Introduction

Hey there, fellow developer! Ready to supercharge your CRM game with Follow Up Boss? Let's dive into building a slick API integration using C#. We'll cover everything you need to know to get up and running quickly.

Prerequisites

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

Visual Studio or your favorite C# IDE
.NET Core 3.1 or later
A Follow Up Boss account with API access

Got all that? Great! Let's roll.

Setting up the project

First things first, fire up Visual Studio and create a new C# project. We'll be using a console app for this guide, but feel free to adapt it to your needs.

Now, let's grab some NuGet packages:

Install-Package Newtonsoft.Json
Install-Package RestSharp

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

Authentication

Follow Up Boss uses API key authentication. It's straightforward:

private const string ApiKey = "your-api-key-here";
private const string BaseUrl = "https://api.followupboss.com/v1/";

Pro tip: Always keep your API key safe and out of version control!

Making API requests

Let's create a base API client class:

public class FollowUpBossClient
{
    private readonly RestClient _client;

    public FollowUpBossClient(string apiKey)
    {
        _client = new RestClient(BaseUrl);
        _client.AddDefaultHeader("Authorization", $"Basic {Convert.ToBase64String(Encoding.ASCII.GetBytes($"{apiKey}:"))}");
    }

    public async Task<T> ExecuteAsync<T>(RestRequest request)
    {
        var response = await _client.ExecuteAsync<T>(request);
        if (!response.IsSuccessful)
        {
            throw new Exception($"API request failed: {response.ErrorMessage}");
        }
        return response.Data;
    }
}

Implementing core functionalities

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

Fetching contacts

public async Task<List<Contact>> GetContactsAsync()
{
    var request = new RestRequest("contacts", Method.GET);
    return await ExecuteAsync<List<Contact>>(request);
}

Creating new contacts

public async Task<Contact> CreateContactAsync(Contact contact)
{
    var request = new RestRequest("contacts", Method.POST);
    request.AddJsonBody(contact);
    return await ExecuteAsync<Contact>(request);
}

Updating existing contacts

public async Task<Contact> UpdateContactAsync(int contactId, Contact contact)
{
    var request = new RestRequest($"contacts/{contactId}", Method.PUT);
    request.AddJsonBody(contact);
    return await ExecuteAsync<Contact>(request);
}

Error handling and logging

Don't forget to wrap your API calls in try-catch blocks and log any errors:

try
{
    var contacts = await client.GetContactsAsync();
}
catch (Exception ex)
{
    Console.WriteLine($"Error fetching contacts: {ex.Message}");
    // Log the error
}

Testing the integration

Always test your integration thoroughly. Write unit tests for your methods and integration tests that actually hit the API (but use a sandbox environment if available).

Best practices and optimization

Remember to respect rate limits and implement caching where it makes sense. Your future self will thank you!

Conclusion

And there you have it! You've just built a solid foundation for your Follow Up Boss API integration. From here, you can expand on this base to implement more advanced features and really make it sing.
