Find all Remote Event Receivers in a SharePoint Online site
Identify all your Remote Event Receivers in SharePoint Online before they are deprecated.
Dan ToftSummary
Remote Event Receivers (RERs) are a way to extend the functionality of SharePoint Online by allowing developers to execute custom code in response to specific events that occur within a SharePoint site. However, starting April 2. 2026, Microsoft is deprecating RERs in favor of more modern approaches like Power Automate and webhooks. This script helps administrators identify and manage existing RERs before the deprecation date.
This script will enumerate all Remote Event Receivers in all SharePoint Online site collections and display their properties, such as the event type, the endpoint URL, and the status.
$TenantUrl = "https://<tenant>.sharepoint.com/";
# I recommend using app-only authentication for this script
Connect-PnPOnline -Url $TenantUrl -ClientId "<client-id>" -Tenant "<tenant>.onmicrosoft.com" -CertificatePath "<path-to-certificate>" -CertificatePassword (ConvertTo-SecureString "<certificate-password>" -AsPlainText -Force);
$Sites = Get-PnPTenantSite;
$ReceiverInfo = @();
foreach ($Site in $Sites) {
Connect-PnPOnline -Url $Site.Url;

$Lists = Get-PnPList;
