Your facebook live rtmp url and stream key are the two details that connect your streaming software to Facebook. Without them, tools like OBS Studio cannot send video to your page, group or profile. This guide explains what they are, where to find them and what to do when something goes wrong.
What Is a Facebook Live RTMP URL?
RTMP stands for Real-Time Messaging Protocol. It is a standard way for streaming software to push live video to a server. When you go live with an encoder instead of your phone camera, Facebook gives you two pieces of information:
- Server URL: the address your encoder sends video to. It starts with rtmps:// because Facebook requires a secure connection.
- Stream key: a long private code that tells Facebook which live video your stream belongs to.
Think of the URL as the street address and the stream key as the door key. You need both for the stream to arrive.
Why Use RTMP Instead of the Phone Camera?
Going live from your phone is fine for quick updates. But a streaming encoder gives you much more control. With it you can:
- Use a professional camera, microphone or screen capture.
- Add overlays, logos, lower-third titles and scenes.
- Stream games, webinars, product demos or church and event services.
- Send the same video to several platforms.
For small businesses, this means a more polished broadcast that builds trust with customers.
How to Find Your Facebook Live RTMP URL and Stream Key
Facebook changes its menus from time to time, so the exact labels may differ slightly. The general steps are the same.
Step-by-step
- Log in to Facebook and go to your page, group or profile.
- Click Live video (usually found in the post creation area or the Meta Business Suite).
- Choose the Streaming software option instead of the camera option.
- Copy the Server URL and the Stream key shown on the screen.
- Add a title and description, and choose your audience.
Keep this page open. Facebook only shows your live preview once your encoder starts sending video.
Persistent vs. one-time keys
Facebook often creates a new stream key for each live video. Some accounts and pages can use a persistent key that stays the same. If your key stops working, the first thing to do is generate a fresh one.
How to Set Up OBS Studio With Facebook Live
OBS Studio is free and popular, so it is a good place to start.
- Open OBS and go to Settings > Stream.
- Choose Custom as the service (or Facebook Live if listed).
- Paste the Server URL into the Server field.
- Paste your key into the Stream Key field.
- Click OK, then press Start Streaming.
- Go back to Facebook, check the preview, then click Go Live.
Before you go live to the public, do a test. You can set the audience to only you or use a private group to check sound and picture quality.
Recommended Settings for a Smooth Stream
Good settings matter as much as the correct facebook live rtmp url. Check Facebook's current requirements in its help centre, since they can change. As general advice:
- Use a wired internet connection if possible.
- Keep your upload speed comfortably higher than your video bitrate.
- Choose a common resolution such as 720p or 1080p, depending on your connection.
- Use a steady frame rate, such as 30 fps.
- Close heavy apps on your computer while streaming.
If viewers report buffering, lower your bitrate or resolution first.
Common Problems and How to Fix Them
Facebook does not show a preview
This usually means your encoder is not connected. Re-copy the URL and key, make sure there are no extra spaces and press Start Streaming again.
The key is invalid or expired
Keys can expire when a live video ends or is cancelled. Go back to the Live video page and create a new one.
The stream keeps disconnecting
Check your internet stability and lower your bitrate. Also try restarting your router and closing other devices that use your bandwidth.
Security tip
Never share your stream key publicly. Anyone with it could broadcast to your page. If you think it has leaked, create a new one right away.
Going Further: Your Own Streaming Presence
Facebook is a great place to reach people, but it is wise to also own your audience. Many businesses publish their live events on their own website too, so viewers can find them through Google. A fast web hosting plan and a good domain name give you a home base for replays, schedules and sign-ups.

Final Checklist Before You Go Live
- Copy the latest server URL and stream key from Facebook.
- Paste them into your encoder without extra spaces.
- Test your audio, video and internet speed.
- Confirm your audience setting and title.
- Start streaming, check the preview, then go live.
Once you know where to find your facebook live rtmp url and stream key, going live with professional software becomes simple and repeatable.

Frequently asked questions
Where do I find my Facebook Live RTMP URL?
Open Live Video on Facebook, choose the streaming software option and the page will show a server URL and a stream key. Copy both into your encoder.
Is the Facebook Live stream key permanent?
Usually no. Facebook often creates a new key for each live video, so check the key again before every broadcast unless Facebook offers a persistent key for your account.
Should I share my stream key with others?
No. Anyone who has your key can broadcast to your page or profile. Keep it private and generate a new one if it is exposed.
Why does my stream not start after I enter the RTMP URL?
The most common causes are a wrong or expired stream key, a typo in the URL, an unstable internet connection or a blocked port. Re-copy the details and test again.
Can I stream to Facebook and my own website at the same time?
Yes, many creators send a stream to Facebook and also embed or restream it on their own site. You need an encoder or service that supports multiple destinations.
