Hi @Joshuv Pullmvn ,
Have you created a widget in another platform and then are you importing it into Kony app?
If yes, then please refer the following documentation:
http://docs.kony.com/konylibrary/visualizer/visualizer_user_guide/Default.htm#Using_Custom_Widgets.htm
The link you are referring to will help you when you are creating/using the native APIs directly in the Kony App.
Hope this helps.
