Which Square APIs are available in the UK?
The following payment APIs are available to sellers and developers in the UK:

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.
