Participants

This endpoint returns the participants (deltagere) of a company — the people and entities connected to it through roles such as management, board members and founders. It is a focused subset of the full combined company endpoint, without the additional logical groups such as basic information and ownership. Use it when you only need a company's participants and want a smaller, faster response.

Endpoints

The endpoint is api.lassox.com/{lassoid}/participants, where {lassoid} is a Lasso Id for a CVR company. To retrieve the history, add /history to the URL, which wraps each value in an object containing from and to values.

The following is an example of how to get the participants of a specific company. Don't forget to add your API key.
