Step by Step Guide to Building an Interact API Integration in PHP

Introduction

Hey there, fellow code wranglers! Ready to dive into the world of Interact API integration? You're in for a treat. We'll be walking through the process of building a robust PHP integration that'll have you interacting with Interact like a pro in no time.

Prerequisites

Before we jump in, let's make sure we've got our ducks in a row:

• PHP 7.4 or higher (because who doesn't love those sweet, sweet type hints?)
• Composer (your friendly neighborhood dependency manager)
• Interact API credentials (you've got these, right?)

Setting up the environment

First things first, let's get our environment ship-shape:

composer require guzzlehttp/guzzle

Now, let's stash those API credentials somewhere safe. Create a .env file and add:

INTERACT_API_KEY=your_api_key_here
INTERACT_API_SECRET=your_api_secret_here

Basic API Connection

Time to get our hands dirty! Let's create an API client:

use GuzzleHttp\Client;

$client = new Client([
    'base_uri' => 'https://api.interact.io/v2/',
    'headers' => [
        'Authorization' => 'Bearer ' . getenv('INTERACT_API_KEY'),
        'Content-Type' => 'application/json',
    ],
]);

Core API Operations

Fetching data

Let's grab some data, shall we?

$response = $client->get('contacts');
$contacts = json_decode($response->getBody(), true);

Creating resources

Time to add a new contact:

$newContact = [
    'name' => 'Jane Doe',
    'email' => '[email protected]',
];

$response = $client->post('contacts', ['json' => $newContact]);

Updating resources

Oops, Jane got married. Let's update her name:

$updatedContact = ['name' => 'Jane Smith'];
$response = $client->put('contacts/123', ['json' => $updatedContact]);

Deleting resources

Farewell, Jane:

$response = $client->delete('contacts/123');

Error Handling and Logging

Let's not let those pesky errors slip through the cracks:

try {
    $response = $client->get('contacts');
} catch (\GuzzleHttp\Exception\RequestException $e) {
    error_log('API request failed: ' . $e->getMessage());
}

Pagination and Rate Limiting

Interact's got your back with pagination. Here's how to handle it:

$page = 1;
do {
    $response = $client->get('contacts', ['query' => ['page' => $page]]);
    $contacts = json_decode($response->getBody(), true);
    // Process $contacts...
    $page++;
} while (!empty($contacts));

As for rate limiting, be a good API citizen:

$response = $client->get('contacts');
$remainingRequests = $response->getHeader('X-RateLimit-Remaining')[0];

if ($remainingRequests < 10) {
    sleep(60); // Take a breather
}

Webhooks

Interact's webhooks are like a bat-signal for your app. Here's how to catch 'em:

$payload = file_get_contents('php://input');
$event = json_decode($payload, true);

switch ($event['type']) {
    case 'contact.created':
        // Handle new contact
        break;
    // Handle other event types...
}

Testing the Integration

Don't forget to test! Here's a quick unit test example:

public function testGetContacts()
{
    $client = $this->createMock(Client::class);
    $client->expects($this->once())
           ->method('get')
           ->with('contacts')
           ->willReturn(new Response(200, [], json_encode(['data' => []])));

    $api = new InteractApi($client);
    $contacts = $api->getContacts();

    $this->assertIsArray($contacts);
}

Best Practices and Optimization

Remember, caching is your friend:

$cacheKey = 'contacts_list';
if ($cache->has($cacheKey)) {
    $contacts = $cache->get($cacheKey);
} else {
    $contacts = $api->getContacts();
    $cache->set($cacheKey, $contacts, 3600); // Cache for an hour
}

Conclusion

And there you have it, folks! You're now armed and dangerous with Interact API integration skills. Remember, the API is your oyster - so get out there and build something awesome!
