A Checkout Session represents a Monime-hosted payment flow where customers complete purchases for a defined set of items.
It is designed for e-commerce and embedded payment scenarios where merchants want a simple, secure way to accept payments across multiple channels without building the payment UI themselves. Unlike direct API-based payments, a Checkout Session aggregates multiple payment methods — such as Mobile Money, Card, and Bank Transfers — and presents them in a unified checkout experience.

​
Use Cases

  • E-Commerce Cart Checkout
    A customer selects items in a cart. The merchant creates a Hosted Checkout Session, and Monime presents Mobile Money, Card, and Bank options in one unified flow.
  • Embedded SaaS Billing
    A SaaS platform embeds a Hosted Checkout Session to bill users. Customers pick their preferred channel (Card, MoMo, Bank), and once payment is confirmed, the SaaS receives checkout_session.completed.
  • QR or Link-Based Payment
    Merchants generate a checkout session link or QR code. Customers open the hosted page and choose any available payment method.
  • Fallback Across Methods
    If a user’s card payment fails, they can seamlessly retry with Mobile Money — all within the same checkout session.
