What is the product condition?
Snapchat requires merchants to indicate the condition of the products they want to diffuse, that is to say, if they are new, used or refurbished (professionaly restored to working order and that come with a warranty).
You have to indicate this condition (new, used, refurbished) into each product file by going to your PrestaShop back office:
This value is automatically fetched by our module. However, we set up a "replacement value" that is used only if for any reason the condition isn't fetched (which hardly ever happens). This replacement value ensures you that the module will always send a non empty value for the "condition" tag.
So, select the condition that matches the best with the products you sell, and if you don't know what to select, leave the default value (that is "new").
