A task force of the Web Payments Working Group has taken on the action of documenting the real-life payment flows for different methods of payment. Questions? Contact @mattsaxon.

Objectives

  • Verify whether and how the proposals support flows in use in real life
  • Identify any enhancements to the proposed flows or API to meet real life needs

Approach

  • Identify a set of payments flow types that should be modelled - Complete
  • Document the real-life flows currently in use in the wild - Complete
  • Map these flows to proposed future flows for the WG specification proposals - In Progress
  • Align these flows to ISO 20022 flows
  • Identity key pieces of data that must be passed to achieve a robust payment transaction (including support for subsequent settlement/disputes etc.)
  • Evaluate the resultant flows and provide recommendation/feedback to the WG
  • Initiate process to submit target flows and messages to ISO 20022
