I have created the Sell Application using Sell API. I have fetched the Orders List using Postman. But when I try to fetch the items using SKU its giving me 500 [Internal Server error] . & Also when i try to get inventory items using this API call [ https://api.ebay.com/sell/inventory/v1/inventory_item? ] for getting inventory. but for this API call this gives me 500 [ internal server error ].
why i am getting this error ? Is there anyother API to get active inventory ? or get inventory by sku . i also want to update quantity .
