Contents of a Transaction Request

Table 3-1 describes the connection parameters that you need to pass when submitting a

transaction request to the Payments gateway. Pass them in the format and syntax required by

the SDK and programming language that you are using. See your integration documentation

for details.

PARMLIST Syntax Guidelines

Follow these guidelines when creating the PARMLIST:

TABLE 3.1 Connection parameters

Argument Required Description

HOSTADDRESS Yes PayPal’s host name.

For live transactions, use payflowpro.verisign.com

For testing purposes, use pilot-payflowpro.verisign.com

HOSTPORT Yes Use port 443

PARMLIST Yes The PARMLIST is the list of parameters that specify the payment

information for the transaction. The quotation marks “ ” at the beginning

and end are required. In the example, the ParmList is:

“TRXTYPE=S&TENDER=C&PARTNER=PayPal&VENDOR=SuperMercha

nt&USER=SuperMerchant&PWD=x1y2z3&ACCT=555555555555444

4&EXPDATE=0308&AMT=123.00”

The content of the PARMLIST varies by the type of transaction being

processed. For example, a Void transaction requires a different set of

parameters than does a Sale transaction.

“Parameters Used in Credit Card Transactions” on page 19 defines the

parameters used to create credit card transactions. “Values Required by

All Transaction Types” on page 23 lists the parameters required by each

transaction type.

TIMEOUT Yes Time-out period for the transaction. The minimum recommended time-

out value is 30 seconds. The PayPal client begins tracking from the time

that it sends the transaction request to the PayPal server.

PROXYADDRESS No Proxy server address. Use the PROXY parameters for servers behind a

firewall. Your network administrator can provide the values.

PROXYPORT No Proxy server port

PROXYLOGON No Proxy server logon ID

PROXYPASSWORD No Proxy server logon password
