== Status ==
+
The API (Application Programming Interface) is the way an application can enter in dialogue with Open Food Facts application server.
−
Currently the API is mainly used internally for [[Project:Mobile_Apps|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 ==
+
All information about the API can be found [https://openfoodfacts.github.io/openfoodfacts-server/api/ in the documentation].
−
You can ask for help on using the API in this [[https://openfoodfacts.slack.com/messages/api/|API 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.
 
−
== Bugs ==
 
−
* Do not hesitate to file a bug if you find an issue in the API, or need an improvement.
 
−
* https://github.com/openfoodfacts/openfoodfacts-server/issues

== READ API Documentation ==

=== Static data ===
 
−
http://world.openfoodfacts.org/data
 
−
=== Field reference ===
 
−
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:
 
−
* 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.

=== Searching for products ===
 
−
==== General principles ====
 
−
===== Advanced Search =====
 
−
====== Parameters ======
 
−
You can basically use all the parameters you'd use in a [http://world.openfoodfacts.org/cgi/search.pl?action=display&sort_by=unique_scans_n&page_size=20&action=display graphical advanced search on the site]<br>
 
−
* sort_by=unique_scans_n
 
−
* page_size=50 (20 by default, 1000 at most)
 
−
* page=2
 
−
* jqm=1 to search results pages on the web site to get results in a jquerymobile format.

===== Examples<sup>(remember to do tests on world.openfoodfacts.net - login and password: off )</sup> =====

−
===== Generic Search =====
 
−
====== Combining Tags to get custom results ======
 
−
Combining tags works, letting you create thousands of APIs
