Hello. Api usage is very simple. There is list with available calls:

• http://yourshop.com/api/products/bg/get - returns all products with BG translation
• http://yourshop.com/api/product/bg/2/get - return one product with BG translation and id 2
• http://yourshop.com/api/product/set - Set product. Below you can read how the array should be built
• http://yourshop.com/api/product/11/delete - Delete product with ID - 11. Method must be DELETE.

( [translations] => Array ( [0] => bg [1] => en [2] => gr ) [title] => Array ( [0] => текст [1] => text [2] => greek text ) [basic_description] => Array ( [0] => текст [1] => text [2] => greek text ) [description] => Array ( [0] => текст [1] => text [2] => greek text ) [shop_categorie] => 1 [price] => Array ( [0] => 12 [1] => 24 [2] => 20 ) [old_price] => Array ( [0] => 55 [1] => 66 [2] => 65 ) [quantity] => 1 [virtual_products] => [in_slider] => 0 [position] => 1 [image] => image.jpg ) 

You can get another format from api response when set GET FORMAT - ?format=json/array/csv/html/jsonp/php/serialized/xml

You can add authentication when in application/config/rest.php set $config['rest_auth'] to basic/digest/session

This API is not done in order for any vendor to manage its products, it is with full access to all published products.
