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

Introduction

Hey there, fellow developer! Ready to supercharge your workflow with BitBucket's API? You're in the right place. We're going to walk through building a BitBucket API integration using C# and the awesome SharpBucket package. This guide is all about getting you up and running quickly, so let's dive in!

Prerequisites

Before we start coding, make sure you've got:

• Visual Studio or your favorite C# IDE
• A BitBucket account (duh!)
• Your BitBucket API credentials (we'll cover this, don't worry)

Setting up the project

First things first, let's create a new C# project. Fire up Visual Studio, create a new Console App (.NET Core), and give it a cool name.

Now, let's grab SharpBucket. In your Package Manager Console, type:

Install-Package SharpBucket

Boom! You're ready to roll.

Initializing SharpBucket client

Alright, let's get that SharpBucket client up and running. You've got two options for authentication: OAuth or Basic. Here's how to set up both:

using SharpBucket.V2;

// OAuth
var sharpBucket = new SharpBucketV2()
    .WithOAuth2ClientCredentials("your_client_id", "your_client_secret");

// Basic Auth
var sharpBucket = new SharpBucketV2()
    .WithBasicAuthentication("your_username", "your_password");

Choose your fighter and let's move on!

Basic API operations

Now that we're connected, let's try some basic operations:

// Get user info
var userInfo = sharpBucket.UserEndPoint().GetUser();
Console.WriteLine($"Hello, {userInfo.DisplayName}!");

// List repositories
var repos = sharpBucket.RepositoriesEndPoint().ListRepositories();
foreach (var repo in repos)
{
    Console.WriteLine(repo.Name);
}

// Get repo details
var repoDetails = sharpBucket.RepositoriesEndPoint()
    .RepositoryResource("owner", "repo_slug")
    .GetRepository();

Easy peasy, right?

Working with issues

Let's create, update, and list some issues:

var issuesResource = sharpBucket.RepositoriesEndPoint()
    .RepositoryResource("owner", "repo_slug")
    .IssuesResource();

// Create an issue
var newIssue = issuesResource.PostIssue(new Issue { Title = "New Bug", Content = "This is a bug" });

// Update an issue
newIssue.Content = "This is an updated bug description";
issuesResource.PutIssue(newIssue);

// List issues
var issues = issuesResource.ListIssues();

Managing pull requests

Time to handle some PRs:

var pullRequestsResource = sharpBucket.RepositoriesEndPoint()
    .RepositoryResource("owner", "repo_slug")
    .PullRequestsResource();

// Create a PR
var newPR = pullRequestsResource.PostPullRequest(new PullRequest
{
    Title = "New feature",
    Source = new Source { Branch = new Branch { Name = "feature-branch" } },
    Destination = new Source { Branch = new Branch { Name = "main" } }
});

// Get PR details
var prDetails = pullRequestsResource.GetPullRequest(newPR.Id);

// Merge a PR
pullRequestsResource.AcceptAndMergePullRequest(newPR.Id);

Handling webhooks

Webhooks are a bit trickier, but here's a basic setup:

// You'll need to set up a web server to listen for POST requests
// This is just a conceptual example
app.Post("/webhook", async (context) =>
{
    using var reader = new StreamReader(context.Request.Body);
    var payload = await reader.ReadToEndAsync();
    
    // Process the webhook payload
    ProcessWebhook(payload);
});

void ProcessWebhook(string payload)
{
    // Parse the JSON payload and handle the event
    // You might want to use a library like Newtonsoft.Json for this
}

Error handling and best practices

Always wrap your API calls in try-catch blocks:

try
{
    var repos = sharpBucket.RepositoriesEndPoint().ListRepositories();
}
catch (SharpBucketException ex)
{
    Console.WriteLine($"Oops! Something went wrong: {ex.Message}");
}

And don't forget about rate limiting! SharpBucket handles this for you, but it's good to be aware of it.

Conclusion

And there you have it! You're now equipped to integrate BitBucket into your C# projects like a pro. Remember, this is just scratching the surface - there's so much more you can do with the BitBucket API and SharpBucket.

Keep exploring, keep coding, and most importantly, have fun! If you get stuck, the SharpBucket documentation and BitBucket API docs are your best friends.

Now go forth and build something awesome! 🚀
