Ceno.lv feed for Shopify

Ceno reads a file from a URL. Its spec page shows where the file should live with two example addresses, says the file must be saved in UTF-8 to work, and states that Ceno updates its database of product ranges and shop information every day. For that reason it recommends that shops refresh availability and assortment daily as well.

Feedflock hosts the file on a stable URL and regenerates it as often as every hour, comfortably inside that daily rhythm. You hand Ceno the URL once, and there is nothing to upload again. If you already have a differently shaped XML, Ceno says other formats are supported too, but it wants to hear about it by e-mail after you register.

Ceno's XML page is one complete sample feed followed by the same elements again, each with a short comment. That is the whole vocabulary: thirteen product elements and ten delivery elements under <root>/<item>. There is no developer portal, no schema file and no validator to test against.

The page almost never says "mandatory". It demands prices in euros with VAT, the joining rules demand fitting images, and used is mandatory for second-hand goods; delivery elements and in_stock are only recommended. The template treats name, link, price and image as required, because an offer without them is not an offer, and leaves the rest optional.

All prices are given in euros with VAT, as a number whose decimal part is separated by a point. Ceno pairs price with price_sale: the normal price and the promotional one. Shopify models it the other way round (the price is what the customer pays today and the compare-at price is the old one), so the template gives price_sale no automatic value. If you want Ceno's pairing, you map the two fields yourself.

in_stock is more specific than a stock level: Ceno recommends giving the quantity in the warehouse that is available for delivery in Riga within four working days. The template sends Shopify's inventory count, never below 0. If your stock cannot reach Riga in that time, override the mapping with a number that is true for you.

Ceno has no delivery block and no carrier codes. Each method is an element of its own, so a DPD pickup price goes into delivery_dpd_paku_bode and nowhere else. Next to the six methods sit delivery_cost_riga and delivery_latvija, the maximum delivery prices for Riga and for Latvia, and delivery_days_riga and delivery_days_latvija, the maximum number of working days.

All ten are desirable, numeric, and have no default in the template. Ceno's rule is that an unsupported method is left empty, and a 0 would advertise free delivery, so Feedflock writes a delivery element only once you have entered your own value. Take care when you also list on Salidzini.lv: the same element names mean the maximum on Ceno and the cheapest there.

Registration at ceno.lv/register/store comes with nine rules of use. Some are about the feed, and the template covers them: the XML follows Ceno's sample, each variant is its own item with its own link, and image is always filled when the product has one. Others are about the shop: true registration data, one shop per domain, and products a customer can actually buy and receive in Latvia.

Two need action on your side. Ceno expects its banner on the registered shop's website, preferably on the home page or in the footer, which is a small theme edit. And it forbids fake profiles used to review your own shop or to discredit competitors; a shop suspected of unfair behaviour can be warned or blocked.
