VAT Number Validation API Documentation • Valdit

The API supports a versioning scheme based on including the API major version as part of the URL. Currently version 1 (v1) is the only supported major version. The following format is used for versioning:

{base url}/api/{version}/{resource_collection}/[{identifier_level1}/identifier_level2}]

An example url for retrieving information on a specific VAT number is:

https://api.valdit.com/api/v1/vatnumberchecks/NL/806570994B01

Non-breaking changes to the API may be introduced while maintaining the same major version. Examples of such non-breaking changes are:

*Adding additional non-mandatory fields in the requests to enhance the functionality of existing API Operations
Adding new elements in the response models to provide additional information on the returned resources
Adding new API Operations

An API Client must be capable of handling additional elements in the responses.
