How do I set the custom inventory when uploading from Shopify to eBay?

eBay limits the seller on the listing that can be listed and sold. You can easily view your seller limits by visiting your eBay seller hub. So for this case, you can either request eBay support to increase the limit or limit the inventory sent to eBay while uploading products from our app.
