Get sales data for a Square merchant, itemize payments, push orders to POS, and more
The Orders API is your one-stop shop for adding rich functionality to payments. You can itemize payments using custom line items or catalog objects, send orders to physical Point of Sale devices to be fulfilled, attach a customer to a payment, and more.
In addition, the Orders API lets you search through all of a merchant's past sales and returns itemization data, customer references, and other details from sales made via POS or online.
