The transaction result displays the overall status of the transaction. The result associated with each transaction appears on all PayPal Manager detail reports. If you use Post or Silent Post, then the RESPMSG parameter returns the description of the RESULT code.
A value of 0 (zero) indicates that no errors occurred and the transaction was approved.
A value greater than zero indicates a decline or an error. For result codes and their associated RESPMSG descriptions, refer to RESULT Values for Transaction Declines or Errors.
A value less than zero indicates that a communication error occurred. In this case, no transaction is attempted. For information regarding communication error RESULT values, refer to RESULT Values for Communication Errors.
