These bots are deployed at heroku, where only one so-called dyno is for free. Hence one backend is used for all my bots.

1. First of all, update pipenv and start the local heroku server.

   # update pipenv
   source ./utils/prepare_deployment.sh "<telegram-bot-api branch>"
   
    # start local heroku server
    pipenv run heroku local

2. Then make the local heroku server available via ngrok:

   ngrok http 5000

3. Update the telegram bots' webhooks using environment variables. pipenv is used for the right environment variables, which can be set in a local .env file.

   # update webhook in .env
   
   pipenv run python utils/set_webhook_to_ngrok.py

1. Update pipenv using the following script.

   # update pipenv
   source ./utils/prepare_deployment.sh "master"

2. Set the webhook to heroku, not to ngrok.

   pipenv run python utils/set_webhook_to_heroku.py

3. Push to master since heroku automatically deploys from github.
