To use the IMPORTGMMAP and IMPORTGMPTS plugins with Google Maps data, you need to have a Google API access key for the services listed below:

The keys that came with the plugins will no longer work due to abuse by certain users. Therefore, to use these plugins, the user must have their own keys.
Check out the step-by-step guide below on how to obtain a Google Maps API key:
1 - Log in or create a Gmail account
First, to obtain a Google Maps API key you will need to have a Gmail account. If you don't have one yet, you can create one for free by clicking on the link below → [Create a Gmail account].
2 - Access the Google API Console dashboard
Click this link: (https://console.cloud.google.com/apis)
The page may be in Portuguese, in my case, it came in English, so just pay attention.
3 - Create a new project by clicking "Select a Project":

A screen like this will appear:

Read the terms of service and accept them by clicking the "I Accept…" box
Note: it may be in YOUR LANGUAGE!
Click to create a project:

Enter a name, then click the "Create" button:

Now you have a project created, called "my project":

4 - Select the APIs to be enabled, by clicking on "Library", or "Biblioteca":

When choosing the APIs you will use in the library, later on, you will be able to mark them when creating the access key, so don't skip this step!
Now, search for Maps Static API:

Click the Maps Static API box, and the following screen will open. Click Enable:

When you click Enable, you should be directed to the credit card configuration screen
5 - Add a payment method
Before you ask me: "Oh, but will I have to pay Google to use the plugin????"
First, you have to read the terms of service. There you will know that there is a free quota. You will only be charged if you exceed this quota. And how big is this quota? It's big enough that one person can't get through it.
I had to block the keys I made available because there were THOUSANDS of people using it at the same time.
Then on the following screen:
(again: it might be in YOUR LANGUAGE!)

Click on Agree & Continue, then on Create new payment profile:

On the next screen, you must enter your details:

Now, enter your address:

Now you will need to enter a card:

When you click on "Add payment method", you will see:

Click on Add credit or debit card
