Square is moving beyond the retail terminal thanks to a handful of new APIs meant to help companies accept payments in more places. The E-Commerce API and Register API target retailers large and small with a simple set of tools that integrate fully with Square's payment processing platform.
Square now has an E-commerce API that brings Square services to third party websites. Square is usually associated with its mobile credit card reader and complementary software. With the E-commerce API, merchants can use their own systems with all the benefit of Square's modern payment services.
