Simple Payflow Transaction
All Payflow transactions include a common set of required parameters. Additional parameters
are required depending on the transaction type.You can also provide many optional
parameters, depending on the results you want returned. For example, you can set the
VERBOSITY parameter to return PayPal processor-specific details rather than normalized
information if you are looking for this kind of information. VERBOSITY is described in detail
in Appendix D, “VERBOSITY: Viewing Processor-Specific Transaction Results.”
Transaction Requests
Request Contents
A transaction request includes:
z Connection parameters
z User parameters
z Parameters specific to the type of the transaction, such as a sale or an authorization
Data Modes for Sending
You can send parameter data in the transaction request to the Payflow server in either of two
modes:
z Name-value pair
z XMLPay
The examples in this guide are presented in name-value pair format. Name-value pair syntax
guidelines are described in “PARMLIST Syntax Guidelines” on page 20.
XMLPay is an XML syntax for payment requests and associated responses in a payment-
processing network. Instead of using name-value pairs, you can send XML documents to the
Payflow server based on the XMLPay 2.0 schema. For details on XMLPay, see XMLPay
