A method of optimizing communication and processing functions between disparate applications includes sending, from a first application to a disparate second application, a request message. The request message, which has a reduced data size for optimizing communication, is formatted in a first request-format to provide unique data elements relevant to processing the request message. The received request message is reformatted into a second request format, and is then forwarded to a third application. The third application creates a response message that is in a first response format, and sends the response message to the second application. Each received response message is queued, by a messaging application, into a response message collection corresponding to a message type, before sending the response group to the first application.
