What is the best way to integrate by payment gateway? by Joseph Anderson
How do they work?
They act as a middle man. They usually hold onto sales for two days, then deposit funds into your bank account.
What fields are available to match?
The minimum requirement is billing address, credit card details, billing frequency, and amount. In some cases, they send the product SKU, item title, item quantity, price, taxes, and shipping. This usually happens with custom carts or ordering forms. If no SKUs are sent, we can map fields like order description. We could say if the amount is $40, then the SKU is ABC. They sometimes return merchant fees. The processor returns a reference number, which is used to match sales and payments. The website order number is usually sent.
Should I sync with my website, payment processor, or both?
The website sends the order to the processor. They send back a success or failure message. The processor has a copy of the order. No need to sync both at the same time, unless orders are mutually exclusive.
Do you have a slide deck and a demo?
