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

Introduction

Hey there, fellow developer! Ready to dive into the world of OnceHub API integration? You're in for a treat. OnceHub's API is a powerful tool that lets you seamlessly incorporate scheduling functionality into your C# applications. In this guide, we'll walk through the process of building a robust integration that'll have you scheduling like a pro in no time.

Prerequisites

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

• Visual Studio or your favorite C# IDE
• .NET Core 3.1 or later
• OnceHub API credentials (if you don't have these yet, hop over to the OnceHub developer portal and grab 'em)

Setting Up the Project

Let's get this show on the road:

1. Fire up Visual Studio and create a new C# project.
2. Install the following NuGet packages:

   Install-Package Newtonsoft.Json
   Install-Package RestSharp
   

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

Authentication

OnceHub uses API key authentication. Here's how to implement it:

private const string API_KEY = "your_api_key_here";
private const string BASE_URL = "https://api.oncehub.com/v2";

var client = new RestClient(BASE_URL);
client.AddDefaultHeader("Authorization", $"Bearer {API_KEY}");

Pro tip: Always keep your API key secret and never commit it to version control. Use environment variables or a secure configuration manager in production.

Making API Requests

Let's create a base API client to handle our requests:

public class OnceHubClient
{
    private readonly RestClient _client;

    public OnceHubClient(string apiKey)
    {
        _client = new RestClient(BASE_URL);
        _client.AddDefaultHeader("Authorization", $"Bearer {apiKey}");
    }

    public async Task<T> GetAsync<T>(string endpoint)
    {
        var request = new RestRequest(endpoint, Method.GET);
        var response = await _client.ExecuteAsync<T>(request);
        return response.Data;
    }

    // Implement Post, Put, Delete methods similarly
}

Implementing Key OnceHub Features

Now for the fun part! Let's implement some core features:

Retrieving Booking Pages

public async Task<List<BookingPage>> GetBookingPagesAsync()
{
    return await GetAsync<List<BookingPage>>("/booking_pages");
}

Creating a Booking

public async Task<Booking> CreateBookingAsync(BookingRequest bookingRequest)
{
    var request = new RestRequest("/bookings", Method.POST);
    request.AddJsonBody(bookingRequest);
    var response = await _client.ExecuteAsync<Booking>(request);
    return response.Data;
}

Error Handling and Logging

Always expect the unexpected:

try
{
    var bookingPages = await client.GetBookingPagesAsync();
}
catch (Exception ex)
{
    _logger.LogError($"Error retrieving booking pages: {ex.Message}");
    // Handle the error appropriately
}

Testing the Integration

Unit testing is your friend:

[Fact]
public async Task GetBookingPages_ReturnsListOfBookingPages()
{
    var client = new OnceHubClient("test_api_key");
    var result = await client.GetBookingPagesAsync();
    Assert.NotNull(result);
    Assert.IsType<List<BookingPage>>(result);
}

Best Practices and Optimization

Remember to respect rate limits and implement caching where appropriate. For example:

private static readonly MemoryCache _cache = new MemoryCache(new MemoryCacheOptions());

public async Task<List<BookingPage>> GetBookingPagesAsync()
{
    if (_cache.TryGetValue("booking_pages", out List<BookingPage> cachedPages))
    {
        return cachedPages;
    }

    var pages = await GetAsync<List<BookingPage>>("/booking_pages");
    _cache.Set("booking_pages", pages, TimeSpan.FromMinutes(5));
    return pages;
}

Conclusion

And there you have it! You've just built a solid foundation for your OnceHub API integration in C#. Remember, this is just the beginning – there's a whole world of scheduling possibilities waiting for you to explore.

Keep experimenting, keep coding, and most importantly, keep having fun! If you hit any snags, the OnceHub API documentation is your best friend. Now go forth and schedule like a boss! 🚀
