A machine-readable storage device comprising instructions which, when executed by a machine, cause the machine to perform operations of facilitating an exchange of messages in a trading system between a remote client application and a server system, the server system being capable of supporting a plurality of application program interfaces, the operations comprising:

• receiving a plurality of request messages compiled by the remote client application, each of the plurality of request messages comprising at least one data component, and a request component that includes a reusable identified schema definition specific to one of the plurality of application program interfaces, to support the functionality of the requested application program interface;
• extracting the at least one data component and the request component from the request message;
• and
• performing the activity requested by the request message.
