  title: Temenos BNPL Generate Offer And Accept Into Loan
  summary: Generate a buy-now-pay-later offer for a purchase and accept it into an active loan.
  description: >-
    Buy-now-pay-later checkout flow in Temenos. The workflow generates a BNPL
    credit offer for a customer's purchase using Explainable AI decisioning,
    accepts the first returned offer to create the loan and trigger merchant
    settlement, and then reads the resulting loan back to confirm its
    installment schedule and status. Every step inlines its request so the
    chain is self-describing.
