Firefox/Features/Web Payments

Introduction

The Payment Request API makes online purchases easier without having to fill in all of the personal and payment information over and over again. Together with the form autofill feature, it saves user's time and effort when making online purchases by storing their personal and payment information in Firefox to be used when a merchant requests payment. The Payment Request UI provides consistency across merchant sites.

The overall objective is to increase user engagement, satisfaction, and retention for frequent online shoppers. We believe this can be achieved by enabling users to complete forms and “check out” in e-commerce flows as quickly and securely as possible.

The W3C PaymentRequest API is currently in draft stage and has momentum. The API is extensible to any payment source without requiring the browser to be Payment Card Industry (PCI) compliant.

Tentative plan for 2018’H2

• Frontend: Basic card UI implementation. Known dependencies include:
  • 1. (Completed) UX design reiteration V1.7: Jacqueline. (see also: Web Payment - Basic Card (MVP) design doc.
  • 2. Front-end Resources: 3 Engineers
  • 3. (Confirmed) Reviewer’s availability: MattN
  • 4. (Confirmed) No other feature dependency (e.g., Any Lockbox dependency?)
  • 5. (Confirmed) Compliance for Basic card UI (or that’s only for Payment Handler?)? e.g., PA-DSS by PA-QSA

• Platform: Ensure Payment Request APIs “ready to enable” (disable until FE ready) in Q3
  • API Compat. test coverage / compliance
  • Basic card spec. implementation
  • (Q3 and more) Marcos keeps working on W3C spec of both the Payment Handler/Request
  • (Q3 and more) Bridging UI and the Request API (subject to FE’s actual progress), including 2 parts:
    • Connecting UI: ongoing and will complete in Q3;
    • IntegrationL requires FE completion to start (e.g., fix bugs during UI integration and verification on merchant website like WooCommerce).

Achievement in 2017'H1

• • (Done) Payment Request API development.
  • (Done) User research of Payment Request (Basic Card) UX.
  • (Done) Payment Request Handler API Proposal. It's been merged into the renamed Payment "Handler" API (was the Payment "App" API) spec.

Milestones

from the breakdown document

M1

End-to-end test with valid user data and merchant update/change events, no Fx validation, generic merchant error string, only already stored cards/addresses

M2

add/edit screens, only basic validation (e.g. non-empty) and address-field-specific merchant-provided errors

M3

FTU, data validation & error recovery, "update" badge, telemetry, ready to enable on fx63 Nightly-only / Partner / End-to-end User Testing (not riding the trains)

M4

Tab modal widget (maybe do in parallel), UI feature complete, ready for release users, Visual Polish, cc logos

MVP

Ride the trains

DOM

See Firefox/Features/Web_Payments/DOM for more info.

• Bugzilla Component: DOM: Web Payments
• Intent to Implement
• Platform implementation Architecture
• Old
  • DOM Code WIP Repository

Quality Assurance

• TBD. The pure API development in H1 doesn't require QA involvement (UI level verification). We will have unit/autotest instead.
