Google Maps API and APM Planner

Hello to everyone,

I am trying to integrate APM Planner and Google Maps API. Precisely I want to get the elevations of the point in some area by sending them to the Google API and recieving data. But the problem is that I need to it in C+, because APM Planner is implemented in C++. All examples I have found are in python or java. So I would be tahankful to everyone who has some clue how to do this.
