Overview

A high-level overview of the Flex Embedded Checkout integration and system design.

Flex Embedded Checkout​

A customer initiates the checkout experience by clicking the Pay with Flex button embedded in their payment portal. The user is redirected to a custom Flex experience that walks them through the checkout flow. Flex confirms the details and processes the payment, redirecting the user to a success or failure callback as applicable.

Split Payment Button

System Design​

Flex needs 3 APIs from the partner in order to complete the full split payment flow.

  • Fetch User Data
  • Fetch Bill Data
  • Create Payment
