Method, system, and computer program product for configuring a gateway

A system for configuring a payment gateway of a transaction service provider system, comprising:

• a payment gateway of a transaction service provider system that receives transaction authorization requests from merchant systems and communicates with issuer systems, the payment gateway configured to:
• monitor current validation rules version data stored on at least one first server, the current validation rules version data associated with a current version of a validation rules configuration file for the payment gateway, the at least one first server remote from the payment gateway, wherein monitoring comprises performing, by a first agent on the payment gateway, a watch command to monitor a view of at least a portion of the current validation rules version data from a second agent on the at least one first server;
• determine that the current validation rules version data stored on the at least one first server has been modified;
• in response to determining that the current validation rules version data has been modified, invoke a configuration service, wherein the configuration service retrieves the current version of the validation rules configuration file from at least one repository based on the current validation rules version data, the at least one repository comprising at least one second server remote from the payment gateway and the at least one first server;
• store a copy of the current version of the validation rules configuration file retrieved by the configuration service;
• receive a first transaction authorization request from a merchant system;
• apply the copy of the current version of the validation rules configuration file to the first transaction authorization request;
• and
• validate the first transaction authorization request based on applying the copy of the current version of the validation rules configuration file to the first transaction authorization request.

A computer program product for configuring a payment gateway of a transaction service provider system, the computer program product comprising at least one non-transitory computer-readable medium including one or more instructions that, when executed by at least one processor, cause the at least one processor to:

• monitor current validation rules version data stored on at least one first server, the current validation rules version data associated with a current version of a validation rules configuration file for a payment gateway of a transaction service provider system that receives transaction authorization requests from merchant systems and communicates with issuer systems, the at least one first server remote from the payment gateway, wherein monitoring comprises performing, by a first agent on the payment gateway, a watch command to monitor a view of at least a portion of the current validation rules version data from a second agent on the at least one first server;
• determine that the current validation rules version data stored on the at least one first server has been modified;
• in response to determining that the current validation rules version data has been modified, invoke a configuration service, wherein the configuration service retrieves the current version of the validation rules configuration file from at least one repository based on the current validation rules version data, the at least one repository comprising at least one second server remote from the payment gateway and the at least one first server;
• store a copy of the current version of the validation rules configuration file retrieved by the configuration service;
• receive a first transaction authorization request from a merchant system;
• apply the copy of the current version of the validation rules configuration file to the first transaction authorization request;
• and
• validate the first transaction authorization request based on applying the copy of the current version of the validation rules configuration file to the first transaction authorization request.
