Please help.
How can a 3rd party, some how send an email to a customer, that one their phone, they use to register their phone to have a new Apple Pay account?
And preferably, such that, when used with any Merchant, some unique identification related to the 3 party is put into the transaction with the merchant, so the merchant will know the 3rd party is related to any transaction the customer make?
To clarify one point, the customer may already have their own Apple Pay account, and as such, this registration process would add onto their Apple Pay accounts for which we'd need to ensure the customer knew which Apple Pay account they were using when making a purchase.
