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 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)

Getting help with the API

You can ask for help on using the API in this [channel on Slack].

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.

READ API Documentation

Static data

http://world.openfoodfacts.org/data

Field reference

http://world.openfoodfacts.org/data/data-fields.txt

Countries

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

A few things to note:

if you use a country subdomain instead of world, you get products for that countries only which might change the language but also the name of the fields, in that case you need to use the local language
- http://fr.openfoodfacts.org/categorie/pizzas.json
- an alternative is to specify the language in the subdomain: http://fr-en.openfoodfacts.org/category/pizzas.json

Reading a product

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