Authentication

API Key Authentication

Barq uses API keys for authentication. Include your key in every request via the Authorization header.

Bearer Token Format

Authorization: Bearer YOUR_BARQ_API_KEY

Getting Your API Key

1. Sign up at barqapi.com/signup
2. Verify your email address
3. Go to Dashboard → API Keys
4. Click Create API Key
5. Copy and store your key securely — it won't be shown again

Security Best Practices

• Never expose your API key in client-side code, public repos, or screenshots
• Use environment variables to store keys (BARQ_API_KEY)
• Rotate keys periodically — create new keys and revoke old ones
• Set IP whitelists for production environments
• Monitor key usage in your dashboard for anomalies

Example: Environment Variable

# .env
BARQ_API_KEY=barq-sk-abc123xyz...

Key Revocation

You can revoke any API key from your dashboard. Revoked keys stop working immediately. Create a new key to continue using the API.
