Integrate Stripe with Shopify for Checkout and Completing the Checkout

Retired Boards Appdev Custom Storefronts

On further research, all I would need is to support the use case of

  1. taking in credit card info only once from the user, create a stripe customer object

  2. Get the token for completing a checkout using customer id (stripe platform’s one) and complete the checkout using the token
    OR

2’. Somehow pass the customer id info to Shopify checkout API and complete the checkout.

Would be great if someone can advise whether 2 or 2’ is possible using shopify storefront API?
