Changes in Google Maps API policy
Starting June 11, 2018 Google requires that all requests to Maps API use an API key. Moreover from July 16, 2018 billing must be enabled for the project associated with the API key. This guide will explain how to set up the project, enable billing and generate API key, which you can then enter in the GeoIP plugin configuration and enable displaying of your online visitors on the map.
Setting up Google Cloud Platform project and billing
Assuming you already have a google account, and you are logged in, go to https://console.cloud.google.com/home/dashboard and read and "Accept" the updated terms of service.
Then if you don't have any project, click "Create" to create a new project.
You can name it whatever you like, then click "Create"
You also need to enable billing for the project. Click on the "Link a billing account" or select an already set up account. You will be asked to enter your personal data and credit / debit card information.
Adding Google Maps API to your project
Then on the next page click "Enable". This will add the Maps API to your project.
Creating and configuring Google Maps API key
Click "Create credentials" and select "API key" and then "Restrict key" to set up how the API key can be used. It is good idea to limit the API key use to the domain where your LiveAgent is installed to prevent unauthorized API key use from any other domain.
