Does Safari only supports Apple Pay, unlike the Chrome implementation and the actual W3 Payment Request API specifications? https://developers.google.com/web/fundamentals/payments/ https://developers.google.com/web/fundamentals/payments/ https://www.w3.org/TR/payment-request/ https://www.w3.org/TR/payment-request/

The very first line of the article states: “We’re pleased to announce that Safari 11.1 on macOS and Safari on iOS 11.3 now support the W3C Payment Request API for conducting Apple Pay transactions on the web.”

  Yes, I read that part: "W3C Payment Request API for conducting Apple Pay transactions" My question is: is this only for Apple Pay? Safari won't support any other payment method/service?

    I’m not sure I understand the question - what other payment service are you thinking of? With this change developers can use the same code to initiate a payment no matter which browser they are in, instead of having to write custom code for triggering Apple Pay, that’s the win here. This doesn’t change how Apple Pay for the web works. You can use Stripe or any other merchant processor to process your Apple Pay payments, iirc.

      The original specification and the Chrome implementation aren't restricted to a single payments app, such as Apple Pay: > The browser then presents the payments UI to the user, who selects a payment method and authorizes the transaction. A payment method can be as straightforward as a credit card that is already stored by the browser, or as esoteric as third-party application written specifically to deliver payments to the site. So if you have the PayPal app installed, you should be able to choose it as the payment method and so on. My question is if the Apple implementation on Safari restricts the payment methods only to Apple Pay, bocking any other payment services or apps.

        The ability for apps like PayPal to handle payments in the browser requires the Payment Handler API [1]. We aren't announcing support for Payment Handler here, just Payment Request. It's not like we're actively restricting or blocking these apps, we just haven't written the code to do this. [1] https://w3c.github.io/payment-handler/ https://w3c.github.io/payment-handler/

The Payment Request spec is agnostic to payment methods. It doesn’t require implementors to support any particular method(s). WebKit implements Payment Request, and Safari supports Apple Pay as a payment method. Other browsers that implement Payment Request might support other methods. Edit: spelling

      What about the reverse, will apple Pay work in Chrome? Assuming ofcourse you have set it up on a apple device first.

        Chrome does support other payment apps, not sure if Apple Pay blocks Chrome. Also, Chrome on iOS has to use the Safari rendering engine, since Apple blocks third party rendering engines, so not sure if that would actually work. Essentially, that's Apple making sure that if you have an iPhone, you can use any payment method, as long as it is Apple Pay.
