My team and I are building a custom/private app and we’ve hit a snag with checking out. In the Storefront API docs, there seems to be an indication that there are several options for completing a checkout with payment information. After looking at several forum posts, however, it seems that this is actually not possible with a custom storefront.
Does anyone have any definite information on what is possible to do through the API on a custom private app storefront for actually completing a checkout with payment? Can we use Shopify Card Vault?
Thanks!
