To broadcast to your Steam store page you need two values: an RTMP upload URL and a stream key, which Steam calls an RTMP token. Both come from one page on the Steam Community site, not from Steamworks, and getting them takes a couple of minutes, without ever sharing your Steam password.
What you need before you start
Steam checks the account that streams, not the software you stream with. That account needs:
▪To be non-limited, which means it has spent at least $5 USD on the Steam store at some point
▪To own the game it is broadcasting
▪The Broadcast Live permission for the app in Steamworks, or membership of the Store Broadcast Beta group. This is the only part set in Steamworks, by someone with admin access to the app.
▪A video to loop: your trailer or a gameplay capture
Create your RTMP token
1.Sign in to Steam as the account that will broadcast and open steamcommunity.com/broadcast/upload.
2.Choose Create RTMP Token. Steam picks an upload server near you and shows its RTMP URL next to your token.
3.Enter your game’s App ID on the same page. Use the base game’s App ID, never a DLC or demo one. It is the number in your store page’s URL, and broadcasting a demo explains why the demo ID hides the stream. 4.Change the broadcast from Friends Only to Public. Friends Only is the default, and it means only you and your Steam friends can see the stream. Your store page shows nothing.
Copy the RTMP URL and the token. The token is effectively a password for your broadcast: anyone who has it can stream to your page, so treat it carefully.
Paste it into Loopcast
In your Loopcast dashboard, create a stream, paste the RTMP URL, the token and your App ID, upload your video and hit start. We store the key on an access-restricted server, never display it again once saved, and use it only to deliver your broadcast.
Troubleshooting
▪Broadcast refused? Check the account first: non-limited, owns the game, and has Broadcast Live permission or Store Broadcast Beta membership.
▪Live, but nothing on the store page? Check the visibility is Public and the App ID is the base game’s, then give it a few minutes: Valve says a new stream can take up to 5 minutes to appear, and the page may need a refresh.
▪Token leaked? Create a new one on the same upload page and update it in Loopcast.

A note on security
Loopcast never asks for your Steam password and never shows your stream key back to you once it is saved. See our Privacy Policy for how your stream key and video are handled.
