The viesClient.exe client application allows for quick and automatic checking of entities (contractors) from the command line level (CLI / CMD) in terms of their current status in the VIES system. The application also allows you to save the downloaded data to a file in 3 formats:

• JSON (default display format to stdout)
• XML
• MAP (attribute map key = value)

Application has been successfully tested in the following versions of MS Windows: XP, 7, and 10.

The latest version of the application is always available for download from the Download page.

The full functionality of the application can be checked – without the need to create an account – using the provided Test API

To use the add-in in the production API, you need to set up an account on the viesapi.eu website, purchase a minimum of the Business plan and generate an API key and API key identifier.

The process of registering and setting up an account as well as generating keys has been described on the Documentation website.
