Radarr
The radarr native integration allows you to add your radarr instances that are available publicly on the internet to your listrr account. The added radarr instances can be used to add your lists automatically via the Custom Lists feature available in radarr.
This feature makes it easier for users with many lists to automatically add them to their instances without manually adding each list one by one.
