Write plug-ins to extend business processes
Applies to Dynamics 365 (online), version 9.x
A plug-in is custom business logic that you can integrate with Dynamics 365 (online) Customer Engagement to modify or augment the standard behavior of the platform. Plug-ins are event handlers since they are registered to execute in response to a particular event being fired by the platform.
The following topics describe how to add custom business logic to Dynamics 365 through the development and registration of plug-ins. For more information about the run-time execution of plug-ins and the plug-in development framework, see Introduction to the Event Framework.
