If you’ve chosen Google Maps as a route provider in Zapiet - Rates by Distance, you’ll need to set up your API key and add it into your settings.
Google provides a free trial of 90 days, or until $300 USD of credit has been used. After the free trial, they provide $200 USD of free credit per month which is more than enough for most merchants.
Should you exceed their free limit, you will be charged for your usage. View their plans and pricing for more information.
