The Importance of API Keys

API keys are unique identifiers used to authenticate requests associated with your project or application. They serve several crucial purposes:

  • Authentication: Verifying the identity of the calling application.
  • Authorization: Determining if the application has permission to access the requested resource.
  • Rate Limiting & Quotas: Tracking usage to enforce limits and prevent abuse.

Best Practices for API Key Security

  1. Keep them Secret: Treat API keys like passwords. Never embed them directly in client-side code or commit them to public repositories.
  2. Use Environment Variables: Store API keys in environment variables on your server.
  3. Principle of Least Privilege: Grant API keys only the permissions they absolutely need.
  4. Rotate Keys Regularly: Periodically regenerate your API keys to minimize the impact of a compromised key.
  5. Monitor Usage: Keep an eye on API key usage to detect any suspicious activity.
