Step by Step Guide to Building a Customer.io API Integration in PHP

Introduction

Hey there, fellow developer! Ready to supercharge your PHP application with some Customer.io goodness? You're in the right place. We're going to walk through integrating the Customer.io API using the awesome printu/customerio package. It's going to be a breeze, I promise!

Prerequisites

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

• PHP 7.4 or higher (come on, you're not still using PHP 5, right?)
• Composer installed (because who wants to manage dependencies manually?)

Installation

Let's kick things off by installing the printu/customerio package. Fire up your terminal and run:

composer require printu/customerio

Easy peasy, right?

Configuration

Now, let's get you set up with Customer.io:

1. Head over to your Customer.io account and grab your API credentials.
2. Got 'em? Great! Let's set up the Customer.io client:

use Customerio\Client;

$client = new Client('your-site-id', 'your-api-key');

Basic Usage

Alright, time to get our hands dirty! Here's how you initialize the Customer.io client:

$customerio = new Client('your-site-id', 'your-api-key');

Pro tip: Wrap this in a try-catch block to handle any exceptions. Trust me, your future self will thank you.

Key API Operations

Managing Customers

Creating or updating a customer? It's as simple as:

$customerio->customers->add('[email protected]', [
    'name' => 'John Doe',
    'plan' => 'premium'
]);

Need to show a customer the door? No problem:

$customerio->customers->delete('[email protected]');

Tracking Events

Caught your user doing something cool? Let's track it:

$customerio->events->track('[email protected]', 'purchased', [
    'item' => 'Awesome Gadget',
    'price' => 99.99
]);

Segments

Want to add a customer to a segment? Easy:

$customerio->segments->add('segment-id', '[email protected]');

Campaigns

Trigger a campaign like a boss:

$customerio->campaigns->trigger('campaign-id', '[email protected]', [
    'product' => 'Super Widget'
]);

Advanced Usage

Ready to level up? Let's talk batch operations:

$customerio->customers->addBatch([
    ['id' => '[email protected]', 'data' => ['name' => 'Alice']],
    ['id' => '[email protected]', 'data' => ['name' => 'Bob']]
]);

Best Practices

Remember to:

• Keep an eye on those rate limits. Customer.io isn't your personal punching bag.
• Log errors like your life depends on it. Future you will be grateful.

Testing

Unit testing your integration? Good on you! Here's a quick example:

use PHPUnit\Framework\TestCase;
use Customerio\Client;

class CustomerioTest extends TestCase
{
    public function testAddCustomer()
    {
        $mock = $this->createMock(Client::class);
        $mock->expects($this->once())
             ->method('add')
             ->with('[email protected]', ['name' => 'Test User'])
             ->willReturn(true);

        $this->assertTrue($mock->add('[email protected]', ['name' => 'Test User']));
    }
}

Conclusion

And there you have it! You're now armed and dangerous with Customer.io integration skills. Remember, the official documentation is your friend if you need more details.
