When a product you sell is already on Amazon, you don't need to create a new listing. You can simply add your offer to the existing Amazon product. The app helps you find these matches with Amazon Lookup and Multi-Offer Listing.

What Amazon Lookup does

Amazon Lookup checks your products against Amazon's catalog using the product's barcode (UPC, EAN, or GTIN). If a matching product is found, the app:

• Saves the matching ASIN on your product.
• Changes the product status to Not Listed: Offer.

This means the product is ready to be uploaded as an Offer.

How to run Amazon Lookup

You can run it for your full catalog or for selected products.

For your full catalog

1. Open the Listings page in the app.
2. Click the three-dot (⋮) menu at the top right (next to the "Fetch Product Type" button).
3. Click Amazon Lookup.

For selected products

1. Open the Listings page in the app.
2. Tick the products you want to look up.
3. Click Select Actions at the top.
4. Choose Amazon Lookup.

What if barcode-based lookup doesn't find a match?

If Amazon Lookup can't find a match by barcode, you still have a fallback: Multi-Offer Listing. This searches Amazon by your product's title and shows you possible matches.

How to use Multi-Offer Listing

1. Open the Listings page.
2. Tick the products you want to match.
3. Click Select Actions.
4. Choose Multi Offer Listing.

5. A modal opens listing every Amazon ASIN that matches your product's title — with title, brand, and image.
6. Click Link on the ASIN you want to attach your offer to.

The app saves your choice and updates the product's ASIN.
