VATify.eu offers a „demo“ API which can be used for testing during
development. To access the demo API, use slightly different URLs than the
demo/ path component must be inserted after the
For example, click here to search for data about a swiss company:
The JSON response will contain the ID of a VATify.eu query that was just started, as well as an API endpoint URL that you should poll for results. Open this URL in your browser to check the query status and (if already available), obtain the resulting company data.
The demo API is absolutely free to use.
The demo API can be used without authentication. You don't even need an API account. Your requests will work as if you had already authenticated and obtained the authorizing bearer token.
The demo API accepts HTTP GET requests where other methods, such as POST, would otherwise have been required. It also accepts query string parameters instead of a JSON-formatted request body. This is to allow testing with only a web browser.
However, the demo API is limited to this demo list of companies. Searching for any other business ID will result in a NOT_FOUND status, indicating a non-existent company.
Also, the demo API returns old/stale data which may have been collected many days ago.
