I am not familiar with pushbullet, but it is highly probable if you put their below example into "execute - end of print" box it will works.

curl -u <your_access_token_here>: -X POST https://api.pushbullet.com/v2/pushes --header 'Content-Type: application/json' --data-binary '{"type": "note", "title": "Note Title", "body": "Note Body"}'

I can verify that this works:

curl -s "https://api.pushbullet.com/v2/pushes" -u APIKEY_GOES_HERE: -d type=note -d title="LittleRP: Print Complete!" --data-urlencode body="Your print is finished and may be removed from the build platform at this time." -X POST

Make sure to keep the colon at the end of your API key.

I have to say, I'm REALLY liking the Pushbullet integration.  I almost always have my cellphone on me (and I user the web interface to run the printer from my phone) and with this I no longer need to periodically check my printer to see if the print is done.
