Welcome to the Project Data Service (PDS) Usage and Methods Reference for Microsoft® Project Server.

This reference explains how to use the PDS Application Programming Interface (API) to allow client applications to access Microsoft Project Server portfolio data. Client applications can programmatically log on to Microsoft Project Server and use Simple Object Access Protocol (SOAP) to call PDS API methods. The PDS implements a SOAP listener, which receives method calls in Extensible Markup Language (XML) format and returns an XML response.

This documentation includes example code and information about the following:

• PDS Methods XML

• Using SOAP to call PDS methods

• Programmatic logon to Microsoft Project Server

• PDS usage and methods reference

• Error Codes
