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

Introduction

Hey there, fellow developer! Ready to dive into the world of MemberPress API integration? You're in the right place. We'll be using the nifty wp-pay-extensions/memberpress package to make our lives easier. Let's get cracking!

Prerequisites

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

• A PHP environment (you're a pro, so I'm sure you've got this)
• WordPress installation (up and running, right?)
• MemberPress plugin (installed and activated)
• Composer (because who doesn't love dependency management?)

Installation

First things first, let's get our hands on that wp-pay-extensions/memberpress package. Fire up your terminal and run:

composer require wp-pay-extensions/memberpress

Easy peasy, right?

Configuration

Now, let's set things up:

1. Grab your MemberPress API credentials from your MemberPress dashboard.
2. Create a config file (let's call it memberpress-config.php) and add your credentials:

<?php
return [
    'api_key' => 'your_api_key_here',
    'api_secret' => 'your_api_secret_here'
];

Basic Usage

Time to get our hands dirty! Let's initialize the MemberPress client:

<?php
require_once 'vendor/autoload.php';

$config = require 'memberpress-config.php';

$client = new \WPPayMemberPress\Client($config['api_key'], $config['api_secret']);

Boom! You're authenticated and ready to roll.

Common API Operations

Let's run through some everyday tasks:

Retrieving Members

$members = $client->getMembers();
foreach ($members as $member) {
    echo $member->email . "\n";
}

Creating a New Member

$newMember = $client->createMember([
    'email' => '[email protected]',
    'username' => 'newuser',
    'password' => 'securepassword123'
]);

Updating Member Information

$updatedMember = $client->updateMember($memberId, [
    'first_name' => 'John',
    'last_name' => 'Doe'
]);

Handling Subscriptions

$subscriptions = $client->getMemberSubscriptions($memberId);

Error Handling

Nobody's perfect, and neither are APIs. Let's catch those errors:

try {
    $result = $client->someApiCall();
} catch (\WPPayMemberPress\Exception\ApiException $e) {
    echo "Oops! " . $e->getMessage();
}

Advanced Usage

Webhooks Integration

MemberPress can send webhooks. Here's a basic receiver:

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

if ($event['type'] === 'subscription.created') {
    // Handle new subscription
}

Custom API Requests

Need something specific? No problem:

$response = $client->request('GET', '/custom/endpoint');

Performance Considerations

• Use caching for frequently accessed data.
• Respect rate limits. Maybe add a delay between requests if you're doing bulk operations.

Security Best Practices

• Never, ever commit your API credentials to version control.
• Always validate and sanitize input before sending it to the API.

Testing

Unit testing is your friend. Here's a quick example using PHPUnit:

public function testCreateMember()
{
    $client = $this->createMock(\WPPayMemberPress\Client::class);
    $client->expects($this->once())
           ->method('createMember')
           ->willReturn(new \WPPayMemberPress\Member(['id' => 1]));

    $result = $client->createMember([/* ... */]);
    $this->assertInstanceOf(\WPPayMemberPress\Member::class, $result);
}

Conclusion

And there you have it! You're now equipped to integrate MemberPress into your PHP application like a boss. Remember, the API is your oyster - explore, experiment, and build something awesome!
