.NET library for the Contentful Content Delivery API, Content Preview API and the Contentful Management API. It helps you to easily access your Content stored in Contentful with your .NET applications.

What is Contentful?

Contentful provides content infrastructure for digital teams to power websites, apps, and devices. Unlike a CMS, Contentful was built to integrate with the modern software stack. It offers a central hub for structured content, powerful management and delivery APIs, and a customizable web app that enable developers and content creators to ship their products faster.

Core Features

Getting started

We recommend you use the NuGet Package Manager to add the library to your .NET Application using one of the following options:

  • In Visual Studio, open Package Manager Console window and run the following command:

    PM> Install-Package contentful.csharp
  • In a command-line, run the following .NET CLI command:

    > dotnet add package contentful.csharp


The ContentfulClient handles all communication with the Contentful Content Delivery API.

To create a new client you need to pass an HttpClient, your delivery API key and any other configuration options:

var httpClient = new HttpClient();
var client = new ContentfulClient(httpClient, "<content_delivery_api_key>", "<content_preview_api_key>", "<space_id>");


var httpClient = new HttpClient();
var options = new ContentfulOptions
    DeliveryApiKey = "<content_delivery_api_key>",
    PreviewApiKey = "<content_preview_api_key>",
    SpaceId = "<space_id>"
var client = new ContentfulClient(httpClient, options);

If you are running core and wish to take advantage of the options pattern you can do so by passing an IOptions<ContentfulOptions> to the constructor. This lets you keep your authorization token in your application settings, in environment variables or your own custom Microsoft.Extensions.Configuration.IConfigurationSource provider.

Your first request

After creating a ContentfulClient, you can now query for a single entry:

var entry = await client.GetEntry<Product>("<entry_id>");

Console.WriteLine(entry.ProductName); // => Contentful
Console.WriteLine(entry.Price); // => 12.38
Console.WriteLine(entry.Description); // => A fantastic product.
public class Product
    public string ProductName { get; set; }
    public string Price { get; set; }
    public string Description { get; set; }

The properties of your class will be automatically deserialized from fields with matching names.

If you're interested in the system properties of the entry, add a SystemProperties property to the class.

public class Product
    public SystemProperties Sys { get; set; }
    public string ProductName { get; set; }
    public string Price { get; set; }
    public string Description { get; set; }
var productEntry = await client.GetEntry<Product>("<entry_id>");

Console.WriteLine(productEntry.Price); // => 12.38
Console.WriteLine(productEntry.Sys.Id); // => 2CfTFQGwogugS6QcOuwO6q

Management API

To edit, update and delete content you use the ContentfulManagementClient class which uses the same familiar pattern as the regular client.

var httpClient = new HttpClient();
var managementClient = new ContentfulManagementClient(httpClient, "<content_management_api_key>", "<space_id>");

You can then use the client to, for example, create a content type.

var contentType = new ContentType();
contentType.SystemProperties = new SystemProperties()
    Id = "new-content-type"
contentType.Name = "New contenttype";
contentType.Fields = new List<Field>()
    new Field()
        Name = "Field1",
        Id = "field1",
        Type = "Text"
    new Field()
        Name = "Field2",
        Id = "field2",
        Type = "Integer"

await managementClient.CreateOrUpdateContentType(contentType);

Using the library with the Preview API

This library can also be used with the Preview API. Make sure you have a preview API key configured and set UsePreviewAPI on your client.

var httpClient = new HttpClient();
var options = new ContentfulOptions()
    DeliveryApiKey = "<content_delivery_api_key>",
    PreviewApiKey, "<content_preview_api_key>"
    SpaceId = "<space_id>",
    UsePreviewApi = true
var client = new ContentfulClient(httpClient, options);


To get your own content from Contentful, an app should authenticate with an OAuth bearer token.

You can create API keys using the Contentful web interface. Go to the app, open the space that you want to access (top left corner lists all the spaces), and navigate to the APIs area. Open the API Keys section and create your first token. Done.

For more information, check the Contentful REST API reference on Authentication.
