All information about the API can be found [https://openfoodfacts.github.io/openfoodfacts-server/api/ in the documentation].
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 ask for help on using the API in this [[https://openfoodfacts.slack.com/messages/api/|Slack channel]]
 
 
 
== 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.
