4 steps. The final node is the artifact you end up with.

What this does

Your product catalogue and your live channel feed get compared field by field: price, stock status, title, identifier, availability. Anything that disagrees is listed with the field and both values.

It catches the failures that are silent until they are expensive — the product that went out of stock in the store but stayed buyable in the feed, the price that was updated in one place and not the other, the identifier that broke and quietly dropped the item from the channel.

What you get

  • The workflow file with the adapter for your platform
  • The comparison rules, including the tolerance settings for fields where an exact match is the wrong test
  • A setup document covering credentials, the daily schedule and how to read the output
  • A note on the failure that costs the most: out-of-stock items still marked available, which generate orders you cannot fulfil and the cancellations that follow

Honest limits

It compares two systems. If a value is wrong in both, it will not notice — that needs a third reference, usually the supplier’s sheet, which is a variation worth building if you dropship.
