1. Open a previously created plugin solution in Visual Studio.
2. Add the following private variable:

private Guid serviceEndpointId; 

3. Ensure that the public constructor of your class accepts a string parameter called config and add the following code to you constructor:

if (string.IsNullOrEmpty(config) || !Guid.TryParse(config, out serviceEndpointId)) 
{ 
    throw new InvalidPluginExecutionException("Service endpoint ID should be passed as config."); 
} 

4. In your Execute method add the following code:

var cloudService = (IServiceEndpointNotificationService)serviceProvider.GetService(typeof(IServiceEndpointNotificationService)); 
if (cloudService == null) 
    throw new InvalidPluginExecutionException("Failed to retrieve the service bus service."); 
string response = cloudService.Execute(new EntityReference("serviceendpoint", serviceEndpointId), context); 

5. Compile your code and register the assembly in your Dynamics 365 instance.
6. Using the Plug-in Registration Tool add a post-update step to your plugin with the following details:
   • Message: Update
   • Primary Entity: account
   • Filtering Attributes: Account Name
   • Execution Mode: Synchronous
   • Unsecure Configuration: <Your endpoint GUID>
   • Click on Update Step
