Thanks for the response. To narrow down the scope of my question a bit: Do you have any plans to open up API endpoints that would afford us the privilege of choosing a gateway on our own?
I'm asking because our checkout is completely devoid of Checkout or Stripe.js, i.e. the "building the whole payment form" route you mention on the checkout page: https://stripe.com/docs/tutorials/forms.
No, just whether or not you'd implement Alipay into your API in a manner that would allow for us to handle the frontend UI ourselves (letting our users chose between Alipay or credit card).
We felt that Checkout was the best integration point because it let us do some nice dynamic authentication logic instead of Alipay's usual redirect-based flow. Given that subtleties involved, Alipay's constraints, and the fact that it'll no doubt need to evolve in the future (as compared to the static standardization of credit cards), I think it'd be pretty tough to expose it via a straight API.
