Guidelines when using Business Object Document-style Web services for integration
Follow these guidelines when using Business Object Document-style (BOD-style) Web services for integration.
- Only a WebSphere Commerce service module should use its external facade client for outbound requests. For example, only the Order service module should use the order external facade client. If a client application or another service module requires order information, the default order facade client should be used to make a service request to the WebSphere Commerce order service. The WebSphere Commerce order service would then make an outbound request if necessary.
- Use InsertMore commands:
- Use InsertMore commands to retrieve data from an external system and include the data in a response.
- Try to batch the external system request into one request and merge the result set back together. See Include change control information in the response of a Get service for a sample implementation.
