Connections to the Qlik Sense About Service API endpoints are made using HTTPS by default. When communicating with the About Service APIs, the URL is as follows:
https://hostname/<path>
where <path> is an About Service API endpoint.
For example:
https://hostname/api/about/v1/systeminfo
Information noteAccess to the About Service API endpoints requires a valid Qlik session (x-qlik-session). If you attempt to connect without a valid session, a "403 Forbidden" error is returned. Ensure you authenticate before accessing these endpoints.
