Resolving duplicate items

After reviewing the item details, you can decide whether the items are duplicates. You will need to provide a response to the duplication report.

1. Use the Bulk Item SetupAPI with the query parameterfeedTypeand EnumSPLIT_MERGE to confirm items are duplicates and have your offer merge to the catalog item.
2. POST a response with the Product ID and ProductIDType (i.e., GTIN) to the endpoint /dispute/duplicates/contest to claim the items are unique.
