RESULT Values for Communications Errors
A value for RESULT 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.
NOTE: Details of the response message may vary slightly depending on your SDK integration.
