API Keys

API keys connect your app to the burn0 dashboard. Each key is linked to a project and your user account.

​
Creating a key

  1. Go to burn0.dev/dashboard/keys
  2. Click “New key”
  3. Enter a name (e.g., “dev laptop”, “staging”, “production”)
  4. Optionally set a project name
  5. Copy the key immediately — it’s only shown once

​
Key format

b0_sk_a1b2c3d4e5f6a1b2c3d4e5f6a1b2c3d4
Keys start with b0_sk_ followed by 32 hex characters.

​
Using the key

Add it to your project’s .env file: 
BURN0_API_KEY=b0_sk_your_key_here
Or use the CLI: 
npx burn0 connect

​
Multiple keys

You can create multiple keys for different environments:
Key nameProjectEnvironment
dev laptopmy-appLocal development
stagingmy-app-stagingStaging server
productionmy-appProduction
Each key’s events appear separately in the dashboard, grouped by project name.

​
Revoking a key

Click “Revoke” next to any key in the dashboard. The key is deactivated immediately — any SDK using that key will get 401 errors. Revoked keys cannot be reactivated.
Revoking a key cannot be undone. Create a new key if you need to re-enable tracking.

​
Security

  • Keys are shown in full only at creation time
  • The dashboard only shows the first 10 characters
  • Add .env to .gitignore to prevent accidental commits
  • burn0 init and burn0 connect add .env to .gitignore automatically
