System, method, and computer program product for dynamic application selection

A system for dynamic application selection for payment transactions, comprising at least one processor of a point-of-sale (POS) device, wherein the at least one processor of the POS device is programmed and/or configured to:

• determine identification data of an issuer institution associated with a portable financial device based at least partially on transaction data associated with at least one transaction at a merchant with the portable financial device;
• determine at least one electronic service application of a plurality of electronic service applications based at least partially on the identification data of the issuer institution, wherein a plurality of electronic service application data associated with the plurality of electronic service applications is stored in association with a plurality of issuing institutions at a merchant system of the merchant, and wherein the plurality of electronic service application data comprises Application Programming Interface (API) information associated with the plurality of electronic service applications;
• initiate at least one API call to at least one external computing system associated with the at least one electronic service application to access the at least one electronic service application at the at least one external computing system;
• provide, via a display of the POS device, a graphical user interface including a prompt to accept the at least one electronic service application for processing the at least one transaction by accessing, with the at least one processor of the POS device, the at least one electronic service application at the at least one external computing system;
• receive, via the display of the POS device, acceptance data that indicates acceptance of the at least one electronic service application for processing the at least one transaction;
• modify the at least one transaction based at least partially on the electronic service application data associated with the at least one electronic service application;
• communicate to an issuer system associated with the issuer institution, an authorization request message associated with the at least one modified transaction;
• and
• receive an authorization response message after communicating the authorization request message.

A computer program product for dynamic application selection for payment transactions, the computer program product comprising at least one non-transitory computer-readable medium including program instructions that, when executed by at least one processor of a point-of-sale (POS) device cause the at least one processor of the POS device to:

• determine identification data of an issuer institution associated with a portable financial device based at least partially on transaction data associated with at least one transaction at a merchant with the portable financial device;
• determine at least one electronic service application of a plurality of electronic service applications based at least partially on the identification data of the issuer institution, wherein a plurality of electronic service application data associated with the plurality of electronic service applications is stored in association with a plurality of issuing institutions at a merchant system of the merchant, and wherein the plurality of electronic service application data comprises Application Programming Interface (API) information associated with the plurality of electronic service applications;
• initiate at least one API call to at least one external computing system associated with the at least one electronic service application to access the at least one electronic service application at the at least one external computing system;
• provide, via a display of the POS device, a graphical user interface including a prompt to accept the at least one electronic service application for processing the at least one transaction by accessing, with the at least one processor of the POS device, the at least one electronic service application at the at least one external computing system;
• receive, via the display of the POS device, acceptance data that indicates acceptance of the at least one electronic service application for processing the at least one transaction;
• modify the at least one transaction based at least partially on the electronic service application data associated with the at least one electronic service application;
• communicate to an issuer system associated with the issuer institution, an authorization request message associated with the at least one modified transaction;
• and
