Steam DLC check

Hello,
we just started using UE4 and are programming games for Steam.
We used before Unity so we did most steam stuff over Plugins…

Well to my question: Im wondering how i can implement the steam DLC stuff to UE4.
Example:

Theres a Steam DLC for my game which is called “Unlock Character”
Logically there locked charaters in my game, which will get unlocked.

BUT how can i check if the player purchased the DLC to unlock it for him ?
And what do i have exacly to upload for the DLC so it gets activated on purchase and so on ?

Sincerely,

Hello, I’m interested in this too, did you find a way to achieve this ?

Use the steamworks SDK to check whether or not a player has this and more!
There is a handy tutorial I use here: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
Assuming you are using 4.7 or later, you won’t even need to download the SDK
