Error message

[Duplicate Offer] Duplicate found: retailer offer '86089d36-c13b-4758-ae90-1d67203abf9c' already has EAN 8432393136424 and condition NEW.

What does this error mean?

The marketplace rejected your offer because an active offer with the exact same EAN and product condition (e.g., "NEW") already exists in your Bol.com seller account. Bol.com does not allow a single seller to have multiple identical offers.

How to solve this error

• Step 1: Review your Lengow product catalog to ensure there are no duplicate EANs being sent in your feed. If duplicates exist, fix your source data or use an Exclusion in Lengow to keep only one version of the product.
• Step 2: Log into your Bol.com seller back-office and manually delete the unwanted duplicate offers.
• Step 3: Perform a manual offer push in Lengow to resynchronize your feed and send the cleaned data to the marketplace.
