Security Best Practices

• -Store API keys in environment variables. Never commit keys to version control.
• -Rotate keys periodically from the Developer Portal.
• -Use server-side requests. Never expose your key in client-side JavaScript.
• -If a key is compromised, revoke it immediately from the Developer Portal and generate a new one.
