Remote event receivers in SharePoint 2013

The remote events supports

Site - Create, Move, Delete
List - Create, Delete
List schema - Create, Update, Delete
List Item - Create, Update, Delete, Move, CheckIn, UnCheckIn, CheckOut, AttachmentsAdded, AttachemntsRemoved, FileMoved, FileConverted
App - Install, Update, Uninstall

Some Impotent Points to be noted:

• Remote event receivers call across the networks
• After events use WCF(Windows communication foundation) call on remote web so that they do not block the sharepoint host nor delay the response back to the user
• Remote event recievers will only workf if the concern list is present in App Web
• SharePoint hosted apps doesnt support remote event receievers, its only provider hosted apps
• IRemoteEventService an interface thats get inherited in remote event recievers
• We have only two events called "ProcessEvent" which is a two way event and "ProcessOneWayEvent" for one way
• Properties argument defines the event that has fired on a list item
• We will be having only single entry point for all the events
• Properties.ItemEventProperties is for an item events and Properties.ListEventProperties for list events
• SPRemoteEventResult which is used to sent status back to SharePoint(used for sending information and also for canceling the events)

Before events example

After events example

• App Life Cycle events are two way events
• "ProcessOneWayEvent" never file in App related events

This are just brief points about remote event recievers.
