Integrate with Paperless-ng
What is Paperless-ng
Paperless-ng is an application that indexes your scanned documents and allows you to easily search for documents and store metadata alongside your documents. It was a fork from the original Paperless that is no longer maintained.
This setup uses HTTP headers to log you in simply by providing your username as a header. Your authentik username and Paperless username MUST match. If you intend for this to be accessed externally, this requires careful setup of your reverse proxy server to not forward these headers from other sources.
The author of Paperless-ng recommends you do not expose Paperless outside your network, as it was not designed for that. Instead, they "recommend that if you do want to use it, run it locally on a server in your own home."
