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

Introduction

Hey there, fellow developer! Ready to supercharge your landing page game with Landingi's API? Let's dive into building a robust C# integration that'll have you creating, managing, and analyzing landing pages like a pro.

Prerequisites

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

• Visual Studio or your favorite C# IDE
• .NET Core 3.1 or later
• A Landingi account with API access (grab those credentials!)

Setting up the project

Fire up your IDE and let's get this show on the road:

1. Create a new C# project (Console App will do for now)
2. Install the following NuGet packages:

   Install-Package Newtonsoft.Json
   Install-Package RestSharp
   

Authentication

Landingi uses API key authentication. Let's create a base client to handle this:

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

    public LandingiClient(string apiKey)
    {
        _apiKey = apiKey;
        _client = new RestClient("https://api.landingi.com/v1/");
    }

    protected RestRequest CreateRequest(string resource, Method method)
    {
        var request = new RestRequest(resource, method);
        request.AddHeader("Authorization", $"ApiKey {_apiKey}");
        return request;
    }

    // We'll add more methods here soon!
}

Core API Operations

Now, let's implement some key operations:

Retrieving landing pages

public async Task<List<LandingPage>> GetLandingPagesAsync()
{
    var request = CreateRequest("landing_pages", Method.GET);
    var response = await _client.ExecuteAsync<List<LandingPage>>(request);
    return response.Data;
}

Creating a new landing page

public async Task<LandingPage> CreateLandingPageAsync(string name, string templateId)
{
    var request = CreateRequest("landing_pages", Method.POST);
    request.AddJsonBody(new { name, template_id = templateId });
    var response = await _client.ExecuteAsync<LandingPage>(request);
    return response.Data;
}

Updating an existing landing page

public async Task<LandingPage> UpdateLandingPageAsync(string pageId, string name)
{
    var request = CreateRequest($"landing_pages/{pageId}", Method.PUT);
    request.AddJsonBody(new { name });
    var response = await _client.ExecuteAsync<LandingPage>(request);
    return response.Data;
}

Deleting a landing page

public async Task DeleteLandingPageAsync(string pageId)
{
    var request = CreateRequest($"landing_pages/{pageId}", Method.DELETE);
    await _client.ExecuteAsync(request);
}

Handling API Responses

RestSharp handles a lot of the heavy lifting, but let's add some error handling:

private void HandleResponse(IRestResponse response)
{
    if (!response.IsSuccessful)
    {
        throw new ApiException(response.StatusCode, response.Content);
    }
}

Add this to each method before returning the response.

Implementing Additional Features

Retrieving form submissions

public async Task<List<FormSubmission>> GetFormSubmissionsAsync(string pageId)
{
    var request = CreateRequest($"landing_pages/{pageId}/submissions", Method.GET);
    var response = await _client.ExecuteAsync<List<FormSubmission>>(request);
    HandleResponse(response);
    return response.Data;
}

Best Practices

• Implement rate limiting to avoid hitting API limits
• Cache responses where appropriate to reduce API calls
• Log all API interactions for debugging and monitoring

Testing the Integration

Don't forget to test! Here's a quick unit test example:

[Fact]
public async Task GetLandingPages_ReturnsListOfPages()
{
    var client = new LandingiClient("your-api-key");
    var pages = await client.GetLandingPagesAsync();
    Assert.NotNull(pages);
    Assert.True(pages.Count > 0);
}

Conclusion

And there you have it! You've just built a solid foundation for your Landingi API integration. Remember, this is just the beginning - there's so much more you can do with the API. Keep exploring, keep coding, and most importantly, keep creating awesome landing pages!

Happy coding, and may your conversion rates always be high! 🚀
