To gain access to the API for your account (your-company-api.sec-hub.com) you need to have an SEC:API agreement with Systems Engineering A/S. When you have that, you will also be given an API Key and an API Secret, which you must use in a standard OAuth2 flow when authenticating with our Identity provider, Auth0.
When you have obtained an Authorization Bearer token from Auth0, you can call the specific API endpoints by providing this token in the request Authorization header.
