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.

Field reference

The fields used in the api. http://world.openfoodfacts.org/data/data-fields.txt

JSON interface

Countries

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

A few things to note:

Reading a product

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

Fields within a product

Categories

The categories_hierarchy is sorted by the "level" of each category. Level 0 means the category has no children, level 1 means it has children that do not have other children, level 2 is when it has children that have children that do not have children etc.

Posting photos

  • Use the POST method on /cgi/product_image_upload.pl
    • code: the barcode
    • imagefield: (front | ingredients | nutrition)
    • imgupload_front : your image file if imagefield:front
    • imgupload_ingredients: your image file if imagefield:ingredients
    • imgupload_nutrition: your image file if imagefield:nutrition

Important:

  • there must be a HTTP header "Content-Type: multipart/form-data" in the HTTP POST request.
  • the imageupload_(front|ingredients|nutrition) name, size and data needs to be encoded in the multipart/form-data format, usually your HTTP request library will do that for you
  • all parameters need to be passed as POST parameters, do not put some in the URL
