An embodiment of the present executes a sequence of a plurality of application programming interfaces. Request objects are generated for the application programming interfaces of the sequence. Each request object is generated in accordance with a common object model. Execution of each application programming interface is enabled in an order of the sequence to process a corresponding request object and generate a corresponding response object containing results. Each response object is generated in accordance with the common object model and includes information from the corresponding request object aggregated with the results. Further, each request object for a succeeding application programming interface in the sequence includes the aggregated information from a response object of a prior executed application programming interface in the sequence.
