I have a webshop, and I would accept Bitcoin payment. I have a Bitcoin address where I accept payment.
Is it a procedure to pass an id or ask an id to / from the transaction? When I query the received transactions I nee to know to which program it was bought. Who is the user, what is its email.
At other payment providers that create a
paymentId and return it to the shop, and that
paymentId will be also in the payment I can fetch later. How could it work with Bitcoin?
