Where PMS_IP is your PMS ip address and key is the key value of the video file, however it does not update the watched status. What is the correct way to do this.
Yep, thanks, already figured it out. The links I posted were worng because the plex forum screwed them up :( Just like your first link ;)
However my problem was I was passing the key value from the library when it actually needs the ratingKey. Nice confusing naming there by the way. key in the http request and ratingKey in the library ;)
