 	.PARAMETER Raw
 		Do not process the response object and instead return the raw result returned by the API.
+
+	.PARAMETER DeltaSession
+		A hashtable including delta sessions.
+		Use together with the delta endpoints, e.g. for the Graph API's user delta endpoint:
+		https://learn.microsoft.com/en-us/graph/api/user-delta
+		Provide an empty hashtable on the first request, the delta token data will be inserted into it.
+		Provide the same token for subsequent delta requests.
+
+		This allows retrieving changes over time, without having to reload the entire dataset.
+
+	.PARAMETER MinimalDelta
+		When receiving delta data, only return the changed properties (plus a unique identifier), rather than the full object.
+		Only used together with DeltaSession
 
 	.EXAMPLE
 		PS C:\> Invoke-EntraRequest -Path 'alerts' -RequiredScopes 'Alert.Read'
 
 		Return a list of defender alerts.
+
+	.EXAMPLE
+		PS C:\> Invoke-EntraRequest -Path 'users/delta' -DeltaSession $delta
+
+		Retrieves all users on first request.
+		Subsequent calls will only return users that have been changed in the meantime.
