Preview of paste link when authentication required (e.g. project management system)

[tanc]

I'd like to be able to paste a link from our project management system and have the preview text shown under the link in rocket.chat be more relevant. Is there a facility to write some integration code for specific urls? Our project management system (https://taiga.io - self hosted) requires a log in to view a task so I'm not sure how this would work exactly. Any ideas about authenticated pastes or plugins to handle this sort of thing would be great.
