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 - 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 :-)
