  title: Foodsoft API v1
  version: '1.0.0'
  description: >
    [Foodsoft](https://github.com/foodcoops/foodsoft) is web-based software to manage
    a non-profit food coop (product catalog, ordering, accounting, job scheduling).


    This is a description of Foodsoft's API v1.


    Note that each food cooperative typically has their own instance (on a shared
    server or their own installation), and there are just as many APIs (if the Foodsoft
    version is recent enough).
    This API description points to the default development url with the default
    Foodsoft scope - that would be [http://localhost:3000/f](http://localhost:3000/f).

    You may find the search parameters for index endpoints lacking. They are not
    documented here, because there are too many combinations. For now, you'll need
    to resort to [Ransack](https://github.com/activerecord-hackery/ransack) and
    looking at Foodsoft's `ransackable_*` model class methods.
