# Validated Party Data service
When sending or receiving documents over an e-invoicing network, it is important to be able to identify the parties involved. The Validated Party Data (VPD) service allows for requesting party information so that you can verify that a particular identifier, address, or even tradename does indeed belong to a particular party.
The party data available in the VPD has been aggregated from multiple different sources and is verified by eConnect to be accurate. The data is made available through a GraphQL (opens new window) server endpoint.
Information on how to request party data from this endpoint is detailed in the getting started chapter.
