The tutorial to build the game is very simple and easy to follow. However, what I did not understand is how the gamification system/game I develop integrates into my application/website/app. What do I need to do for this? Are there any tutorials around it?

Hi Gopalakrishnan,

Welcome to the playlyfe forums!

You can integrate the game into your app by using our REST API. You can read user profiles, trigger actions, view learderboards,etc, by just making simple api requests from your app.
There is small blog series available that walks you though the process of integrating playlyfe into a simple todo app. You can find that here:

In case of any further queries, do get back to us. We are in the process in improving our documentation and integration guides, so any feedback would be welcomed.

Also, just wanted to let you know of our interactive developer documentation where you can make api requests to your game . You can see it in action in the video below (at 1:43).
