Answer 1

If someone is still struggling with this, this answer helped me a lot Use Heroku API key.

First, as @Raziza O mentioned in a comment, to get heroku API key

https://dashboard.heroku.com/account. Roll down the screen and hit the reveal button.

Then, just run git push https://heroku:$HEROKU_API_KEY@git.heroku.com/$HEROKU_APP_NAME.git HEAD:master
