Transmission Torrent Notifications Email/Prowl

Can someone help me?
I am looking for a script that will send me an email and/or send a prowl notification when torrents finish.
I have tried lots of different scripts and I can't get them to work.

This is my code from the settings.json

"script-torrent-done-enabled": true, 
    "script-torrent-done-filename": “/data/Transmission/config/transmission_complete.sh”,

This was the script code I was trying to use, but I wasn't working.

#!/bin/sh
/bin/curl -k -F apikey=[your Prowl API key here] -F application=Transmission -F event="Download Complete" -F description="$TR_TORRENT_NAME completed on $TR_TIME_LOCALTIME" https://api.prowlapp.com/publicapi/add

and also this one

#!/bin/sh
/opt/bin/curl -k https://prowl.weks.net/publicapi/add -F apikey=[replace with your growl API key] -F priority=-1 -F application="Transmission" -F description="$TR_TORRENT_NAME completed on $TR_TIME_LOCALTIME"

And this one:

#!/bin/sh

curl -k https://prowl.weks.net/publicapi/add -F apikey=[replace with your growl API key] -F priority=-1 -F application="Transmission" -F description="$TR_TORRENT_NAME completed on $TR_TIME_LOCALTIME"

# /bin/curl -k -F apikey=[your Prowl API key here] -F application=Transmission -F event="Download Complete" -F description="$TR_TORRENT_NAME completed on $TR_TIME_LOCALTIME" https://api.prowlapp.com/publicapi/add

I did see this post by the master (super-poussin), wondering if that still works, because the new R6 doesn't have the addons-config folder.

Another question if anybody knows, how do I change the web client skin on transmission readynas, I have new skin files, I want to backup the old ones, but I cant find them.

I can use SSH.
Please help a noob out.
