Returning an HTML Page from a Creatio Configuration Service

A Creatio configuration service is a WCF service that is typically used to create web services that consume and provide JSON. However, it is possible to also change the content type of the data returned to other types. This article will look at creating a configuration service that returns a HTML page that can be viewed like any HTML page.

We’ll create a service with an exposed GET method. We’ll set the content type to text/html and then create some HTML as a string which will be returned as a stream. Let’s look at the code for the service:

namespace Terrasoft.Configuration
    using System;
    using System.Web;
    using System.ServiceModel;
    using System.ServiceModel.Web;
    using System.ServiceModel.Activation;
    using System.IO;
    using System.Text;
    using Terrasoft.Core;
    using Terrasoft.Web.Common;
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    public class UsrTestService : BaseService
        [WebInvoke(Method = "GET")]
        public Stream GetHtmlPage()
            WebOperationContext.Current.OutgoingResponse.ContentType = "text/html";
            var page = @"
                    <head><title>Test HTML Page</title><head>
                        <p>This is a test HTML page returned from Creatio</p>
            var stream = new MemoryStream(Encoding.UTF8.GetBytes(page));
            return stream;

The end result is that we can navigate to the web service in our browser using the URL:


And we’ll see the following page:

Note, you can also create this as an anonymous web service so it can be called outside of Creatio as well.
