However, I got confused by checking the steps mentioned in this article because ebay website seem to have a completely different flow of applying this token.
Copy “Verification token” to fill in “Verification token” on eaby
Copy “Url notification” to fill in “Marketplace account deletion notification endpoint” on ebay. (and replace some string attached following the suggestion)
@Cheng-En You have to open the xentral eBay Importer once and then save it. Unfortunately, only then will the token and the URL be saved in the database. Try this again. Without getting the verification from eBay, you are stuck at this point.
