/*
 * RESULT values (and RESPMSG text)
 *
0 Approved
1 User authentication failed. Error is caused by one or more of the following:
Login information is incorrect. Verify that USER, VENDOR, PARTNER, and
PASSWORD have been entered correctly. See Table 3.2 on page 26 for additional
information and field descriptions.
Invalid Processor information entered. Contact merchant bank to verify.
"Allowed IP Address" security feature implemented. The transaction is coming
from an unknown IP address. See VeriSign Manager online help for details on how
to use Manager to update the allowed IP addresses.
You are using a test (not active) account to submit a transaction to the live VeriSign
servers. Change the URL from pilot-payflowpro.paypal.com to payflowpro.paypal.com.
2 Invalid tender type. Your merchant bank account does not support the following
credit card type that was submitted.
3 Invalid transaction type. Transaction type is not appropriate for this transaction. For
example, you cannot credit an authorization-only transaction.
4 Invalid amount format. Use the format: #####.##  Do not include currency
symbols or commas.
5 Invalid merchant information. Processor does not recognize your merchant account
information. Contact your bank account acquirer to resolve this problem.
6 Invalid or unsupported currency code
7 Field format error. Invalid information entered. See RESPMSG.
8 Not a transaction server
9 Too many parameters or invalid stream
10 Too many line items
11 Client time-out waiting for response
12 Declined. Check the credit card number, expiration date, and transaction information to
make sure they were entered correctly. If this does not resolve the problem, have the
customer call their card issuing bank to resolve.
13 Referral. Transaction cannot be approved electronically but can be approved with a
verbal authorization. Contact your merchant bank to obtain an authorization and submit
a manual Voice Authorization transaction.
14 Invalid Client Certification ID. Check the HTTP header. If the tag, X-VPS-VIT-
CLIENT-CERTIFICATION-ID, is missing, RESULT code 14 is returned.
19 Original transaction ID not found. The transaction ID you entered for this
transaction is not valid. See RESPMSG.
20 Cannot find the customer reference number
22 Invalid ABA number

23 Invalid account number. Check credit card number and re-submit.
24 Invalid expiration date. Check and re-submit.
25 Invalid Host Mapping. You are trying to process a tender type such as Discover Card,
but you are not set up with your merchant bank to accept this card type.
26 Invalid vendor account
27 Insufficient partner permissions
28 Insufficient user permissions
29 Invalid XML document. This could be caused by an unrecognized XML tag or a bad
XML format that cannot be parsed by the system.
30 Duplicate transaction
31 Error in adding the recurring profile
32 Error in modifying the recurring profile
33 Error in canceling the recurring profile
34 Error in forcing the recurring profile
35 Error in reactivating the recurring profile
36 OLTP Transaction failed
37 Invalid recurring profile ID
50 Insufficient funds available in account
99 General error. See RESPMSG.
100 Transaction type not supported by host
101 Time-out value too small
102 Processor not available
103 Error reading response from host
104 Timeout waiting for processor response. Try your transaction again.
105 Credit error. Make sure you have not already credited this transaction, or that this
transaction ID is for a creditable transaction. (For example, you cannot credit an
authorization.)
106 Host not available
107 Duplicate suppression time-out

108 Void error. See RESPMSG. Make sure the transaction ID entered has not already been
voided. If not, then look at the Transaction Detail screen for this transaction to see if it
has settled. (The Batch field is set to a number greater than zero if the transaction has
been settled). If the transaction has already settled, your only recourse is a reversal
(credit a payment or submit a payment for a credit).
109 Time-out waiting for host response
111 Capture error. Either an attempt to capture a transaction that is not an authorization
transaction type, or an attempt to capture an authorization transaction that has already
been captured.
112 Failed AVS check. Address and ZIP code do not match. An authorization may still
exist on the cardholder account.
113 Merchant sale total will exceed the sales cap with current transaction. ACH
transactions only.
114 Card Security Code (CSC) Mismatch. An authorization may still exist on the
cardholder account.
115 System busy, try again later
116 VPS Internal error. Failed to lock terminal number
117 Failed merchant rule check. One or more of the following three failures occurred:
An attempt was made to submit a transaction that failed to meet the security settings
specified on the Payflow Pro Java SDK Security Settings page. If the transaction
exceeded the Maximum Amount security setting, then no values are returned for AVS
or CSC.
AVS validation failed. The AVS return value should appear in the RESPMSG.
CSC validation failed. The CSC return value should appear in the RESPMSG.
118 Invalid keywords found in string fields
122 Merchant sale total will exceed the credit cap with current transaction. ACH
transactions only.
125 Fraud Protection Services Filter _ Declined by filters

126 Fraud Protection Services Filter _ Flagged for review by filters
Important Note: Result code 126 indicates that a transaction triggered a fraud filter.
This is not an error, but a notice that the transaction is in a review status. The
transaction has been authorized but requires you to review and to manually accept the
transaction before it will be allowed to settle.
Result code 126 is intended to give you an idea of the kind of transaction that is
considered suspicious to enable you to evaluate whether you can benefit from using the
Fraud Protection Services.
To eliminate result 126, turn the filters off.
For more information, see the User Guide for Payflow Pro With Fraud Protection
Services or User Guide for Payflow Link Guide With Fraud Protection Services.
