# About the Partner WSDL

The Partner Web Services WSDL is used for client applications that are metadata-driven and dynamic in nature. It’s particularly—but not exclusively—useful to Salesforce partners who are building client applications for multiple organizations.

As a loosely typed representation of the Salesforce data model that works with name-value pairs of field names and values instead of specific data types, it can be used to access data within any organization. This WSDL is most appropriate for developers of clients that can issue a query call to get information about an object before the client acts on the object. The partner WSDL document needs to be downloaded and consumed only once per version of the API.

For more information about the Partner WSDL, see [Using the Partner WSDL](https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_partner.htm) in _SOAP API Developer Guide_.
