If you want to test webhooks locally you probably use Ngrok or Localtunnel. I do.
Recently I wanted to play with Instagram webhooks and I couldn’t because surprisingly
Facebook do not accept Ngrok and Localtunnel URLs anymore and marks them as
malicious and/or abusive.
I don’t really understand why Facebook blocked the only known solutions of local webhooks testing.
Fortunately I have a server and a domain name.
What we’ll need:
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.
