Favorites API : adding custom URL entries in Favorites list

Hello,

I have a custom application that uses Favorites API to display/add/remove current node into Portal favorites.

This is working fine.

There is a custom portal application that renders some tiles (like a launch pad) where, when a tile is clicked, opens some  URL in new window or in content area.

Now requirement is to allow user to add any one of these tile's data into favorites list.

I have seen/used the code to add/remove some entry in favorites in many threads on SCN, but all of them add a 'portal node' into favorite.

Here I have to add a custom, non-portal-node type entity (having some text & URL) into favorites.

Could you please let me know how to achieve it?

Thanks & Regards,

Amey
