Your HeyGen username and space ID ready

Click Add to Slack
Select your workspace and click Allow

Step 2: Connect your HeyGen account

After installation, you'll be redirected to connect your HeyGen account:

If you're already logged into HeyGen: Installation completes automatically. You're done!
If you're not logged in: You'll be redirected to HeyGen to log in, then complete the setup by selecting which HeyGen space to use

That's it! The HeyGen bot is now available in your workspace.

How to use

Method 1: @mention the bot

Simply @mention HeyGen with your video idea:

@HeyGen Create a welcome video saying "Welcome to our team! We're excited to have you here."

The bot will:

Acknowledge your request
Generate the video using your HeyGen account
Post the finished video in the thread

Method 2: React with 🎥 emoji

Convert any message into a video by reacting with the camera emoji:

Find a message you want to turn into a video
Click Add reaction (or press R)
Choose the 🎥 :movie_camera: emoji

The bot will use the message text as the video script.

Tip: You can also use a custom :heygen-video: emoji if your workspace has one.

Note: There's a 5-minute cooldown per message to prevent duplicate videos.

Method 3: Curate channel messages

Use the /heygen-curate slash command to find and compile top messages:

/heygen-curate [#channel] [--notify] [--days N]

Examples:

/heygen-curate
/heygen-curate #marketing --days 7 --notify

This will:

Analyze recent messages in the channel (default: last 7 days)
Score messages based on reactions, replies, and engagement
Present the top 3 messages
Optionally notify the thread with --notify

Personal account linking

By default, videos use the workspace's HeyGen account. Team members can link their personal HeyGen accounts to use their own credits and avatars.

Why link your account?

Videos you request will use and be saved on your HeyGen account
You'll use your video credits and your avatars
Other team members continue using the workspace default

How to link your account

Visit your HeyGen account settings at app.heygen.com
Navigate to Connections → Slack
Click Link your Slack account
Sign in to Slack and authorize the connection

Once linked, all videos you create will use your personal HeyGen account.

Check your link status

On the settings menu, Make sure you are on Connections
Check to see if the button is grayed out or says unlink on the Slack card

If the button is grayed out or says unlink, your heygen account and slack accounts are connected.

Unlink your account

To stop using your personal account and switch back to the workspace default:

Go to your HeyGen account settings
Connections → Slack
Click Unlink

Tips & best practices

Writing great video prompts

Do:

Be specific and clear: "Create a welcome video introducing our new design system update"
Include context: "Make a tutorial video explaining how to use the new login flow"
Keep it concise: Aim for 30-90 seconds of content

Don't:

Be too vague: ~~"Make a video"~~
Use very long scripts: Messages over ~500 words may be truncated
Include formatting: The bot uses plain text, not markdown

Using /heygen-curate effectively

The curate command works best with:

Active channels with regular discussion
Time range: Last 24-48 hours typically has the best content
Engagement metrics: Reactions and replies indicate valuable messages

Pro tip: Use --notify in channels where you want to create visibility around the curation process.

Managing workspace credits

To avoid surprise credit usage:

Set up usage alerts in your HeyGen account
Encourage personal account linking for team members who create many videos
Monitor usage in your HeyGen analytics dashboard
