Nzbget or Grabit

Hello, Need help with Nzbget. Is there a doc that tells how to install and setup for Nzbdrone because when I change from Blackhole to Nzbget it ask’s for an API and a Password? I have left them blank and now I do not receive any shows or if they are there I don’t know were they are. I have been using Blackhole to get the NZB’s then I transfer them to Grabit for download and that works but I have to do the input manually, any help would be great for Nzbget or auto input for Grabit.
Thanks John

You need to use the username and password that is set for the web server for nzbget. If grabit has support for importing not from a folder y an use the with drone 's blackhole support, but to my knowledge they don’t have an API that we can talk to so direct support is not possible.
