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

Introduction

Hey there, fellow code wranglers! Ready to dive into the world of Teachable API integration? Buckle up, because we're about to embark on a journey that'll supercharge your e-learning platform with some serious C# magic. We'll be using the TeachableMachine package, so get ready to flex those coding muscles!

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
• A Teachable API key (if you don't have one, hop over to the Teachable dashboard and snag it)

Setting up the project

Let's kick things off by creating a new C# project. Fire up your IDE and create a new Console Application. Once that's done, it's time to invite TeachableMachine to the party:

dotnet add package TeachableMachine

Initializing the Teachable client

Now, let's get that Teachable client up and running:

using TeachableMachine;

var client = new TeachableClient("YOUR_API_KEY_HERE");

Easy peasy, right? Just remember to keep that API key safe – no sharing on GitHub!

Implementing core API functionalities

Time to get our hands dirty with some core functionalities. Let's start with fetching courses:

var courses = await client.GetCoursesAsync();
foreach (var course in courses)
{
    Console.WriteLine($"Course: {course.Name}");
}

Managing users? We've got you covered:

var newUser = await client.CreateUserAsync("[email protected]", "John Doe");

And let's not forget about enrollments:

await client.EnrollUserInCourseAsync(newUser.Id, courseId);

Error handling and best practices

Always expect the unexpected! Wrap your API calls in try-catch blocks:

try
{
    var courses = await client.GetCoursesAsync();
}
catch (TeachableApiException ex)
{
    Console.WriteLine($"Oops! {ex.Message}");
}

And remember, be nice to the API – implement rate limiting to avoid getting the cold shoulder.

Advanced features

Ready to level up? Let's talk webhooks:

client.OnEnrollmentCreated += (sender, enrollment) =>
{
    Console.WriteLine($"New enrollment: {enrollment.UserId} in {enrollment.CourseId}");
};

Testing the integration

Don't forget to test! Here's a quick unit test to get you started:

[Fact]
public async Task GetCourses_ReturnsNonEmptyList()
{
    var courses = await _client.GetCoursesAsync();
    Assert.NotEmpty(courses);
}

Optimizing performance

For the speed demons out there, consider caching frequently accessed data:

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

public async Task<List<Course>> GetCachedCoursesAsync()
{
    if (!_cache.TryGetValue("courses", out List<Course> courses))
    {
        courses = await _client.GetCoursesAsync();
        _cache.Set("courses", courses, TimeSpan.FromMinutes(15));
    }
    return courses;
}

Conclusion

And there you have it, folks! You're now armed with the knowledge to build a robust Teachable API integration in C#. Remember, the API documentation is your best friend, so don't be shy about diving deeper.

Now go forth and create some e-learning magic! Happy coding! 🚀📚
