API server and method of usage thereof

Abstract:

A system, method and software using a common language-independent interface to interact with multiple hosts are generally described. POS terminals and ICRs interact with a PMI acting as a payments API server. The PMI contains rest-based APIs that are able to respond to HTTP requests for transactional and testing purposes. The PMI communicates with EPS in an EPC interact with an epsilon interface to process transactions and interact with payment hosts, a sigma interface to process loyalty transactions and interact with loyalty hosts and a POSCache interface to interact with pinpads.
