Step by Step Guide to Building an Any.do API Integration in C#

Introduction

Hey there, fellow code wrangler! Ready to supercharge your productivity app with the power of Any.do? Let's dive into building a slick API integration that'll have you managing tasks like a boss. We'll be using C# because, let's face it, it's awesome.

Prerequisites

Before we jump in, make sure you've got:

• Visual Studio or your favorite C# IDE
• .NET Core SDK (latest stable version)
• An Any.do account (duh!)
• Coffee (optional, but highly recommended)

Oh, and don't forget to grab your Any.do API key. You'll need it to make friends with their servers.

Setting up the project

Fire up Visual Studio and create a new C# project. We're going for a console app to keep things simple, but feel free to get fancy if you want.

Now, let's grab some NuGet packages:

Install-Package Newtonsoft.Json
Install-Package RestSharp

These bad boys will make our lives easier when dealing with JSON and HTTP requests.

Authentication

Any.do uses OAuth 2.0, so we need to do a little dance to get our access token. Here's the quick and dirty:

var client = new RestClient("https://api.any.do/oauth/token");
var request = new RestRequest(Method.POST);
request.AddParameter("grant_type", "password");
request.AddParameter("username", "your_email");
request.AddParameter("password", "your_password");
request.AddParameter("client_id", "your_client_id");

IRestResponse response = client.Execute(request);
var token = JsonConvert.DeserializeObject<TokenResponse>(response.Content);

Store that token somewhere safe – you'll need it for all your API shenanigans.

Basic API Requests

Now that we're authenticated, let's make our first request:

var client = new RestClient("https://api.any.do/me/tasks");
var request = new RestRequest(Method.GET);
request.AddHeader("Authorization", $"Bearer {token.AccessToken}");

IRestResponse response = client.Execute(request);
var tasks = JsonConvert.DeserializeObject<List<Task>>(response.Content);

Boom! You've just fetched all your tasks. Feel the power!

CRUD Operations

Let's create, read, update, and delete some tasks:

// Create
var newTask = new Task { Title = "Build awesome Any.do integration" };
var createRequest = new RestRequest(Method.POST);
createRequest.AddJsonBody(newTask);

// Read
var getRequest = new RestRequest($"tasks/{taskId}", Method.GET);

// Update
var updateRequest = new RestRequest($"tasks/{taskId}", Method.PATCH);
updateRequest.AddJsonBody(new { Title = "Updated task title" });

// Delete
var deleteRequest = new RestRequest($"tasks/{taskId}", Method.DELETE);

Remember to add the authorization header to each request!

Advanced Features

Want to work with lists or tags? It's just as easy:

// Get all lists
var listsRequest = new RestRequest("me/lists", Method.GET);

// Add a tag to a task
var addTagRequest = new RestRequest($"tasks/{taskId}/tags", Method.POST);
addTagRequest.AddJsonBody(new { Name = "Important" });

Error Handling and Rate Limiting

Be a good API citizen and handle those errors:

if (response.StatusCode != HttpStatusCode.OK)
{
    Console.WriteLine($"Oops! {response.StatusCode}: {response.ErrorMessage}");
}

And don't forget about rate limits. Add some retry logic if you're hitting the API hard.

Asynchronous Operations

Make your app snappy with async calls:

var response = await client.ExecuteAsync(request);

Your UI will thank you.

Testing and Debugging

Write some unit tests, folks. Your future self will be grateful:

[Test]
public async Task GetTasks_ReturnsTaskList()
{
    // Arrange
    var api = new AnyDoApi(mockHttpClient);

    // Act
    var tasks = await api.GetTasksAsync();

    // Assert
    Assert.IsNotEmpty(tasks);
}

Best Practices

• Keep your API key and tokens secure
• Use dependency injection for better testability
• Handle API responses gracefully

Conclusion

And there you have it! You've just built a rockin' Any.do API integration in C#. Go forth and conquer those tasks like the coding ninja you are. Remember, with great power comes great responsibility – use your new skills wisely!
