n6 Portal Backend API

When it comes to the knowledge base, the n6 Portal’s backend API provides the following endpoints: * Table of Contents (GET /knowledge_base/contents), * Article (GET /knowledge_base/articles/<article_id>), * Search (GET /knowledge_base/search).

HTTP responses of the endpoints are strictly dependent on switching on/off the knowledge base (see Initialization and Configuration).
