A system receives an object selection, and outputs the object. The system receives a first service selection, outputs the first service's object, receives a second service selection, and outputs the second service's object. The system receives selections of the object's first field and the first service object's field, and stores first metadata that maps between the object's first field and the first service object's field. The system receives selections of the object's second field and the second service object's field, and stores second metadata that maps between the object's second field and the second service object's field. The system updates an object instance by using the first metadata to send first request data to the first service and receive first response data from the first service, and by using the second metadata to send second request data to the second service and receive second response data from the second service.
