How to integrate ButterCMS into your ASP.NET application

Just follow the simple steps below to complete the integration and begin creating pages with Butter. Be sure to check out our full guide to creating pages using the ButterCMS ASP.NET API.

First you would set up a new Customer Case Study page type in Butter and create a page. With your page defined, the ButterCMS API will return it in JSON format like this:

    "data": {
        "slug": "acme-co",
        "fields": {
            "facebook_open_graph_title": "Acme Co loves ButterCMS",
            "seo_title": "Acme Co Customer Case Study",
            "headline": "Acme Co saved 200% on Anvil costs with ButterCMS",
            "testimonial": "<p>We've been able to make anvils faster than ever before! - <em>Chief Anvil Maker</em></p>\r\n<p><img src=\"\" alt=\"\" caption=\"false\" width=\"249\" height=\"249\" /></p>",
            "customer_logo": "",

Display results in Views/CaseStudy.cshtml:

    <meta property="og:title" content="@ViewBag.FacebookTitle" /> 
    <img width="100%" src="@ViewBag.CustomerLogo">
</html> return render(request, 'case_study.html', {'case_study': })

To create these pages in our app, we create a route that fetches content for the page by using a URL slug parameter. This is how the Controllers/CaseStudyController.cs file might look:

using System.Threading.Tasks;
using System.Web.Mvc;
using ButterCMS;
using Newtonsoft.Json;

namespace ButterCmsExample.Controllers 
    public class CaseStudyController : Controller
        private ButterCMSClient Client;

        private static string _apiToken = "";

        public CaseStudyController()
            Client = new ButterCMSClient(_apiToken);

        public async Task<ActionResult> ShowCaseStudy(string slug)
            var json = await Client.ListPageAsync("customer_case_study", slug)
            dynamic page = ((dynamic)JsonConvert.DeserializeObject(json)).data.fields;
            ViewBag.SeoTitle = page.seo_title;
            ViewBag.FacebookTitle = page.facebook_open_graph_title;
            ViewBag.Headline = page.headline;
            ViewBag.CustomerLogo = page.customer_logo;
            ViewBag.Testimonial = page.testimonial;
            return View("Location");

That's it! If you browse to your homepage you'll see your homepage populated with the content you created in Butter.
