WooPayments’ Express Checkout implementation is based on Stripe's PRB element. The PRB element is a legacy element based on W3C standards. Being a web standards body, W3C updates are far and few between and Stripe has little control.
Stripe recommended in 2023 that we move to the Express Checkout Element, which expands functionality and is based off of direct integrations with Apple and Google. Combined with the upcoming Stripe express checkout domain registration compliance date, which changes how domains are registered with the express checkout providers, the timing is right to migrate to this new element.
The main problem with the current implementation is a lack of browser compatibility, particularly on mobile, and Google Pay is not appearing when 3rd party cookies are blocked. We're observing very low usage of Google Pay relative to Apple Pay despite Chrome having a dominant market share.
Google Pay and Apple Pay buttons are visible even if 3rd party cookies are blocked
Completed for Blocks and Shortcode checkouts
The FSE Blocks experience for express checkout is functional post migration
Phase 2
Link is supported as an express checkout option in addition to Link support in the email field. Link in the Pay With section will continue to not be supported at this time.
Link and WooPay continue to be mutually exclusive options. Open question: Can Link still be an Express Checkout button option is WooPay has control over the email field?
Existing data telemetry carries over
Express Checkout custom field detection and notification carries over
Phase 3 - Open question: Should we wait for the Merchant Settings refresh and move this phase to that effort?
Corner radius, i.e. pill shaped buttons, is supported. Requires design.
Express Checkouts as options in the payment methods list. Help provide a level of compatibility for checkouts with custom fields.
Designs
Required for Phase 3 and are being developed as part of the Merchant Settings refresh effort.
