Status

Currently the API is mainly used internally for Cordova application, but does not follow good practices in API design. It is also used by several application and while not yet stable, doesn't change much. You can ask for help on using the API in this [channel]. You can have a look at the source code of the app (https://github.com/openfoodfacts/cordova-app/blob/master/www/off.js and https://github.com/openfoodfacts/cordova-app/blob/master/www/index.html)

Testing

  • You should do all your test edits on http://world.openfoodfacts.net (ask for the password on Slack)
  • Do not hesitate to create a global account for your app if you don't want to implement Open Food Facts user creation in your app right now.

API Basic Documentation

Countries

You can either use the global (world) for locales (fr, en…)

Reading a product

See http://fr.openfoodfacts.org/data or http://en.openfoodfacts.org/data The requested subdomain will be the locale fetched.

Searching for products

You can add &jqm=1 to search results pages on the web site to get results in a jquerymobile format.

Also:

  • sort_by=unique_scans_n
  • page_size=50 (20 by default, 1000 at most)
  • page=2

Example: (remember to do tests on .net)
