Abstract

In one example, a server system in an electronic trading system facilitates an exchange of messages with a remote client application. An Application Program Interface (API) receives a first request message and a second request message, wherein the first request message including a first data payload defined by a common data component and including a first extended payload data, the first extended payload defined by a first schema definition. The second request message includes a second data payload defined by the common data component and a second extended payload data, wherein the second extended payload is defined by a second schema definition different than the first schema definition. In response to receiving the first request message, the API transmits a first response message, and in response to receiving the second request message, the API transmits a second response message different than the first response message.

Claims

1. A server system in an electronic trading system to facilitate an exchange of messages with a remote client application, the server system including:

at least one application program interface server comprising a memory, at least one processor, and hosting an Application Program Interface (API);

the API receiving a first request message and the API receiving a second request message;

the first request message including a first data payload defined by a common data component and the first request message including a first extended payload data, the first extended payload defined by a first schema definition;

the second request message including a second data payload defined by the common data component and the second request message including a second extended payload data, the second extended payload defined by a second schema definition, the second schema definition different than the first schema definition;

in response to receiving the first request message, the API transmitting a first response message; and

in response to receiving the second request message, the API transmitting a second response message, the second response message different than the first response message.

2. The system of claim 1, wherein the API is a marketplace web service.

3. The system of claim 2, wherein the first schema definition is defined by a first XML Schema Definition (XSD) file, and the second schema definition is defined by a second XSD file.

4. The system of claim 3, wherein the first XSD file comprises a first element representing a first entity and the second XSD file comprises a second element representing a second entity, the first element different than the second element and the first entity different than the second entity.

5. The system of claim 3, wherein the first XSD file defines any one of an item listing, a payment, an inventory, an image, an order, a bid, or a transaction.

6. The system of claim 5, wherein a first version of the system is customized for a first geographic location and a second version of the system is customized for a second geographic location.

7. The system of claim 1, the first response message including an additional code not defined by the first schema definition.

8. The system of claim 1, wherein the first response message includes an error.

9. The system of claim 1, wherein the common data component includes a timestamp.

10. The system of claim 1, wherein the common data component includes a correlation identifier.

11. A method, at a server system in an electronic trading system, for facilitating an exchange of messages with a remote client application, the method including, at least:

hosting an Application Program Interface (API) at an application program interface server;

receiving, by the API, a first request message and a second request message, the first request message including a first data payload defined by a common data component and a first extended payload data, the first extended payload defined by a first schema definition, and the second request message including a second data payload defined by the common data component and a second extended payload data, the second extended payload defined by a second schema definition, the second schema definition different than the first schema definition;

transmitting, by the API, a first response message in response to receiving the first request message; and

transmitting, by the API, a second response message in response to receiving the second request message, the second response message different than the first response message.

12. The method of claim 11, wherein the API is a marketplace web service.

13. The method of claim 12, wherein the first schema definition is defined by a first XML Schema Definition (XSD) file, and the second schema definition is defined by a second XSD file.

14. The method of claim 13, wherein the first XSD file comprises a first element representing a first entity and the second XSD file representing a second entity, the first element different than the second element and the first entity different than the second entity.

15. The method of claim 13, wherein the first XSD file defines any one of an item listing, a payment, an inventory, an image, an order, a bid, or a transaction.

16. The method of claim 15, wherein a first version of the system is customized for a first geographic location and a second version of the system is customized for a second geographic location.

17. The method of claim 11, the first response message including an additional code not defined by the first schema definition.

18. The method of claim 11, wherein the first response message includes an error.

19. A non-transitory machine-readable medium comprising instructions which, when read by a machine, cause the machine to perform operations comprising, at least:

hosting an Application Program Interface (API) at an application program interface server;

configuring the API to receive a first request message and a second request message, the first request message including a first data payload defined by a common data component and a first extended payload data, the first extended payload defined by a first schema definition, and the second request message including a second data payload defined by the common data component and a second extended payload data, the second extended payload defined by a second schema definition, the second schema definition different than the first schema definition;

transmitting, by the API, a first response message in response to receiving the first request message; and

transmitting, by the API, a second response message in response to receiving the second request message, the second response message different than the first response message.

20. The medium of claim 19, wherein the first schema definition is defined by a first XML Schema Definition (XSD) file, and the second schema definition is defined by a second XSD file.
