Paste the shop address. Nothing to export, nothing to install.
Fourthwall is where creators run their merch: hoodies, hats, posters, digital downloads. Ducted reads the catalog from the shop address alone - your own domain or a fourthwall.com one - so the products are ready to map before you have opened a spreadsheet.
The catalog arrives as structured records, not page text. Every item carries the fields a shopping feed actually needs.
Every size and colour arrives as its own record, grouped under its product - the shape Google Shopping and Meta ask for with apparel. A hoodie in six sizes and three colours is eighteen records that each advertise correctly, rather than one record that cannot.
The fields arrive pre-marked, so a new project maps itself: create a Google Shopping or Meta catalog feed and id, title, description, link, image, price, availability, brand, colour and size are filled in before you touch anything.
Sale prices and compare-at pricing come from a second Fourthwall data set, on every plan, applied per variant so a larger size priced above the compare-at price is never marked as on sale.
Ducted re-reads the shop on every scheduled refresh, so new drops appear and sold-out sizes switch to out of stock without anyone touching the feed. The shape of the data is checked on every refresh as well: if Fourthwall changes what it publishes, Ducted tells you rather than quietly serving an empty feed.
One mapped catalog, one output feed per channel. Each template carries that platform's required fields, accepted values and format rules.
