Google places import on wordpress

I have a theme that I buy on themeforest for a directory on wordpress. With it there is a way to import places from google places. but its complicated. I have another directory theme where you can do it easily. here is the video : [login to view URL] So I would like to create this page on my directory so I can do it as on the video. For that I will give you the code they use to do it so you can inspired you and adapt it on my website.
