Recently I am not able to create (remote) event receivers in my SPO environment(s).

  • Create new site
  • Create new list
  • Add event receiver using PnP.PowerShell
Add-PnPEventReceiver -List "test" -Name test -Url "https://webhook.site/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -EventReceiverType ItemAdded -Synchronization DefaultSynchronization

Nothing is triggered on the Listener. Tested on different tenants and with different listeners (webhooke.site and Azure Function). Does anyone else facing this issue?


So, finally figured this one out. It seems like modern authetication is not supported when adding eventrecivers. So using legacy cookie based authentication when connecting using pnp (-UseWebLogin) and everything works fine.

I have not made a deep dive into the issue, so i can not tell if the issue is with PnP or SharePoint..
