Feed types: Google, Facebook, custom

Google Shopping (XML)

Each product has: title, description, price (and sale price when there's a lower selling price), availability (in stock / out of stock), condition (always "new"), brand (the seller's name), image, GTIN and MPN (both filled with your SKU), Google product category and shipping weight. Prices are in your store's main currency.

Known problems: the product link and image link aren't full web addresses; GTIN is your SKU, not a real barcode; brand is the seller name (may be empty on a single-seller store).

Facebook (CSV)

Columns: id, title, description, availability, condition, price, link, image_link, brand. Same link and image problems as above.

Custom

Lets you pick XML, CSV or JSON, but today it produces the same file as Google (XML), Facebook (CSV) or a fixed JSON list — the columns you tick in Field Mapping are not used.

Variants

Only main products are included, not each size or colour separately.
