Abstract: A method is disclosed. The method comprises receiving, by a virtual terminal, virtual terminal configuration data from a virtual terminal configuration data source via a virtual terminal configurations API. The method also includes transmitting, by virtual terminal, to a device reader, a value, and receiving, by the virtual terminal, access data from a user device via the device reader. The method further includes transmitting, by the virtual terminal, a transaction request comprising at least the value and the access data to a transaction platform via a transaction API, and receiving, by the virtual terminal, a transaction response from the transaction platform via the transaction API.

Abstract: A method is disclosed. A server computer receives, from a client computer, of a plurality of client computers, a transaction state object indicating that a transaction has been initiated. The server computer transmits, to a first subset of the client computers, a notification that the transaction has been initiated. The server computer receives, from a second client computer, a first modification to the transaction state object indicating that a first step has been executed. The server computer transmits, to a second subset of the client computers, a notification that the first step in the transaction has been executed. The server computer receives, from a third client computer, a second modification to the transaction state object indicating that a second step in the transaction has been executed. The server computer transmits, to a third subset of the client computers, a notification that the second step has been executed.

Abstract: Embodiments of the invention are directed to systems and methods for common request processing by a request formatting platform. The request formatting platform generates formatted requests for request processors according to specifications of a common request processing application programming interface (API). The same common request processing API is used by the request formatting platform to communicate with all of the request processors according to one particular format.

Abstract: Embodiments of the invention are directed to techniques for redirecting data streams from a production environment to validate non-production software code. In some embodiments, a front-end computer executing a first version of software can receive a request message from a requesting computer, generate a request payload using the request message, transmit the request payload to a processor computer, receive a response payload from the processor computer, generate a reply message using the response payload, and provide, to a validation computer that is executing a second version of the software, the request message, the request payload, and the response payload. The validation computer can generate a modified request payload using the request message and a modified reply message using the response payload. To detect potential errors in the second version, the modified request payload is compared with the request payload and the modified reply message is compare with the reply message.
