eBay API Error: Duplicate custom variation label

This eBay API error indicates some inconsistency of product data between the system that submits data (GeekSeller) and data about a product that already exists on eBay under a seller’s account.

Potential reasons for Duplicate custom variation label error:

  • a seller modified or republishes an item via eBay panel instead of making changes via GeekSeller panel. This results in conflicting information on both platforms and shows the error during submission.
  • It could also happen that a seller tries to republish a product that exists under a category of products which requirements were updated comparing to what eBay expected before.
    • For example, eBay requires now additional attributes to be added to the product, while it was not expected¬†when a product was published initially.

Solution: remove a product from the GeekSeller panel, and initiate import of all new products from eBay to GeekSeller. If you require any further help you can contact our support team here.
