Hi,
At the moment, in order to be able to use Apple Pay for any standard subscription app in Shopify, your store needs to fulfill certain requirements posed by both Shopify and Apple Pay. These requirements are:
- Your store needs to use Shopify Payments.
- Your business needs to be located in the United States, Canada, Australia, or New Zealand.
- Your customers need to pay with a Mastercard or Visa card.
You can find these requirements on Shopify’s official documentation here: https://help.shopify.com/en/manual/payments/accelerated-checkouts/apple-pay
