Developer Guide
One of the following should describe your use case.
You want to do everything on your own
You need to host a server (we use Heroku for this), a database (we use Dropbox for this) and a machine which will run your spooler code (we use a cloud VM running Ubuntu for this). You do not need to do it exactly like us and can use different services.
You want to use our infrastructure to connect your backend
This a bit more complicated because it involves sharing secrets like API keys. We have to discuss internally how we would do this.
