4. QUOTA & ALERT SETUP​

Quota Setup​

  • Go to Google Cloud Console → APIs & Services → Quotas.
  • Set limits for:
    • Requests per day
  • Recommended quota limits:
    • Maps JavaScript API: 1000 requests/day
    • For Places API: set limit to 225 requests/day.
    • For other APIs (Maps, Distance, etc.): set limit to 1000, if not setting based on actual usage.
    • Do not exceed 1000 for any API unless necessary.

Alert Setup​

  • Go to Google Cloud Console → Billing → Budgets & alerts.

  • Create budget alerts at:

    • 50% usage
    • 75% usage
    • 90% usage

  • Email alerts to the dev & admin team.

  • �� Set up Budget and Quota Notifications

�� NOTE: Always restrict your API keys to avoid unauthorized usage and unexpected billing.
