+The API (Application Programming Interface) is the way an application can enter in dialogue with Open Food Facts application server.
-== Introduction ==
+All information about the API can be found [https://openfoodfacts.github.io/openfoodfacts-server/api/ in the documentation].
-=== Current status of the API ===
-* Currently the API is used internally for the official Open Food Facts mobile applications (iOS, Android, Windows, and we need help !) and by dozens of reuses on various topics (Nutrition, sport…) and platforms (iOS, Android…), but does not yet follow good practices in API design.
-* It is also used by several applications 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
-** https://github.com/openfoodfacts/cordova-app/blob/master/www/index.html
-* '''Anyone with Swagger (or equivalent knowledge) willing to help us document the API is most welcome :-)'''
-=== Getting help with the API ===
-You can ask for help on using the API in this [https://openfoodfacts.slack.com/messages/api/ API channel on Slack]. Join us to discuss your use case and get help/code from other devs.
-=== How to test the API ===
-==== READ operations ====
-===== Technical details =====
-* You can do READ operations using production
-* You should now use the SSL version of the API. The unsecure version '''WILL''' be deprecated :-)
-<pre>https://ssl-api.openfoodfacts.org</pre>
-===== Licence =====
-Open Food Facts is under the OdBL licence (database) and CC-BY-SA (pictures). That has a couple of legal implications. Please join us on the Slack channel to discuss them.
-==== WRITE operations ====
-===== Use cases =====
-* You can add photos and informations to Open Food Facts using the API.
-** Letting your users add new products by uploading photos is the most common use case.
-** Several apps already enable more advanced editing. Gamification would be welcome.
-* The official mobile apps can use some help.
-===== A few things =====
-* Do join the API channel if you intend on using WRITE
-* Do not send copyrighted photos or information using the API. Everything you send is OdBL for the data, and CC-BY-SA for the pictures. If those are not yours (eg from scraping), you bear all the legal consequences.
-* You can create a global account for your app if you don't want to implement Open Food Facts user creation in your app right now. Please report it in #api so that it can be monitored for errors.
-* You should do all your test edits on https://world.openfoodfacts.net (ask for the password on Slack)
-=== Conventions for the API ===
-* fields that end with _t are dates in the UNIX timestamp format (number of seconds since Jan 1st 1970)
-* fields that end with _datetime are dates in the iso8601 format: yyyy-mm-ddThh:mn:ssZ
-* fields that end with _tags are comma separated list of tags (e.g. categories_tags is the set of normalized tags computer from the categories field)
-* fields that end with a language 2 letter code (e.g. fr for French) is the set of tags in that language
-* fields that end with _100g correspond to the amount of a nutriment (in g) for 100 g or 100 ml of product

-=== Roadmap ===
-[[API/Roadmap]]
-=== Bugs ===
-==== Reporting bugs ====
-* Do not hesitate to file a bug if you find an issue in the API, or need an improvement.
-==== Known bugs ====
-* General bugs: https://github.com/openfoodfacts/openfoodfacts-server/issues
-* API bugs: https://github.com/openfoodfacts/openfoodfacts-server/labels/api
-* API milestone: https://github.com/openfoodfacts/openfoodfacts-server/milestone/8
-=== Warning ===
-* Some products are incomplete.
-* You should ensure your UX tells the final user that the product is not complete, encourage them to exercise caution and/or help complete the product.
-* When doing averages, computations… filter incomplete products to avoid issues
-* Assume the data is not reliable until the product is marked as complete.
-* In general, ensure the user exercises maintains caution (for allergens…) and be upfront about possible risks.
-== READ API Documentation ==
-=== Downloading static data ===
-It is recommended to use the live API to get fresh data about products, the minute they are uploaded to the database. However, in some cases, you may need a snapshot. They are available at:
-* https://world.openfoodfacts.org/data (all data)
-* https://fr.openfoodfacts.org/data (data for that country)
-==== CSV API ====
-The character that separates fields is <tab> (tabulation).
-===== Encoding =====
-The file encoding is Unicode UTF-8.
-==== MongoDB dump ====
-=== Field reference ===
-The [[fields used]] in the api.
-https://world.openfoodfacts.org/data/data-fields.txt
-=== JSON interface ===
-=== Pagination of results ===
-If you're looking for all products within a facet (eg: https://fr-en.openfoodfacts.org/category/pizzas.json), you'll only have the 1st page.
-To move from page to page:
-<pre>
-https://fr-en.openfoodfacts.org/category/pizzas/1.json
-https://fr-en.openfoodfacts.org/category/pizzas/2.json
-</pre>
-=== Countries and Language of the Response ===
-You can either use the global (https://world.openfoodfacts.org, https://ssl-api.openfoodfacts.org) or local (https://fr.openfoodfacts.org,https://en.openfoodfacts.org…) domains for your API queries
-====A few things to note====
-* if you use a country subdomain instead of world, you get products for that country only, which might change the language but also the name of the fields. In that case you need to use the local language.
-** https://fr.openfoodfacts.org/categorie/pizzas.json
-* an alternative to avoid dealing with local languages is to specify the language in the subdomain: https://fr-en.openfoodfacts.org/category/pizzas.json
-==== Country code (cc) and Language of the interface (lc) ====
-By default, the country code (cc) and language of the interface (lc) are set through the subdomain.
-===== Examples =====
-# https://world.openfoodfacts.org --> cc = world, lc = en (default language for the "country")
-# https://fr.openfoodfacts.org --> cc = fr (France), lc = fr (French)
-# https://jp.openfoodfacts.org --> cc = jp (Japan), lc = ja (Japanese)
-# https://ch.openfoodfacts.org --> cc = ch (Switzerland), lc = de (German, set as main language for Switzerland)
-# https://ch-fr.openfoodfacts.org --> cc = ch, lc = fr (French)
-==== Over-riding Country code (cc) and Language of the interface (lc) using cc and lc parameters ====
-If you pass ?cc=us and/or &lc=it, it will set the country to US and the language to Italian
--> if you just pass cc, the lc will be the one set in the subdomain.
-e.g. world.openfoodfacts.org + cc = fr --> cc = fr, lc = en (default language of world)
-The cc affects which results are returned. cc = fr -> you get only products with France listed in the countries where sold field.
-The lc affects the language in which results will come back.
-If the results include links to products, those links will use a new subdomain that corresponds to the overrides.
-=== Reading a product ===
-The requested subdomain will be the locale fetched. (fr.openfoodfacts will fetch FR, world.openfoodfacts EN, world-fr FR products from the whole world)
-==== Structure of the call ====
-* https://world.openfoodfacts.org/api/v0/product/737628064502.xml
-* https://world.openfoodfacts.org/api/v0/product/737628064502.json
-The final number must be a valid barcode.

