Ebay API and Platform Notifications
November 2, 2018
If your web site isn’t receiving the notifications from Ebay even though you have everything configured AND you’re using oAuth tokens for
SetNotificationsPreferences request then you have nothing to do except contact the Ebay support.
Currently they have a special whitelist where they have to add your
APP ID and the only way to add your app to that whitelist is to contact them.
You can actually try to post a thread on their forum, but in this case you have to wait while someone form ebay staff will notice it.
Unfortunately the Support costs money and the price is $75/hour. Good news is they are not billing you for the request to whitelist your app so you can spend that hour for something else.
