Places Autocomplete API to get GPS coordinates from address entered

Question

I have an address field in my app where the user needs to enter the required address. I have used google Geocoder to get the GPS coordinates of the address . But now I want to make it easier for the user by using Places Autocomplete . But Places Autocomplete only returns the address , Id and reference of the place .

Is there a way to get the GPS coordinates of the address selected by the user using Places Autocomplete API ? Do I have to use Geocoder again after the user selects his address from Places Autocomplete ?

Or Should I use Places API again after the user selects his address to get the GPS coordinates of the address ? I dont want to send multiple requests to the Places API because of the usage limits in place . . This is the expected response from Places API ..There is no GPS coordinates in the response .

Answer 1

You simply use the Place Details part of the Places API where you get the actual place from the reference in each suggestion using the "reference" value. For example:

https://maps.googleapis.com/maps/api/place/details/json?reference=CiQYAAAA0Q_JA...kT3ufVLDDvTQsOwZ_tc&sensor=true&key=AddYourOwnKeyHere

This will give you information about the place including its coordinates (point for a specific location, bounds for an area).
