Currently, Google includes all their APIs by default when creating a Google Maps API key. However, for FoodBook, you only need the APIs listed here:

Important Notes:

• Do not enable any extra APIs, as doing so may cause the Google Maps functionality to stop working with the FoodBook system.
• As of March 1, 2025, Google has designated the Directions API as a Legacy service. To ensure compatibility, please enable the following service:
  👉 Enable Places Backend API

Also, make sure you have only the required APIs enabled:

Please double-check that your API key has no application or API restrictions:

🔁 Note: It may take up to 7 days after activation for the API to function properly. Please be patient during this time.
