Support Details

Developers are cautioned that code that makes programmatic calls to the SharePoint environment by using Web services can work as expected when run in a development environment with a small number of users, but can be a significant burden on performance when used in a production environment with a large user base. Similarly, frequent database updates to such code can cause a significant burden in a production environment. For example, using Web services to bulk load or synchronize a list with a database is risky, depending on the amount of data and the period of synchronization. A more acceptable use of code that accesses a Web service is for a Web Part to access a built-in service to query a set of items in a list.

Note   Web service access is supported only for documented Web services.
