Unfortunately if you add Item Specifics in My eBay to products listed by our system, the item specifics will get removed in the next product feed refresh.

You can add the necessary attribute data for Item Specifics in your eCommerce Store and we will feed them to eBay.

See the relevant articles below based on your eCommerce Platform.

You can also add Attribute Data directly into Omnivore, click here to follow the guide.
