Gateway or Processor
Your choice of payment methods and vendor are set in the Cartweaver Setup
server behavior. Here you designate which method you will be using, Gateway (aprox. $50 monthly) or
Payment Processor (aprox. 3%), and the vendor you will be using. The vendors currently
available for Cartweaver are; Gateways – Authorize.Net (AIM) and Verisign Payflow
Pro; Payment Processors – PayPal and WorldPay Select Junior.
How Real-Time Gateways Work
Gateways process credit card transactions in-line. As an order is processed,
Cartweaver sends the credit card details to the gateway. While the gateway verifies
the credit card transaction, Cartweaver waits for a response. After the gateway
responds Cartweaver continues processing the rest of the order based on the result
of the credit card transaction. If a transaction fails for whatever reason (bad card
number, incorrect expiration date, etc.), then an error is displayed to the user and
they are given the opportunity to enter new credit card information. If the
transaction is successful, then the order is immediately written to the database.
How Non-Real-Time Payment Processors Work
Payment processors process the transaction in a completely separate space from
the application. The page code, including gateway code, is processed all at once.
The parameters are passed to the gateway either via FORM submittal or HTTP Post
and the order is written to the database without regard to what happens at the
payment processor.
