Other relevant information; there may be a different/better way to do this:

When importing played states from Trakt, the PlayCount=1 and Played=true. However, the LastPlayedDate field is missing.

Code:

['UserData'] from server before POSTing update:
{
    "PlaybackPositionTicks": 0,
    "PlayCount": 1,
    "IsFavorite": false,
    "Played": true,
    "Key": "528085"
}

I am using a script to delete media after certain conditions are met. The script needs to know when the media item was last played for a given user. To account for this; when a media item imported from Trakt is found that does not have LastPlayedDate, the current date-time is used. The script then uses this date-time to determine when the media item should be deleted.

Code:

Expected ['UserData'] from server after POSTing update:
{
    "PlaybackPositionTicks": 0,
    "PlayCount": 1,
    "IsFavorite": false,
    "Played": true,
    "Key": "528085",
   "LastPlayedDate": "2024-01-03T12:10:03.000Z"
}

Also tried toggling the Played field (True --> False --> True) to get Jellyfin to populate the date-time. But get the same 404 Not Found - HTTPError.

My issue was using GUI generated API keys instead of Authenticating By Username via the API endpoint

Code:

/Users/AuthenticateByName

I had a very similar issue and in debugging (after seeing your comment above) I did switch from using the API key to AuthenticateByName - but I still had issues with the PlaybackPositionTicks not updating.

What I found to be my solution was to use the endpoint /UserItems/{itemId}/UserData and post the updated UserData there. Then I found that all the UserData is updated, including the PlaybackPositionTicks
