IISC, you don't process the incoming updates anywhere in webhook_handler. You'll have to either call dispatcher.process_update(update) or put the update in the dispatchers update_queue if you use dispatcher.start() in order to have the update processed. Also two more notes:

• telegram.Update.de_json(request.get_json(force=True), updater) should be changed to telegram.Update.de_json(request.get_json(force=True), updater.bot)
• if you don't use the updater for fetching updates, you don't need it at all, you just need a Dispatcher

I recommend to have a look at PTBs wiki page about webhooks. There even is a dedicated section on Heroku. Admittedly, it uses updater.start_webhook, but I didn't really see anything in your code that explains why you're using flask instead of the built-in solution.
