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

Introduction

Hey there, fellow code wranglers! Ready to supercharge your email validation game? Let's dive into the world of NeverBounce API integration using C#. We'll be leveraging the nifty NeverBounce.SDK package to make our lives easier. Buckle up!

Prerequisites

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

• Your favorite C# IDE (Visual Studio, Rider, whatever floats your boat)
• NeverBounce API key (if you don't have one, grab it from their website)
• A burning desire to validate emails like a pro

Installation

First things first, let's get that SDK installed:

Install-Package NeverBounce.SDK

Easy peasy, right? Now we're cooking with gas!

Setting up the Client

Time to initialize our NeverBounceClient. It's as simple as:

using NeverBounce.SDK;

var client = new NeverBounceClient("your_api_key_here");

Boom! You're ready to roll.

Core API Functionalities

Single Email Verification

Validating a single email? No sweat:

var result = await client.Single.CheckAsync("[email protected]");
Console.WriteLine($"Result: {result.Result}");

Bulk Email Verification

Got a truckload of emails? We've got you covered:

var job = await client.Jobs.CreateAsync(new[] { "[email protected]", "[email protected]" });
Console.WriteLine($"Job ID: {job.JobId}");

Job Status Checking

Keep tabs on your bulk job:

var status = await client.Jobs.StatusAsync(job.JobId);
Console.WriteLine($"Job Status: {status.JobStatus}");

Result Retrieval

Time to reap what you've sown:

var results = await client.Jobs.ResultsAsync(job.JobId);
foreach (var item in results.Results)
{
    Console.WriteLine($"Email: {item.Email}, Result: {item.Verification.Result}");
}

Error Handling and Best Practices

Don't let errors catch you off guard. Wrap your API calls in try-catch blocks:

try
{
    // Your API call here
}
catch (NeverBounceException ex)
{
    Console.WriteLine($"Oops! {ex.Message}");
}

And remember, respect those rate limits! NeverBounce isn't a fan of spam (ironic, right?).

Advanced Usage

Webhook Integration

Want real-time updates? Set up a webhook:

var webhook = await client.Webhooks.CreateAsync("https://your-webhook-url.com");
Console.WriteLine($"Webhook ID: {webhook.Id}");

Customizing Timeout and Retry Logic

Need more control? You've got it:

var customClient = new NeverBounceClient("your_api_key", new ClientOptions
{
    Timeout = TimeSpan.FromSeconds(30),
    MaxRetries = 3
});

Testing and Validation

Don't forget to test! Mock those API responses:

var mockClient = new Mock<INeverBounceClient>();
mockClient.Setup(c => c.Single.CheckAsync(It.IsAny<string>()))
    .ReturnsAsync(new SingleCheckResult { Result = "valid" });

// Use mockClient in your tests

Performance Optimization

Async all the things! And for bulk operations, embrace batch processing:

var tasks = emails.Select(email => client.Single.CheckAsync(email));
var results = await Task.WhenAll(tasks);

Conclusion

And there you have it, folks! You're now armed and dangerous with NeverBounce API integration skills. Remember, with great power comes great responsibility - use your newfound email validation superpowers wisely!
