Step by Step Guide to Building a BitBucket API Integration in PHP

Introduction

Hey there, fellow developer! Ready to dive into the world of BitBucket API integration? You're in the right place. We'll be using the bitbucket/client package to make our lives easier. This guide assumes you're already familiar with PHP and have a good grasp of API concepts. Let's get cracking!

Prerequisites

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

• A PHP environment (you've got this, right?)
• Composer installed (because who doesn't use Composer these days?)
• A BitBucket account with API credentials (if you don't have this, take a quick detour to set it up)

Installation

First things first, let's get that bitbucket/client package installed:

composer require bitbucket/client

Easy peasy, right?

Authentication

Now, let's set up our OAuth consumer in BitBucket:

1. Head over to BitBucket and create a new OAuth consumer
2. Grab your client ID and secret

Here's how to configure the client with your shiny new credentials:

use Bitbucket\Client;

$client = new Client();
$client->authenticate(Client::AUTH_OAuth_TOKEN, 'your_access_token');

Basic Usage

Let's take our client for a spin:

$user = $client->currentUser()->show();
echo "Hello, " . $user['username'] . "!";

Look at that! You're already talking to BitBucket.

Common API Operations

Repositories

List 'em:

$repos = $client->repositories()->list(['username' => 'your_username']);

Create one:

$client->repositories()->create(['username' => 'your_username', 'repo_slug' => 'awesome-repo']);

Get the details:

$repo = $client->repositories()->show('your_username', 'repo_slug');

Pull Requests

List 'em:

$prs = $client->pullRequests()->list('your_username', 'repo_slug');

Create one:

$client->pullRequests()->create('your_username', 'repo_slug', [
    'title' => 'Amazing new feature',
    'source' => ['branch' => ['name' => 'feature-branch']],
    'destination' => ['branch' => ['name' => 'main']]
]);

Merge it:

$client->pullRequests()->merge('your_username', 'repo_slug', $pr_id);

Issues

List 'em:

$issues = $client->issues()->list('your_username', 'repo_slug');

Create one:

$client->issues()->create('your_username', 'repo_slug', [
    'title' => 'Found a bug!',
    'content' => ['raw' => 'This is a detailed description of the bug.']
]);

Update it:

$client->issues()->update('your_username', 'repo_slug', $issue_id, [
    'state' => 'resolved'
]);

Error Handling

Don't forget to catch those pesky exceptions:

use Bitbucket\Exception\BitbucketException;

try {
    // Your API call here
} catch (BitbucketException $e) {
    echo "Oops! " . $e->getMessage();
}

Advanced Usage

Pagination

Dealing with lots of data? Use pagination:

$page = 1;
do {
    $repos = $client->repositories()->list(['username' => 'your_username', 'page' => $page]);
    // Process $repos
    $page++;
} while (!empty($repos));

Webhooks

Listen for BitBucket events:

$client->webhooks()->create('your_username', 'repo_slug', [
    'description' => 'My awesome webhook',
    'url' => 'https://your-server.com/webhook',
    'active' => true,
    'events' => ['repo:push', 'issue:created']
]);

Best Practices

• Mind the rate limits! BitBucket isn't shy about throttling overeager apps.
• Cache responses when you can. Your future self will thank you.

Conclusion

And there you have it! You're now armed and dangerous with BitBucket API integration skills. Remember, the official BitBucket API docs are your best friend for diving deeper.

Now go forth and build something awesome! 🚀
