The Square API for point of sale enables you to build your own point-of-sale app on any iOS or Android device for use in your store or on the go. Our API will trigger an app switch that connects the customer from your app to the Square point-of-sale app to finalise the transaction.

The Square API for e-commerce enables you to accept credit and debit card payments online by integrating Square’s payment gateway on your custom website or leveraging our partnerships with website builders such as BigCommerce, Weebly, Ecwid, WooCommerce, Wix and Magento.
