What is the best way to get completed listings data from the eBay API? From what I've read it should be the Marketplace Insights API, but after applying to eBay for access to this they said:
Unfortunately, we no longer provide access to Marketplace Insights API to our partners. We apologize for any inconvenience caused.
I am now stuck as the application I am developing needs a way to get sold listing data or it won't be successful. Can anyone help advise me on what to do?
