Product catalog changes that propagate to every channel in real time
Per-attribute catalog updates that fire the moment something changes — your product detail pages, your ads, and every marketplace get the new state in seconds, not 36 hours.
The problem
You updated a regulated claim on a supplement SKU in Salsify last Tuesday. Google Shopping picked it up Wednesday night during the nightly sync. Meta Marketplace synced Thursday. Amazon synced Friday. Three customers ordered the old version on Wednesday morning because your product detail page regenerated descriptions before the change propagated. Your paid creative was still running ads with the old claim through Friday. Your Texas marketplace listings showed the wrong compliance language for 36 hours.
The PIM platforms (Salsify, Productsup, Akeneo, inriver, Syndigo) store your canonical product data and fire webhooks at the whole-record level — so a tiny attribute change triggers downstream systems to re-process the entire record. Feed management tools (Feedonomics, GoDataFeed, DataFeedWatch, Channable) pull from your PIM on a schedule, hourly at best. Marketplace syndication platforms (Mirakl, Rithum, Listrak) push updates in daily-to-hourly batches. Generic event-streaming tools (Kafka, EventBridge, Pub/Sub) deliver events but leave you to build the catalog awareness yourself. iPaaS (Zapier, Make, Workato) breaks at multi-channel scale.
The gap is per-attribute change events that know what kind of attribute changed (price, claim, image, compliance language, inventory) and which downstream channels care, with state-specific routing for regulated categories.
What success looks like
When any attribute on a product changes — a price, a regulated claim, an image, a variant spec, a state-specific descriptor — the system fires a typed event keyed to exactly what changed.
The right downstream channels subscribe to the attribute types they care about. Google Shopping, Meta Marketplace, Amazon, Walmart, retailer feeds, your product detail page generator, your paid creative system, your social posting, your Google Business Profile product surface, and your email broadcast all read from the same stream. Price changes route to the repricer and ads. Compliance claim changes pause ads and trigger a regeneration of the product detail page. Inventory changes sync to marketplace availability.
State-specific descriptors ( dosage variants for Massachusetts, Prop 65 warnings for California) emit only to the subscribers in the right jurisdictions. Every emission ties to the product's history for regulator inquiry response (FDA structure-function, FTC claim substantiation restrictions).
Feedonomics, GoDataFeed, DataFeedWatch, and Channable keep working as downstream channels by consuming from the canonical stream rather than running their own batch sync.
How most operators solve this today
A few categories of tools touch this problem, but none of them fire typed per-attribute events to the right downstream channels in real time:
PIM platforms (Salsify, Productsup, Akeneo, inriver, Syndigo)
$20,000 to $300,000+/year
Store the canonical product data with whole-record webhooks. A price change triggers downstream systems to re-process the entire record.
Product feed management (Feedonomics, GoDataFeed, DataFeedWatch, Channable)
$39 to $5,000+/month
Optimize feeds for Google Shopping, Meta, Bing, retailer feeds. Pull from your PIM on a schedule (hourly at best). Not event-driven.
Marketplace and retailer syndication (Mirakl, Rithum / ChannelAdvisor, Listrak)
$25,000 to $200,000+/year
Push catalog updates in daily-to-hourly batches. Not per-attribute event-driven.
Generic event-streaming infrastructure (Kafka, EventBridge, Pub/Sub, Inngest, Svix, Hookdeck)
$1 to $30,000+/month
Generic event delivery. You build the per-channel subscription logic and catalog awareness yourself.
iPaaS automation (Zapier, Make, Workato, Tray.io)
$20 to $5,000/month
Point-to-point. Breaks at multi-channel scale and has no catalog-schema awareness.
Build it in-house
Data engineer ($130-180k) + ongoing API drift maintenance
Still runs on nightly batch in most attempts. API drift across 5+ marketplaces eats about a third of an engineer's time.
What changes when this is an agent skill
The system fires per-attribute typed events the moment any catalog attribute changes — price, inventory state, regulated claim, product description, image, variant attribute, state-specific descriptor, channel-specific descriptor, marketplace-specific compliance language.
Each downstream channel subscribes to the attribute types it cares about. Google Shopping, Meta Marketplace, Amazon, Walmart, retailer feeds, your product detail page, your paid creative, your social posting, your Google Business Profile, and your email broadcasts all read from the same stream. A price change routes to your repricer and your ads. A compliance change pauses the ad and regenerates the product detail page. An inventory change syncs to marketplace availability.
State-specific descriptors ( dosage for Massachusetts, Prop 65 for California) emit only to the subscribers in the right jurisdictions. Every emission ties to the product's history for regulator inquiry response.
Feedonomics, GoDataFeed, DataFeedWatch, and Channable keep working as downstream channels by consuming from the canonical stream. Your PIM (Salsify, Productsup, Akeneo) stays upstream as the source of record.

FAQ
- What does this actually do?
- When any attribute on a product changes — a price, a claim, an image, a state-specific descriptor — it fires a typed event the moment it happens. Each downstream channel (Google Shopping, Meta, Amazon, your product detail page, your ads) subscribes to the attribute types it cares about and consumes the change in real time.
- How is this different from Salsify or Productsup?
- PIM platforms store your canonical product data and fire whole-record webhooks. A tiny attribute change triggers downstream systems to re-process the entire record. This emits per-attribute typed events with state-specific routing and per-channel subscriptions.
- How is this different from Feedonomics or GoDataFeed?
- Feed management tools pull from your PIM on a schedule. This pushes per-attribute events to them (and every other downstream subscriber) in real time. Feedonomics becomes a subscriber rather than a scheduled puller.
- How is this different from Mirakl or Rithum?
- Marketplace syndication platforms push catalog updates in batches. This emits per-attribute events; marketplace subscribers consume them as a real-time stream.
- What attribute types does it emit events for?
- Price, inventory state, regulated claim, product description, image, variant attribute, state-specific descriptor, channel-specific descriptor, marketplace-specific compliance language, and any custom attribute class you define.
- How does this work alongside catalog ingest and conflict resolution?
- Multi-source catalog ingest brings data in from your POS, ERP, PIM, and supplier feeds. Conflict resolution decides which source wins for each attribute. This emits the resolved value as a typed change event downstream.
- How does this handle compliance changes specifically?
- Compliance changes (FDA structure-function language, FTC claim substantiation restrictions) fire as compliance-aware events. Downstream systems can pause ads, regenerate product pages, or reroute based on the change.
