How does Whatnot crosslisting work?
Turn your catalog into Whatnot Buy It Now listings without copy-pasting. ResaleOS publishes to Whatnot through Seller Hub automation and keeps stock in lockstep with the rest of your channels.
ResaleOS publishes to Whatnot through a secure, signed-in browser session — no public API required. You build each product once in ResaleOS, publish it to Whatnot and every other channel from one catalog, and inventory stays in sync so a sale anywhere ends the listing everywhere.
How Whatnot crosslisting works, step by step
Add your product once in ResaleOS
Create the product in your ResaleOS catalog — photos, price, condition, and details. This is the single source of truth for every channel.
Choose Whatnot (and any other channels)
Select Whatnot as a destination. AI adapts the listing to Whatnot's title limits, category tree, and required fields automatically.
Publish
Hit publish and ResaleOS creates the listing through a secure browser session. Edit once in ResaleOS and changes push everywhere.
Sell once, delist everywhere
When the item sells on Whatnot or any other channel, ResaleOS records the sale, decrements stock, and ends the listing everywhere else — so you never oversell.
