WPWG Plan 2019

Status

This is a draft document for discussion about plans from Q4 2019 through 2020.

This document does not include:

• ongoing discussion of feature enhancements for after PR API 1.0

Goals

1. Interoperability
2. Adoption
3. Rechartering

1. Interoperability Objectives

• Specifications
  • Payment Request 1.0 advances to Proposed Recommendation
  • SRC payment method advances to FPWD
• Payment Handlers
  • All major browsers add support for payment handlers (through PH API or other)
• Security
  • Web Authentication works for payments use cases

Other considerations:

• Do we need a 3DS module? Tokenization module?
• Privacy discussions (3DS and trust tokens) happening in the WPSIG.
• Do we need to spec JIT installation and skip-the-sheet at a high level for consistent UX?

Payment Request 1.0 advances to Proposed Recommendation

Note: At the 31 October 2019 WPWG teleconference we discussed delaying the advance to Proposed Recommendation to get more adoption first.

• Platforms
  • Gain support by two more PSP platforms for Payment Request API natively
• Merchants
  • Publish adoption trend data

  • Launch a Merchant Business Group
  • Create resources for merchants to easily create superior checkout experiences

Notes on participation:

• Have a UX component (e.g., UX experts and/or ordinary users providing feedback)

Notes on deliverables:

• Merchant requirements (e.g., on browser UX or functionality)
• Demos / videos. These should be shared within companies to help socialize adoption, and see whether the APIs align with business requirements or what would need to change.
