Splitit

name: Splitit
description: >-
  Splitit is a credit card installment platform that enables merchants to offer
  shoppers the ability to split existing credit card purchases into monthly
  installments without requiring new credit applications, additional interest
  charges, or third-party redirects. The platform operates directly on shoppers'
  existing credit cards, leveraging available credit to create installment plans
  while merchants receive full payment upfront. Splitit provides REST APIs for
  installment plan creation, eligibility checking, refunds, chargebacks, and
  merchant onboarding, along with plugins for major e-commerce platforms.
