Affirm

Affirm is a buy-now-pay-later (BNPL) provider that lets shoppers split a purchase into scheduled instalments at checkout, with the financing decision and repayment handled entirely by Affirm. It is one of the largest BNPL providers in North America, and is most commonly used for higher-value purchases where customers benefit from spreading the cost over time. Offering Affirm can lift conversion and average order value while the merchant is paid up front and Affirm carries the repayment risk. The connection to Affirm uses API credentials.
