Quick start
This guide helps you make your first request to the VerifyVAT API in just a few minutes. If you haven't done so yet, create an account and log in.
First, go to the Profile › API Access section and copy your access key. You will need this key to authenticate every request. Keep it safe: anyone who has it can use it to consume your credit.
Once you have the key, you can query the main endpoint. The API accepts both GET and POST requests. The recommended method is POST, so you can pass parameters in the request body.
Prepare your POST call:
POST https://verifyvat.com/api/:tax-type/:tax-idContent-Type: application/jsonx-api-key: {api_key}You can find a list of supported tax types in the Parameters section, or use auto to let the API detect the correct type automatically.
If your application does not support POST queries, you can still use GET, but you will need to pass the parameters as a query string. Some advanced features may not be available in this mode.
Make the request. If everything is correct, you will receive a 200 OK response with the requested data.
The response will be in JSON format. Here is a sample excerpt of a successful response for IT00743110157 (Tax type: it_vat):
