Easy integration of chatbot with slack-app - python-3.x

Question

I have a ChatBot application running, just want to hook this application with Slack-api as it's interface.
I used Slack RTM and maintained user-session with its slack user-id.
finally solved and written a client(API) which can easily connect to any conversation engine.
