Controlling Gallery settings with ExternalProductID and ProductListingDetails

Summary

When listing an item using the eBay Catalog feature, special logic exists for the determination of the PictureDetails.GalleryURL setting. The behavior of AddItem and which image is used for Gallery, varies based on the use of the ExternalProductID input, versus the ProductListingDetails container, and the explicit GalleryType setting. The examples below explain the behavior through examples of various combinations of settings.

ExternalProductID

When listing with ExternalProductID, the following logic applies:

• GalleryType = Gallery
  • IncludeStockPhotoURL defaults to True
  • UseStockPhotoURLasGallery defaults to True
  • GalleryURL is StockPhotoURL
• GalleryType = Gallery AND GalleryURL specified
• • IncludeStockPhotoURL defaults to True
  • UseStockPhotoURLasGallery set to False
  • GalleryURL is user input defined GalleryURL
• GalleryType = None
  • IncludeStockPhotoURL defaults to True
  • No Gallery
