Specification

Design docs

Summary

This is a Javascript API to provide an easier way to check if the Secure Payment Confirmation[1] feature is available. Currently, the only way to determine SPC’s availability is to create a PaymentRequest with the required parameters[2], which is clunky and difficult in the case where a developer wants to check for SPC before starting to process a payment.

WebKit: N/A (https://github.com/WebKit/standards-positions/issues/30)

Web developers: Positive (https://github.com/w3c/secure-payment-confirmation/issues/81) We've received feedback from web developers that an easier mechanism to check for SPC availability would be useful.

Other signals:

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

None



Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Yes

Is this feature fully tested by web-platform-tests?

LGTM1

Thanks for adding feature detection capabilities!!

I see some discussion on the PR about it being approved but not yet landed, due to desire to move a previous version to PR.
That seems fine, but at the same time, I join +Rick Byers' request to make sure the situation doesn't last too long. Also, you may want to consider moving to a Living Standard model, that typically can avoid those kinds of issues..

LGTM2.

I think it would be valuable to extend the spec PR with more description of the considerations around when the feature is available (see discussion at https://github.com/w3c/secure-payment-confirmation/issues/81#issuecomment-1527105768), but I don't think that will meaningfully change the shape of the API or its meaning in Chromium's implementation.
