Setting Up Google Maps
To use the Maps module, you'll need to create a Google Maps API key.
Google has made this much more complicated recently and Google Maps now requires a payment profile in order to use their service. However, unless you have a very high-traffic site, you will likely fall within their free tier.
Their pricing is free up to 25,000 map loads per day, then $0.50 USD / 1,000 additional map loads per day thereafter.
To get your API key:
Step 1
Go to Site Settings > API Keys and follow the link in the Google Maps API Key info box.
Step 2
Click Get Started in the Google Get API Key link.
Step 3
Check all three boxes to enable the Google Maps Platform, then click Continue.
Step 4
Select an existing project, or create a new project, then click Next.
Step 5
If you created a new project, you can name it whatever you'd like, then click Next.
Step 6
Now you'll create a new billing account. Again, you will get 25,000 daily map loads for free. Click Create Billing Account.
Step 7
Agree to the Google Cloud Platform terms and click Agree and Continue.
Step 8
Create a new payment profile, or choose an existing payment profile.
Step 9
You will be prompted to create an API key - click Next.
Step 10
Finally, you have your API key. Paste that value into Site Settings > API Keys > Google Maps API Key (shown in Step 1)
You can now use the Maps module.
