Hi All,
I am trying to subscribe a sharepoint list/library to a webhook (created using function apps). I am trying to do this by using SP-editor chrome extension by following the article "https://ypcode.wordpress.com/2017/09/18/easy-ways-to-subscribe-a-sharepoint-list-webhook/". Two days before it was working and i was able to subscribe to a sharepoint list as well without any issues, however suddenly from yesterday i am getting error as "Failed to validate the notification url 'https://mywebhook.azurewebsites.net/api/myfunctionname". I even tried subscribing webhooks using pnp powershell as given in the article "https://ypcode.wordpress.com/2017/09/18/easy-ways-to-subscribe-a-sharepoint-list-webhook/", but over there as well i am getting the same error.
Please let me know if any one has some solution for this error "Failed to validate the notification url ".
Regards,
Subhash
