Product feed management that fixes the data first.

A product feed manager is the tool, or the person, responsible for turning a catalog into the files each sales channel expects — Google Shopping, Meta, Pinterest, TikTok, Bing, marketplaces — keeping those files current, and dealing with whatever the channel rejects. Standalone feed managers take product data as given and reshape it per channel. Apimio is a product feed manager built into the catalog itself (Advanced and Enterprise plans): it fixes the data, maps categories to Google's taxonomy, predicts rejections before publish, hosts each feed at a URL that refreshes on schedule, and pulls the real rejections back from the channel so you can see prediction and outcome together.

Product feed management software generates channel-specific product files from your catalog, hosts or submits them, refreshes them on a schedule and reports what the channel accepted or rejected. Standalone products like Feedonomics, DataFeedWatch, Channable and GoDataFeed do this as a separate subscription on top of whatever holds your product data. Apimio includes product feed management inside the catalog platform (Advanced and Enterprise plans), so the same system that scores and fixes product data also builds the feeds — one subscription rather than two, and no gap between the data and the file.

As often as your prices, stock or content change, and at least once a day. Google Merchant Center can fetch a hosted feed on a daily schedule and Meta Commerce Manager can poll hourly, so a feed that is refreshed less often than your price changes will carry stale numbers and eventually trigger price-mismatch disapprovals. In Apimio each hosted feed has its own refresh cadence (Advanced and Enterprise plans), so you can refresh a fast-moving sale feed hourly and a stable catalog feed daily, and a stale-feed badge flags any feed that missed its schedule.

Because the product data does not meet a rule, not because the XML is malformed. The usual causes are a missing or invalid GTIN, a title over the character limit, an availability value that is not one of Google's accepted terms, an image below minimum dimensions, a price or currency in the feed that does not match the landing page, or a required field that is empty for that product type. Apimio's pre-publish diagnostics check exactly those families before the feed goes live and list every affected product with a link to fix it, and once you connect Merchant Center the real rejection status is pulled back next to the prediction so nothing gets missed.

Shopify's Google & YouTube sales channel can sync products to Merchant Center, and for a single store with simple products it is often enough. It does not tell you in advance which products will be rejected, it does not map your categories for other channels, and it does not carry Meta, Pinterest, TikTok or Bing from the same setup. Merchants running several stores, large variant matrices, or several channels usually add a feed tool. Apimio covers that case from the catalog (Advanced and Enterprise plans): one record, five channel templates, diagnostics before publish and real rejections pulled back afterwards.

For Google Shopping, Meta, Pinterest, TikTok and Bing, no — Apimio generates and hosts those feeds itself (Advanced and Enterprise plans), and produces Amazon and Walmart as importable TSV files. Where a dedicated feed app may still earn its place: you need a channel Apimio has no template for, you want live API submission to a marketplace rather than a file, or you run rule-heavy title rewriting per channel at a scale Feedonomics or Channable specialize in. We spell out the trade-off honestly at /compare/feedonomics. If data quality is part of your disapproval problem, one subscription that fixes and feeds beats two that do half each.

Advanced PIM at $399 a month and Enterprise PIM from $999 a month. Product Feeds are not part of Basic PIM at $199 a month, which covers a single store, 10,000 SKUs, Quality Guard, Bulk Edit, Line Sheets and the AI content assists. Advanced adds multi-store, 50,000 SKUs, Product Feeds, Scheduled Imports, Sale Scheduler, the Image Library, multi-language and the API. Apimio offers a 14-day free trial, and if a subscription lapses your feeds pause rather than delete — turn it back on and they resume. Full detail is at /pricing.

Two ways, and it matters to keep them apart. The feed itself is a hosted URL that Merchant Center or Commerce Manager fetches on its own schedule — that is not a live API sync, and Apimio does not claim one. Separately, you can connect your Merchant Center or Commerce Manager account so Apimio pulls each item's actual rejection status back onto the product and shows it next to the predicted issues (Advanced and Enterprise plans). Retrieval is time-boxed per item and only runs once you have connected the account.

Yes, if it reads one product record and writes several templates. In Apimio the Google Shopping XML, Meta, Pinterest, TikTok and Bing feeds are templates on the same engine (Advanced and Enterprise plans), each with its own product selection and refresh cadence, up to 25 feeds per organization. Because they share one record and one category map, a title fix or a price change lands in every channel at the next refresh, and two channels can never show two prices for the same SKU. Shopify remains the only channel Apimio syncs with live and two-way.

A capped set of the rules that cause most rejections, not the whole channel specification: required fields for that channel and product type, title length, availability values against the accepted vocabulary, image minimum dimensions, price and currency consistency, and GTIN presence. Each finding is a clickable row that opens the product so you fix it in the catalog, and a stale-feed badge shows when a feed has not refreshed on schedule. Apimio then pulls the channel's real verdict back after processing (Advanced and Enterprise plans), so the rules the check does not cover still show up — attached to the product, not buried in a diagnostics export.

Only if the feed is shaped for it. Channel feeds are full of channel-specific fields and abbreviated values that an LLM reads poorly. Apimio's agent-ready feed format is a template on the same engine (Advanced and Enterprise plans) that outputs complete attributes, resolved categories and plain-language descriptions, served as a hosted URL — the catalog an AI shopping assistant can actually read. It can be mapped to what the ChatGPT and OpenAI product-feed programs ask for; it is not an official OpenAI specification. Details are at /chatgpt-product-feed.
