Kelkoo feed for Shopify

Kelkoo's format is a plain UTF-8 XML file: a <products> root, one <product> per offer, every value as a child element, free text in CDATA. A delimited TXT with a header row of attribute names works too, but XML is what the template renders. There is no published item or file-size cap.

You do not upload the file. Kelkoo fetches it. You host the feed at a URL that must keep the same name over time, and Kelkoo pulls it on a published timetable that runs from 3 fetches a day (Belgium) through 4 (Czechia, the UK, Germany's neighbours) to 14 (France). Feedflock hosts the file on a stable URL and regenerates it every hour, so every fetch reads current prices and stock.

Ten attributes are unconditionally required: a stable id, the title, a description, both URLs, the main image, the price, availability, your category path and the delivery cost. A missing required attribute may keep that particular product from showing up, and Kelkoo has no merchant-facing diagnostics page to tell you, which is why the template warns instead.

The title is capped at 150 characters, must be plain text without promotional phrases or all-caps, must match the landing page, and every variant needs a distinguishing feature such as colour or size. Kelkoo's own example is “Adidas Retrorunner Sneakers - Blue - UK 7”. The description is required too: up to 3,000 characters about the product only, stripped of HTML. The price is a bare number without the currency, and it must exclude delivery costs, voucher-code reductions and any ecotax, which has its own field.

Kelkoo is one of the few channels that asks for two product URLs, and they are not interchangeable. product_url is the link the offer points to: it must start with https and it may be a tracking URL that redirects. Kelkoo explicitly recommends UTM parameters so you can attribute the traffic. landing_page_url must be the final URL the user sees, on your own domain, with no tracking solution and no URL parameter whatsoever.

The consequence is tidy: the ?variant= deep link that preselects the right size belongs on product_url, while landing_page_url stays the clean product address every variant shares. Feedflock's template maps both by default: the variant deep link on the first, the plain product URL on the second.

Kelkoo publishes no category tree at all. merchant_category carries your own full category path (“Men > Men's Shoes > Casual Shoes”, not just “Shoes”), and Kelkoo maps it to its taxonomy internally, which for a new merchant can take a few days. An optional second track, google_product_category, exists for a Google taxonomy path or id.

Availability is Kelkoo's numeric enum: 1 = In stock, 2 = Stock on order, 3 = Unknown, 4 = Pre-order, 5 = Available on order, 6 = Not in stock. Text is accepted but the numbers are preferred, and an out-of-stock item stays in the feed as 6. Delivery is two flat fields: delivery_cost, which is required, covers home delivery only and takes 0 for free, and delivery_time as free text. There is no carrier vocabulary, no COD element and no free-above threshold: weight-based rules are something you agree with your account manager, not something the feed can express.
