I am not a mac/Unix user, Don’t know about vi and all. How can I deploy my flask app to Heroku from w i n d o w s os and how things work when we use gunicorn-server. Its server runs on 127.0.0.1.8000 and when we deploy our flask application to heroku, why it is showing Hello!, since it is implemented in route ‘/’ but webhook() function is defined in route f’/{TOKEN}’ which is returning Ok. The video is not clear at all.
