Company rest API

Trade register document

The API returns company's trade register document in PDF format, as specified by business ID or duns number.

In order to use the API you must have the valid environment-specific username and password. Before any API requests, you need to obtain an API KEY. You will get a valid API KEY (it's called a ticket) by using the ticket API (Please, read how to use ticket API instructions).

The API KEY must be sent in the request custom header element (named ticket or x-api-key). If the API KEY value is valid then API request will be successful (http status code 200), otherwise it will fail (http status code 401). All API requests must be made over HTTPS. Request the username and password
