your own app for powering in-store or mobile payments, no matter how big or small your business may be.
Square’s hardware is at the leading edge of speed, security and affordability.
Easy integration for in-person payments
With less than ten lines of code, you’ll be ready to seamlessly integrate Square into your checkout process.
Your app doesn’t have to handle any payments information, which makes PCI compliance a non-event.
