Árcédula feed for Shopify

Árcédula pulls your products from a feed URL you set in the partner portal under Termékek → Feedek, and one shop may register several feeds, so a split catalog is allowed. The spec says the feeds are re-read from time to time; the terms put a number on the visible part: prices on the site refresh nightly, with a delay it does not exclude.

Two conditions sit outside the feed itself. Registration is reviewed (Árcédula decides whether to accept it), and nothing is displayed without a positive prepaid balance: when it runs out, the products come down. And the file must keep answering: an unreachable data file is one of the four suspension triggers in the terms, alongside false or misleading data, malware and the empty balance. Feedflock hosts the file on a stable URL and regenerates it every hour, so both the freshness and the availability hold.

The whole vocabulary is thirteen fields, and the field table marks five of them Kötelező: identifier, manufacturer, name, url and price. The identifier is your own unique id for the offer and it does not have to be numeric; their examples run a plain number, a SKU-style code and a UUID. Unlike some of its neighbours, Árcédula does not ask you to keep the brand out of the name; its own examples ship “Apple iPhone 13 mini” beside a manufacturer of “Apple”.

The URL is where the click lands, and Árcédula's own tip is to add a tracking parameter to it (?from=arcedula) so you can tell its clicks apart in your analytics. Feedflock's default deep-links each variant with ?variant=, and you can add the source parameter in the same template.

The price is “the gross price of the product in forint”: a bare whole number, no currency suffix, and there is no VAT or net-price element in the format. The availability enum has exactly three camelCase values: inStock, orderable, outOfStock. The spec contradicts itself once here: the summary table's example column prints in_stock, but the status table and all three format tables say inStock, and that is what Feedflock sends, derived from your Shopify stock.

Delivery is two numbers per offer, both gross forints: deliveryPrice, where 0 explicitly means free delivery, and deliveryTimeInDays, a count of working days, not a phrase. Because a guessed value is a promise to every shopper, the template leaves both empty until you set a rate you actually charge.

Árcédula accepts JSON, XML and CSV with the same thirteen property names, each with a worked example on its one-page spec. The CSV form cannot carry specifications at all, which is why the template emits XML: a bare <products> root with one <product> per offer, values entity-escaped rather than CDATA-wrapped, exactly like the spec's own sample.

Two documented alternatives let you reuse what you already run. An Árukereső-format feed is accepted field for field, with one twist: it has no stock field, so Árcédula derives availability from the delivery time. A Google product feed is mapped too, but preorder and backorder are not compatible and are read as empty. The native feed remains the only one that carries specifications, the three-state availability and both delivery numbers.
