Navigate to [cloud.google.com](https://cloud.google.com/)

During the sign-up process, you will need to enter your billing information. This is required even for the free trial, but if you stay within the free-tier limits, you won’t be charged.

Enter the domain on which you will be using the map:

Click "RESTRICT KEY"

Head back to SR Contact 01 and check the "Enable API Map" checkbox.

### **Additional Notes:**

- **Billing Information**: Although Google Cloud requires you to enter billing information, you will only be charged if you go beyond the free-tier limits.
- **Free Tier**: Google Maps Platform provides a monthly credit, which is often sufficient for small applications.
- **Usage Limits**: Be aware of the usage limits and pricing tiers for the Google Maps API. Monitor your usage to ensure you stay within the free tier if cost is a concern.
- **API Key**: This API key can be used multiple times across the site, as long as it is used on the domain you restricted it to.
