Google Maps API integration into Forms

Google Maps API integration into Forms

I looked around a good bit and could  not find anything on this topic. I was curious about using the Google Maps API on a Zoho Form. Specifically an order form for a product that we will only deliver within certain City Limits. We currently use the API to call the exact address (as dictated by Google) and if the City name does not match where we service it is very evident. (Using FormCraft Form in Word Press) The "exact address" name is also used later in the process as well. 

I do not see a way to integrate the Google Maps API into a Zoho Form. Any thoughts or advice would be welcomed.
