How it works

When a customer selects Affirm as a payment option, the view expands and renders the following information in your site:

  • Value props: Highlights some of the benefits of paying with Affirm.
  • Learn more about Affirm: A learn more link that opens our educational modal.
  • Payment timelines: The timeline and amount for each payment.
