Hello! My store site is fully headless, with the exception of our current checkout screen which uses the standard Shopify Checkout template. I'm looking to make our checkout screen headless as well, built using React, and am having trouble understanding what APIs could be used for this. From my understanding, the Storefront API does not have any APIs for processing a checkout with a payment, but the Admin API appears to have support for this here.
Is the Admin API approach the way to go here, and if so, how might I use it with Shopify Payments after a customer has entered their payment info?