-==== Nutrition values ====
-===== Nutrition data =====
-====== General structure ======
-The nutrition facts are presented by multiple fields per nutrition fact. Each nutrition fact is presented by a key, i.e. "salt", "fat", etc. The fields can also be found in the taxonomy translation file.
-The fields can have the following structure:
-* key (string) - the value for the nutrition fact key (eg in json: "fiber":"0.5");
-* key_serving (string) -  the value of a serving for type key (eg: in json "carbohydrates_serving":"5.82"). The size of the servig is found in the serving field;
-* key_value (string)  - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
-* key_100g (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
-* key_unit (string) - the units used in the other fields (eg in json: "carbohydrates_unit":"g"). Possible values are "kg", "g", "mg, "µg", "l", "ml", "%" or "";
-* key_label (string) - a more user friendly text explaining the

-== WRITE API Documentation ==
-=== Status Codes ===
-==== If the edit was successful ====
-<pre>
-{"status_verbose":"fields saved","status":1}
-</pre>
-==== If there was an issue ====
-===== Wrong password =====
-HTML 200 code + an HTML page with a link to login
-Example: https://world.openfoodfacts.org/cgi/product_jqm2.pl?code=0048151623426&user_id=usernameexample&password=*****&product_name=KIRI%2
-=== Authentification ===
-* user_id
-* password
-WARNING: If the password is not correct, the API will currently "silently" fail, both for image addition and product data addition (will return HTML 200 code + an html page with a link to login - [https://world.openfoodfacts.org/cgi/product_jqm2.pl?code=0048151623426&user_id=usernameexample&password=*****&product_name=KIRI%2 example] )
-==== Anonymous contribution ====
-* It is possible for new products (no anonymous modification is possible though, for obvious reasons)
-* It is possible for adding images (as many as you like)
-* If you detect an error 200 (wrong password), please retry the query without user_id and password. That way the contribution will be accepted. Otherwise, the photo will get lost :(
-==== Global account ====
-If you want to avoid coding the detection of password errors, login stuff… you can create a global account for all your users.
-You can create a global account to let the users of your app contribute. please name it YourApp_app or something like that, so that we can spot them easily. Better yet, introduce yourself on Slack :-)
-=== Manipulating photos for a product ===
-==== Understanding products and photos ====
-* Photos are the primary source of Open Food Facts.
-* We need good photos or the '''product''', of its '''ingredients''' and '''nutrition table'''. (and for each language present on the packaging)
-* Please encourage your users to add as many photos as possible, even if the product is already complete (in that case, don't set them as default photos for  front, ingredients, and nutrition)
-==== Upload behaviour ====
-If you upload an image (eg for front), the first one will be shown, the others will be saved but not displayed. Useful if you want to let your users take additional images that are neither front, ingredients or nutrition (eg: recycling instructions, labels…)
-==== Understanding photos for multilingual products ====
-Multilingual products have several photos based on languages present on the packaging. Just suffix the lang code to our examples to get or add the relevant language(s).
-==== Adding photos for a product ====
-* Use the POST method on:
-<pre>Test server: https://world.openfoodfacts.net/cgi/product_image_upload.pl</pre>
-<pre>Live server: https://world.openfoodfacts.org/cgi/product_image_upload.pl</pre>
-<sup>(remember to do tests on world.openfoodfacts.net - login and password: off )</sup>
-===== Parameters =====
-* 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
-===== Example =====
-<pre>
-curl --user off:off --form "imgupload_front=@Tacitus.jpg" --form code=1212121212 --form imagefield=front --form user_id=tacite  --form password=mypassword https://fr.openfoodfacts.net/cgi/product_image_upload.pl</pre>
-=====Important=====
-*  Content-Disposition: form-data; name=“imgupload_front”; filename=“front.png”
-* 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.
-* 0048151623426 is a random barcode used only for demonstration purposes.
-==== Getting a list of all available photos ====
-You get a list of all available photos in the product JSON (both selected photos for all languages, and Raw photos (source images for the selected images and images that are not used)

-==== Cropping a photo ====
-This implies applying operations to a source image (not only cropping, but all the others if applicable). We start from a source image (defined by a barcode and incremental id), apply cropping parameters (x1, y1, x2, y2), additional operations (white_magic, normalize)

-==== Performing OCR on a photo ====
-We start from a source image (defined by barcode and id) as selected for ingredients. We ask Product Opener to process it (process_image=1). Product Opener returns a JSON. Processing is done using Tesseract (3 on preprod). The result is often cripped with errors. Take steps to avoid direct copy pasting into the ingredients field by your users.
