About Square
A payment and business management platform for merchants and developers.
Square provides APIs for accepting payments, managing customers, products, inventory, employees, and orders. It is used by businesses that need to run retail, restaurant, or service operations, and by developers building applications on top of Square's commerce infrastructure.
Where to start
Obtain an access token from the Square Developer Dashboard, then authenticate your API client with that token to start making calls — a common first step is creating a payment or retrieving a location.
