Afterpay is officially available to developers in the U.S. and AU! 
Afterpay is a global leader in the “buy now, pay later” (BNPL) space and enables customers to pay for transactions in four interest-free installments.
Before today, developers could build separate integrations with Square and Afterpay APIs. Now, developers can add a few lines of code within the Square Web Payments SDK to enable Afterpay in their online checkout flow. This single integration decreases required developer resources and reduces maintenance costs. Plus, all Square and Afterpay funds flow into sellers’ Square accounts for simpler cash flow management.
