However, you're also freed from being dependent on any particular data model or Salesforce.com organization. Consequently, if you use the partner WSDL, you only need to download and consume it once, regardless of any changes to custom objects or fields. Outbound Message WSDL The Outbound Message WSDL document is for developers who want to send outbound messages from a workflow rule or approval process to an external service. Apex WSDL The Apex WSDL document is for developers who want to run or compile Apex scripts in another environment. Metadata WSDL The Metadata WSDL document is for users who want to use the Metadata API to retrieve or deploy customization information, such as custom object definitions and page layouts. See “Understanding the Metadata API” in the Force.com Metadata API Developer's Guide.

You can also download a client certificate for validating requests generated by Salesforce.com.
