Validate VAT numbers automatically via an API
If you have a self-developed billing system or shop system and you check VAT numbers on a regular base, we have an API-connector available. This connector allows you to automatically check VAT numbers from your own system.
If you register for this webservice, you can choose how many checks you need per day. You buy the checks in advance for a certain period. You can increase the number of checks and months at any time.
How does it work?
You sign up for 50 checks per day and pay €14,50 a month. You can check up to 50 VAT numbers a day with the API. If you run less than 50 checks per day, the remaining checks will expire. Unused checks are not transmissible to the next day.
For each checked VAT number with a positive or negative result one check is deducted. When a validation fails, , there will be no check deducted. The result of each validation will return via the SOAP interface. If you log into your account you'll get a list of all VAT numbers checked that day and, if necessary, you can increase the number of checks per day immediately.
Are you interested in using our API-connector? Please register here. Further instructions and documentation are to found on the website after registration.
