Export Google map directions to lat/long - google-maps

Question

I have multiple sets of lat/long coordinates that I am using in the Google directions API with way points to get directions following roads and paths. Each set of coordinates have about 100 points which I am converting to a usable number for the start, end and waypoints.
I would like to get the lat/long values from the directions which are returned from Google. Basically get each coordinate from each road segment.
Is this possible?

Answer 1

Yes, by using the direction API, you would get a respond like this:

Where you can get the lat/lng of each turning points under steps. You can even decode the polyline to get the set of points which describe the road.
