Error Codes



Overview  
In cases when a system error occurs, the gateway returns an exception.

As a transaction, for which an exception is received, does not go through the gateway's validation, it's not submitted to a processor either. For this reason, such transactions can be stored neither within the database nor in the list of transactions.

Every exception consists of the following elements:

1. failureCode is a unique identifier for exceptions, composed of two elements:

- a letter indicating a category of a code;
- a unique number (digit) indicating an error code.

Below, you can find a list of letters that determine an error categories:















Error categories Description
E (Connectivity Error) occurs, when there is no connection with a server due to network connectivity issues.

For example, the connection might time out due to a failure in the internet connection.
L (Login/Security Error) occurs when a login attempt is unsuccessful or a user misses one or more privileges to be able to use API;
F (Formatting Error) occurs when data provided by a submitter does not adhere to the formatting requirements.

For example, a submitted value for phone field contains letters or a submitted value for amount field is negative;
V (Data Verification Error) occurs when data provided by a submitter is well-formatted, but one or more values are not valid from the business context.

For example, referenced merchant account does not exist or a specified transaction industry type has not been found within a list of the allowed values;
O (Configuration Error) occurs when data provided by a submitter is well-formatted and valid, but specific settings required for a transaction to be processed are not configured correctly.

For example, there are no pricing templates configured within specified portfolio while a merchant that is being created cannot be onboarded without these settings;
U (Unsupported Action Error) occurs when data has been validated successfully and all required settings are configured, but specified operation/feature is not supported either by the gateway or a processor.

For example, operation is not supported by an underlying processor or cashback is not supported for sale-info or credit-info operations;
S (System Error) an internal system error occurred. Gateway support should be reached out;
Q (Security Error) occurs when there is a possibility of a security breach or missed encoding;
W (Warning) no error occurs. However, transaction processing did not go smoothly, and a warning has been received. To review the warning related to the transaction, see the system error log or a system audit notification is received by the gateway.


2. failureMessage consists of the details of an exception that specify the reason why the transaction cannot be processed.

Below, you can find the structure of the failure message:




Message Description
User message a message describing what caused the error, for example, zipCode is not well-formatted.
Developer message a message containing a list of dynamic parameters included in the user message. Using these parameters, you can override user messages with your own custom error messages. See Processing Management Guide for more information.
Hint a number, which refers to the additional information about an error, for example, Hint:1. If a hint is returned as a part of the failure message, you should refer to the description of the corresponding error in the section below.


If needed, the structure of error messages can be modified at the service user level via the Response Msg Display Policy setting by removing or adding any of the options described above.

These exceptions are currently used within the gateway. In the previous versions of the application, as well as in the older logic, deprecated exceptions can still be present. For more information see Deprecated Codes.

Configuration Error Codes
