Hey everyone,
Today I've pushed out an update which allows you to include player commissioned unique items within the /itemreleases API call. To use it, simply add include=player_uniques to the end of your request and we'll automatically include them and also add a "player_unique" boolean to each item returned to let you know if it is a player unique or not (so you can distinguish between player uniques and WallaBee uniques, both of which share the collection_id 25).
This all works with the existing since=timestamp parameter so if you are running some form of "new item" alert system, this will allow you see new unique items without constantly hitting the /uniques endpoint.
Shout if you've got any questions.
Ben
