Reddit catalog feed for Shopify

Catalog Manager reads a hosted file on the schedule you define: hourly, daily, or weekly at the time and day you pick. The URL can be HTTPS, FTP or SFTP, the file CSV, TSV, RSS 2.0 XML, a Google Sheet or a compressed archive up to 200 MB; only ATOM is ruled out. Feedflock renders the tab-delimited form Reddit's own documentation speaks in (columns, never elements) and hosts it on a stable public URL, regenerated every hour.

Choose the import mode deliberately: Replace imports and removes every product no longer in the file (usually what you want when Feedflock's product selection filters the catalog), while Update never deletes, so a filtered-out product keeps being advertised. And nobody tells you when a sync runs or fails: Reddit recommends checking your catalog regularly, which is exactly what Feedflock's fetch tracking does for you.

Reddit's required set is six fields: id, title, description, link, image_link and price. Availability, condition, brand, gtin and mpn are all merely recommended, and description is required outright, where Google only recommends it. A product missing a required field is an error; a bad value in an optional one is a warning and the product may still serve.

Two limits decide what a redditor actually reads: titles over 35 characters may be truncated in the product caption, and descriptions are recommended at 180 even though 5,000 fit. The image behind image_link must be a JPG or PNG of at least 500 × 500 px and at most 20 MB (no WebP, no GIF), and Reddit suggests a white background. The price is a number, a space and an ISO 4217 code, such as 59.00 USD, in the one currency the whole catalog shares.

Every attribute Reddit publishes is a Google Shopping attribute, and the category column is literally called google_product_category: a valid Google taxonomy ID or path. A Google TSV or RSS file will very likely load. But Reddit's required set is smaller than Google's, and where the vocabularies differ, Reddit's spelling wins: gender is Male, Female or Unisex capitalized, gtin allows an empty cell next to the usual lengths, and availability runs in_stock, out_of_stock, preorder, backorder.

The one multi-value field is packed, not repeated: additional_image_links is a single cell holding a JSON-encoded list of URLs. Feedflock builds it from your product gallery, skipping the main image. Alongside google_product_category the feed carries product_type, your own categorization. Reddit publishes no tree of its own, so both come from the mapping you already maintain for Google.

A catalog by itself runs no ads. Product Ads need a catalog, at least one product set (an All Products set is created for every catalog) and a campaign with the Catalog Sales objective. Dynamic Product Ads need more: the Reddit Pixel or Conversions API sending ViewContent, AddToCart and Purchase events, the catalog mapped to that pixel, and (the part that silently breaks) the product id in the feed matching the id the pixel sends.

Sold-out products belong in the file: availability is recommended, not required, and an unavailable value is a warning, not a rejection. Reddit's own remedy is a filter, not a deletion: a product set filtered on in_stock keeps sold-out items out of the ads while the rows stay ready for the restock.
