If you are a game studio or publisher and your Steam app meet the requirements, you may be eligible to claim your game on Discord. Claiming your game on Discord will allow you to customize the profile of your game, meaning you will have a lot more control over how your game is presented on Discord.

Next to being able to update the game's description, add media, info, and links, you also get that sweet, sweet Verified™ checkmark on your server icon to show your community you're the real deal.

Prerequisites before applying

• Your development studio must have a Discord server.
• Your game must be on Steam, and the Steam store page must link to your Discord server.
• Your game must be playable, meaning it’s available for download and play.
• You need to create a Team in the Discord Developer Portal.
• You need to create a new application or utilize an existing one in the Developer Portal. 
• The server owner must be on your Developer Portal Team, since they’ll receive a
  verification code that’s required to include during the application
  process.

Submitting the claim Before Applying

• Head to the Discord Developer Portal and open your game's Developer Portal application.
• On the left sidebar, select Game Identity under Games, then click Claim Game.
• Search for your game title and select it.
• Fill out the Game Claim Verification form.

During the process, Discord will send a verification email to the server owner.
