Sending informaton to a sage pay payment gateway

Question

I have product designer software in my website that currently allows customers to design a product and get a live price. The software has the ability to send a message to the parent of an iframe where the information can be processed as I like. I want this information to be sent to my sagepay, worldpay or stripe payment gateway to give the customers the ability of purchasing the product.

Does anyone have any idea how to achieve this or even where to start!

Thanks in advance Dan

Answer 1

Most payment gateways allow somehow to send the details of the purchased products details via API when processing the payment.

For SagePay (if you mean the one which currently is labeled as Opayo by Elavon) you may use the detailed basket via XML or CSV. Or you may simply use the common Description field.

For Worldpay it's the instruction.narrative.line1 field from the authorization request.

And for Stripe it should be either metadata or payment_intent_data objects.
