The Address AutoComplete API works through HTTP GET requests, so the Address AutoComplete API is cross-platform and you can integrate it into any website or application. The AutoComplete API returns address suggestions for a given address string, while the Place Details API looks for a matching location for a given address. The address autocomplete API accepts a location type as a parameter, so you can generate zip codes, city, country, and other autocomplete inputs. The autocomplete API returns a location ID that can be used to get detailed information about the location and geometry or building boundaries using the Location Information API.

 The autocomplete widget creates a text input field on a web page, provides location predictions in a UI dropdown, and returns location information in response to getPlace() requests. When the user selects a place from the drop-down list, the place information is returned to the autocomplete object and can be retrieved by the application. By default, when the user selects a location from the selection list, the autocomplete feature will return all available data fields for the selected location and charge you accordingly. The Places API web service fires the place_changed event when the user selects a place from the suggestions attached to the autocomplete text field.
