Issue description

I am not able to add a webhook subscription with an Azure logic app for "notificationUrl". It didn't work. I tweaked the logic app to return http status 200 instead of 202 and the token in the body to Sharepoint. it still didn't work. Does Sharepoint webhook supports Azure logic app? I am sure the MS Sharepoint team must test its own products first to see if they work nicely.
