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 Payment Request API is a Candidate Recommendation and has already been implemented in other major web browsers. The API is extensible to any payment method without requiring the browser to be Payment Card Industry (PCI) compliant.

Status Summary

Development Update - Milestones 4 Delivery - Tuesday November 20

Below is a weekly engineering development update.

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.
