System, method and apparatus for computer communication

Abstract

Embodiments of the present invention provide a system, comprising a first computer associated with a first service provider, a second computer associated with a second service provider, and a third computer executing a user application, wherein the third computer is arranged to obtain first registry data identifying a first endpoint associated with the first computer and second registry data identifying a second endpoint associated with the second computer; obtain, from the first endpoint, a first service resource indicative of a mapping between one or more API endpoints associated with the first computer and one or more resource types associated with the user application of the third computer, and, from the second endpoint, a second service resource indicative of a mapping between one or more API endpoints associated with the second computer and one or more resource types associated with the user application of the third computer; initiate communication with the first computer via a first API instance according to a predetermined API protocol to exchange data with the first computer in dependence on the first service resource, wherein the third computer provides a context value indicative of an identity of the user application to the first computer; initiate communication with the second computer via a second API instance according to the predetermined API protocol to exchange data with the second computer in dependence on the second service resource, wherein the third computer provides the context value indicative of the identity of the user application to the second computer.
