createsend-dotnet

A .NET library which implements the complete functionality of the Campaign Monitor API.

This library is supported on .NET 2, .NET 3.5, and .NET 4. You will find solution files which target the different .NET runtime versions: createsend-dotnet.net20.sln, createsend-dotnet.net35.sln, and createsend-dotnet.sln.

Installation

Using NuGet (recommended):

Run Install-Package campaignmonitor-api from the Package Manager Console in Visual Studio. See the NuGet documentation for further details.

If you don't want to use NuGet:

Open the solution file which targets your preferred version of the runtime.
Build the solution in Release mode. You will see a sub-directory in the createsend-dotnet/bin/Release directory, which contains the assemblies targeting your preferred version of the runtime.
Add the resulting assemblies as references in your project.

Authenticating

The Campaign Monitor API supports authentication using either OAuth or an API key.

Using OAuth

This library helps you authenticate using OAuth, as described in the Campaign Monitor API documentation. You may also wish to reference this ASP.NET MVC example application. The authentication process is described below.

The first thing your application should do is redirect your user to the Campaign Monitor authorization URL where they will have the opportunity to approve your application to access their Campaign Monitor account. You can get this authorization URL by using createsend_dotnet.General.AuthorizeUrl(), like so:

string authorizeUrl = createsend_dotnet.General.AuthorizeUrl(
    32132,                 // The Client ID for your application
    "http://example.com/", // Redirect URI for your application
    "ViewReports",         // The permission level your application requires
    "some state data"      // Optional state data to be included
);
// Redirect your users to authorizeUrl.

If your user approves your application, they will then be redirected to the redirect URI you specified, which will include a code parameter, and optionally a state parameter in the query string. Your application should implement a handler which can exchange the code passed to it for an access token, using createsend_dotnet.General.ExchangeToken() like so:

createsend_dotnet.OAuthTokenDetails tokenDetails = createsend_dotnet.General.ExchangeToken(
    32132,                 // The Client ID for your application
    "982u39823r928398",    // The Client Secret for your application
    "http://example.com/", // Redirect URI for your application
    "8dw9uq98wu98d"        // The unique code for your user found in the query string
);
// Save your access token, 'expires in' value, and refresh token (in tokenDetails).

Once you have an access token and refresh token for your user, you can authenticate and make further API calls like so:

using System;
using System.Collections.Generic;
using createsend_dotnet;

namespace dotnet_api_client
{
    class Program
    {
        static void Main(string[] args)
        {
            AuthenticationDetails auth = new OAuthAuthenticationDetails(
                "your access token", "your refresh token");
            var general = new General(auth);
            var clients = general.Clients();
        }
    }
}

All OAuth tokens have an expiry time, and can be renewed with a corresponding refresh token. If your access token expires when attempting to make an API call, a createsend_dotnet.ExpiredOAuthTokenException will be thrown, so your code should handle this. Here's an example of how you could do this:

using System;
using System.Collections.Generic;
using createsend_dotnet;

namespace dotnet_api_client
{
    class Program
    {
        static void Main(string[] args)
        {
            AuthenticationDetails auth = new OAuthAuthenticationDetails(
                "your access token", "your refresh token");
            var general = new General(auth);
            IEnumerable<BasicClient> clients;
            try
            {
                clients = general.Clients();
            }
            catch (ExpiredOAuthTokenException ex)
            {
                OAuthTokenDetails newTokenDetails = general.RefreshToken();
                // Save your updated access token, 'expires in' value, and refresh token
                clients = general.Clients();
            }
        }
    }
}

Using an API key

using System;
using System.Collections.Generic;
using createsend_dotnet;

namespace dotnet_api_client
{
    class Program
    {
        static void Main(string[] args)
        {
            AuthenticationDetails auth = new ApiKeyAuthenticationDetails(
                "your api key");
            var general = new General(auth);
            var clients = general.Clients();
        }
    }
}

Basic usage

This example of listing all your clients and their campaigns demonstrates basic usage of the library and the data returned from the API:

using System;
using System.Collections.Generic;
using createsend_dotnet;

namespace dotnet_api_client
{
    class Program
    {
        static void Main(string[] args)
        {
            AuthenticationDetails auth = new OAuthAuthenticationDetails(
                "your access token", "your refresh token");
            var general = new General(auth);
            IEnumerable<BasicClient> clients = general.Clients();
            foreach (BasicClient c in clients)
            {
                Console.WriteLine(string.Format("Client: {0}", c.Name));
                var cl = new Client(auth, c.ClientID);
                Console.WriteLine("- Campaigns:");
                foreach (CampaignDetail cm in cl.Campaigns())
                    Console.WriteLine(string.Format("  - {0}", cm.Subject));
            }
        }
    }
}
