I was able to make it work. I have a server subfolder with Python Flask app and I wanted to deploy it automatically using GitHub integration.

Heroku uses buildpacks to detect the language & framework of your project. More about that here.

I found the source code for my buildpack here. Then you just need to look at the detection script. For python it checks the requirements.txt file, so I made a symlink using ln -s server/requirements.txt requirements.txt.

My Procfile looks like this: web: gunicorn --pythonpath server/api app:app.

Everything works now!
