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

Introduction

Hey there, fellow developer! Ready to dive into the world of Mautic API integration? You're in the right place. We'll be using the mautic/api-library package to make our lives easier. Let's get cracking!

Prerequisites

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

• A PHP environment (you're a pro, so I'm sure you've got this covered)
• Composer installed (because who doesn't love dependency management?)
• A Mautic instance with API access (if you don't have this, go bug your admin!)

Installation

First things first, let's get that mautic/api-library installed:

composer require mautic/api-library

Easy peasy, right?

Authentication

Now, let's tackle OAuth2 authentication:

1. Set up OAuth2 in your Mautic instance (you'll need those client credentials)
2. In your PHP code, implement OAuth2 like this:

use Mautic\Auth\ApiAuth;

$auth = new ApiAuth();
$credentials = [
    'clientKey'    => 'your_client_id',
    'clientSecret' => 'your_client_secret',
    'callback'     => 'https://your-callback-url.com'
];
$authorizationUrl = $auth->newAuth($credentials, 'OAuth2');

// Redirect user to $authorizationUrl, then handle the callback

Basic API Usage

Let's get that API client up and running:

use Mautic\MauticApi;

$api = new MauticApi();
$contactApi = $api->newApi('contacts', $auth, 'https://your-mautic-instance.com');

// Fetch contacts
$contacts = $contactApi->getList();

Common API Operations

Here are some operations you'll probably use a lot:

// Create a contact
$newContact = $contactApi->create(['email' => '[email protected]']);

// Update a contact
$updatedContact = $contactApi->edit(123, ['firstname' => 'John']);

// Delete a contact
$contactApi->delete(123);

// Fetch segments
$segmentApi = $api->newApi('segments', $auth, 'https://your-mautic-instance.com');
$segments = $segmentApi->getList();

// Add contact to segment
$segmentApi->addContact(456, 123); // segmentId, contactId

Handling API Responses

Always check those responses:

if ($contacts['total'] > 0) {
    foreach ($contacts['contacts'] as $contact) {
        // Do something with each contact
    }
} else {
    // Handle no contacts found
}

Advanced Usage

Want to level up? Try these:

// Pagination
$contacts = $contactApi->getList($start, $limit, $orderBy, $orderByDir, $publishedOnly, $minimal);

// Filtering
$contacts = $contactApi->getList(0, 100, null, null, null, null, [
    'search' => 'email:*@example.com',
    'orderBy' => 'email',
    'orderByDir' => 'DESC'
]);

// Batch operations
$batchApi = $api->newApi('contacts', $auth, 'https://your-mautic-instance.com');
$batchApi->createBatch([
    ['email' => '[email protected]'],
    ['email' => '[email protected]']
]);

Best Practices

1. Mind those rate limits! Mautic isn't built for rapid-fire requests.
2. Cache when you can. Your server (and Mautic's) will thank you.
3. Log errors and monitor your integration. Trust me, future you will appreciate it.

Conclusion

And there you have it! You're now armed with the knowledge to build a solid Mautic API integration. Remember, the official Mautic API documentation is your friend for more in-depth info.

Now go forth and integrate! You've got this. 💪
