Our team is building a Sales Channel and got stuck on the Payment step. We are planning to use Shopify Payment API to finish a checkout process on our side. Thus, we have created a Stripe (Connect) Account in order to tokenise credit cards without sending them to Shopify Card Vault and being PCI-compliant. We have also been granted an access to Payment API from Shopify and got a confirmation from Stripe.
I am just wondering that, in the docs it's said that Stripe ID has to be one that's coming from a created checkout in shopify_payment_account_id field which actually makes sense. And this is why probably, Shopify can not match the tokens. However, I was told from Shopify Support that we have to use the Stripe ID of our platform. I am a bit confused about it and would appreciate your help!
