HI, new to ebay development trying to code addon for my friend who is a seller, the app should get pending (unfulfilled orders) and print packing slips, postage labels etc.
Created seller and buyer accounts in sandbox, used TradingAPI addItem to list some items. My understanding i need to browse searching for those items (under buyer oauth token) to get itemIds (which are not the itemIds returned from TradingAPI) then use application token to initiateGuestCheckoutSession (or buyer aoauth token to initiateCheckoutSession) but i cant even find the items I added as seller.
Any attempts to intiateCheckoutSessions failed assuming the itemId is incorrect.
Wish there would be a guide showing end-to-end (ideally with curl commands) creating item, buying item which should create the order pending fulfillment etc).
Can anyone point me please into right direction??
