Step by Step Guide to Building a TeamUp API Integration in C#

Introduction

Hey there, fellow developer! Ready to dive into the world of TeamUp API integration? You're in for a treat. TeamUp's API is a powerful tool that'll let you tap into their calendar and event management features. In this guide, we'll walk through building a solid integration that'll have you manipulating calendars like a pro.

Prerequisites

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

• Visual Studio or your C# IDE of choice
• .NET Core 3.1 or later
• A TeamUp account with API access (grab your API key from the dashboard)

Got all that? Great! Let's get our hands dirty.

Setting up the project

Fire up Visual Studio and create a new C# project. We'll be using a console app for simplicity, but feel free to adapt this to your needs.

Next, let's grab some NuGet packages:

Install-Package Newtonsoft.Json
Install-Package RestSharp

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

Authentication

TeamUp uses API key authentication. Let's set up a base HTTP client:

using RestSharp;

public class TeamUpClient
{
    private readonly RestClient _client;
    private readonly string _apiKey;

    public TeamUpClient(string apiKey)
    {
        _apiKey = apiKey;
        _client = new RestClient("https://api.teamup.com");
    }

    // We'll add methods here soon!
}

Basic API Requests

Now, let's add some methods to make API calls:

public async Task<string> GetAsync(string endpoint)
{
    var request = new RestRequest(endpoint);
    request.AddHeader("Teamup-Token", _apiKey);

    var response = await _client.ExecuteAsync(request);
    return response.Content;
}

public async Task<string> PostAsync(string endpoint, object payload)
{
    var request = new RestRequest(endpoint, Method.Post);
    request.AddHeader("Teamup-Token", _apiKey);
    request.AddJsonBody(payload);

    var response = await _client.ExecuteAsync(request);
    return response.Content;
}

Working with TeamUp Resources

Let's put these methods to use! Here's how you might fetch calendars:

public async Task<List<Calendar>> GetCalendars()
{
    var response = await GetAsync("/calendars");
    return JsonConvert.DeserializeObject<List<Calendar>>(response);
}

And create an event:

public async Task<Event> CreateEvent(string calendarId, Event newEvent)
{
    var response = await PostAsync($"/calendars/{calendarId}/events", newEvent);
    return JsonConvert.DeserializeObject<Event>(response);
}

Error Handling and Rate Limiting

TeamUp's API has rate limits, so let's add some retry logic:

public async Task<T> ExecuteWithRetry<T>(Func<Task<T>> action, int maxRetries = 3)
{
    for (int i = 0; i < maxRetries; i++)
    {
        try
        {
            return await action();
        }
        catch (Exception ex) when (ex.Message.Contains("rate limit"))
        {
            if (i == maxRetries - 1) throw;
            await Task.Delay(1000 * (i + 1));
        }
    }
    throw new Exception("Max retries reached");
}

Advanced Features

Want to stay up-to-date with calendar changes? Set up a webhook:

public async Task<string> CreateWebhook(string calendarId, string url)
{
    var payload = new { url = url };
    return await PostAsync($"/calendars/{calendarId}/webhook", payload);
}

Testing and Debugging

Always test your API calls! Here's a quick unit test example:

[Fact]
public async Task GetCalendars_ReturnsCalendars()
{
    var client = new TeamUpClient("your-api-key");
    var calendars = await client.GetCalendars();
    Assert.NotEmpty(calendars);
}

Best Practices

• Keep your API key secure. Use environment variables or secure storage.
• Organize your code into logical classes (Calendars, Events, Users, etc.).
• Use async/await consistently for better performance.

Conclusion

And there you have it! You've just built a robust TeamUp API integration. You're now equipped to create, manage, and sync calendars and events like a boss. Remember, the API documentation is your friend for diving deeper into specific endpoints.

Happy coding, and may your calendars always be in sync! 🚀📅
