A user interface service composer determines, based on a user interface request from a user interface consumer, one of a plurality of user interface service providers to be invoked; and consults a particular entry (corresponding to the service provider to be invoked) in a user interface data catalog having a plurality of entries for the plurality of user interface service providers. A request message, for rendering a user interface requested in the user interface request received from the user interface consumer, is routed from the user interface service composer to the given one of the plurality of user interface service providers that is to be invoked. The request message includes configuration parameters and interaction-related data, and is formatted in accordance with the particular entry in the user interface data catalog. The user interface service composer receives, from the given one of the plurality of user interface service providers that is to be invoked, the user interface requested in the user interface request received from the user interface consumer; and forwards, to the user interface consumer, the user interface requested in the user interface request received from the user interface consumer.
