Quick Start Guide
Get TraceKit running with your application in just a few minutes.
Step 1: Generate an API Key
Every application sending traces to TraceKit needs an API key for authentication.
Navigate to API Keys in the dashboard
Click "Generate New Key"
Give your key a descriptive name (e.g., "Production Backend")
Copy the key immediately - you won't see it again!
Important Security Note
Store your API key securely. Never commit it to version control. Use environment variables instead.

Once configured, your traces will start appearing in the TraceKit dashboard automatically.
