Authentication

The ACME API uses API keys for authentication. Include your key in the Authorization header of all requests.

Getting Your API Key

1. Log in to your ACME dashboard
2. Navigate to Settings, then API Keys
3. Click Generate New Key
4. Copy and securely store your key

Using Your API Key

Include the key in the Authorization header:

Authorization: Bearer YOUR_API_KEY

Example Request

curl -X GET https://api.acme.io/v1/users -H "Authorization: Bearer sk_live_abc123"

Rate Limits

Free tier: 100 requests per minute
Pro tier: 1,000 requests per minute
Enterprise: Unlimited

Exceeding rate limits returns HTTP 429. Implement exponential backoff in your integration.

Key Security

Never commit API keys to version control. Rotate keys periodically. Use environment variables in production. Monitor key usage in your dashboard.
