Remote Event Receivers are retiring: move to SharePoint webhooks before July 1, 2027
All SharePoint Online remote event receivers stop working on July 1, 2027; migrate to SharePoint webhooks.
“This extension is a bridge, not a destination.”
Microsoft announced that SharePoint Online Remote Event Receivers will be fully retired on July 1, 2027, following the Azure ACS retirement, and developers must migrate to SharePoint webhooks or Microsoft Graph change notifications. This is a developer platform deprecation notice with no meaningful AI industry signal.
