Hello -- trying to get ebay current & historical data into client's site for referral revenue and getting "Insufficient permissions to fulfill the request." hitting /marketplace_insights/v1_beta/item_sales/
We're not storing data, just building small server to keep API key secret. ;)
Also need to know what the proper API key to store in backend? It looks like the Get OAuth Application Token keys generated in API Explorer expire?
thx!
