RESULT Values for Communications Errors
A RESULT value less than zero indicates that a communication error occurred. In this case, no
transaction is attempted.
A value of -1 or -2 usually indicates a configuration error caused by an incorrect URL or by
configuration issues with your firewall. A value of -1 or -2 can also be possible if the PayPal
servers are unavailable, or an incorrect server/socket pair has been specified. A value of -1 can
also result when there are internet connectivity errors. Contact customer support regarding any
other errors.
For information on firewall configuration, see Chapter , “Downloading, Installing, and
Activating.”
N OTE: To eliminate RESULT -31 and -108 errors described below, upgrade to a version 4
SDK or post directly to the Payflow servers via HTTPS. For details on determining the
version of your SDK, see “Payflow SDK Version” on page 15.
Details of the response message may vary slightly from that shown in the table, depending on
your SDK integration.
