If you can get an api from ebay that allows you to grab products to use then you can just use Wix Fetch or Wix HTTP Functions to get your products.

Otherwise, you can try to download your products as a csv file and import them into your Wix Stores.

However, if you can’t do that then you will need to manually get them all into your datasets.
