问题
I have two set of coordinates i.e. one is source and destination. I want to geocode them but in a single shot... not by calling Geocoding API twice. Is there a way this can be achieved ? If not what is the best approach?

Maybe.
If your intent is to find routes between latlngs and have addresses for the origin and destination of those routes, just use the Directions API: https://developers.google.com/maps/documentation/directions/intro
You'll find start_address and end_address in the response. Bear in mind these are the addresses of start_location and end_location respectively, which may not be the latlngs you provided initially.
If your intent is to simply reverse geocode 2 latlngs at once, regardless of the route from one to another, there is just no way to do that in the Geocoding API: just send one request per latlng.
