How to Get a TikTok Stream Key for OBS

Get the key (TikTok Creator Academy steps)

1. Log in to TikTok in a desktop browser and click Go LIVE.
2. Add a title (32 characters at most).
3. Turn on the option that stops the LIVE from ending automatically, then start.
4. Copy the Server URL and Stream key into your streaming software.
5. When you finish, end the broadcast from your desktop profile.

Keys expire after a while unused, so generate one no more than about an hour before you go live, and expect a new one each stream.

Put it in OBS

1. OBS → Settings → Stream → Service: Custom.
2. Paste the Server URL and Stream key, then Apply.
3. Settings → Video: Base and Output resolution 1080 × 1920 for a vertical stream (or keep 1920 × 1080; TikTok shows landscape streams with bars or a crop on phones).
4. Add your overlay as a Browser Source at the same size: the vertical Overlay Suite preset is 1080 × 1920.
5. Click Start Streaming in OBS.

No stream key?

Approval for LIVE Studio doesn't always come with a key. If the browser page shows no key fields, use TikTok LIVE Studio (no key needed), or check again later; TikTok grants keys by account and region.
