Inject your own activity type service

Current version: 9.1

You can use your own service in the context of an activity type. You must register custom services  in configuration and inject them in the activity type constructor. 

Create a service and add it to the activity type constructor

  1. Create an interface and a concrete implementation for your service. The following example uses an IExampleService interface and an ExampleService concrete class:

    using System;
    namespace Documentation.Examples
        public interface IExampleService
            void DoSomething();
        public class ExampleService() : IExampleService
            public void DoSomething()
                // Does something
  2. Add the service interface to the constructor of your activity type and set a private service property as shown:

    using Sitecore.Xdb.MarketingAutomation.Core.Activity;
    using Sitecore.Xdb.MarketingAutomation.Core.Processing.Plan;
    using Microsoft.Extensions.Logging;
    namespace Documentation.Examples
        public class DoNothingActivity : IActivity
            private IExampleService ExampleService { get; set; }
            public IActivityServices Services { get; set; }
            public DoNothingActivity(IExampleService exampleService)
                ExampleService = exampleService;
            public ActivityResult Invoke(IContactProcessingContext context)
                return new SuccessMove();

Add the service to the configuration

  1. Navigate to the following folder in the Automation Engine root: \App_Data\Config\sitecore\MarketingAutomation


    In a local instance, the Automation Engine is located in the C:\path\to\xconnect\App_data\jobs\continuous\AutomationEngine folder.

  2. Create a new XML file that extends sc.MarketingAutomation.ActivityServices.xml and registers your custom services:

        Marketing Automation Activity Services configuration
                    <Type>Documentation.Examples.ExampleService, Documentation.Examples</Type>
                    <As>Documentation.Examples.IExampleService, Documentation.Examples</As>

    Node names must be unique - for example, there can only be one Documentation.ExampleService node. The node name is up to you - it does not need to be the full namespace of the service.
