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

Introduction

Hey there, fellow developer! Ready to supercharge your PHP project with Landingi's powerful API? You're in the right place. This guide will walk you through integrating Landingi's API into your PHP application, giving you the ability to create, manage, and analyze landing pages programmatically. Let's dive in!

Prerequisites

Before we get our hands dirty, make sure you've got:

• A PHP environment (7.4+ recommended)
• Landingi API credentials (if you don't have these, hop over to your Landingi account and generate them)
• Composer installed (we'll use this to manage dependencies)

Got all that? Great! Let's move on.

Setting up the API Client

First things first, let's get our project set up:

composer require guzzlehttp/guzzle

This installs Guzzle, which we'll use to make HTTP requests. Now, let's create a simple API client:

<?php

use GuzzleHttp\Client;

class LandingiClient
{
    private $client;
    private $apiKey;

    public function __construct($apiKey)
    {
        $this->apiKey = $apiKey;
        $this->client = new Client([
            'base_uri' => 'https://api.landingi.com/v1/',
            'headers' => [
                'Authorization' => 'Bearer ' . $this->apiKey,
                'Accept' => 'application/json',
            ],
        ]);
    }

    // We'll add more methods here soon!
}

Authentication

Landingi uses OAuth 2.0 for authentication. In this example, we're using an API key for simplicity. In a production environment, you might want to implement the full OAuth flow.

Basic API Operations

Let's add some methods to our LandingiClient class to handle basic operations:

public function getLandingPages()
{
    $response = $this->client->get('landing_pages');
    return json_decode($response->getBody(), true);
}

public function createLandingPage($data)
{
    $response = $this->client->post('landing_pages', ['json' => $data]);
    return json_decode($response->getBody(), true);
}

public function updateLandingPage($id, $data)
{
    $response = $this->client->put("landing_pages/{$id}", ['json' => $data]);
    return json_decode($response->getBody(), true);
}

public function deleteLandingPage($id)
{
    $response = $this->client->delete("landing_pages/{$id}");
    return $response->getStatusCode() === 204;
}

Working with Forms

Forms are a crucial part of landing pages. Let's add methods to handle them:

public function getFormData($landingPageId)
{
    $response = $this->client->get("landing_pages/{$landingPageId}/forms");
    return json_decode($response->getBody(), true);
}

public function submitFormEntry($formId, $data)
{
    $response = $this->client->post("forms/{$formId}/entries", ['json' => $data]);
    return json_decode($response->getBody(), true);
}

Handling Webhooks

Webhooks allow you to receive real-time updates. Here's a simple webhook handler:

public function handleWebhook($payload)
{
    $event = $payload['event'];
    $data = $payload['data'];

    switch ($event) {
        case 'form_submitted':
            // Handle form submission
            break;
        case 'page_published':
            // Handle page publication
            break;
        // Add more cases as needed
    }
}

Error Handling and Logging

Don't forget to wrap your API calls in try-catch blocks and log responses:

try {
    $pages = $client->getLandingPages();
    // Process $pages
} catch (\Exception $e) {
    // Log the error
    error_log('Error fetching landing pages: ' . $e->getMessage());
}

Best Practices

1. Respect rate limits: Landingi has rate limits, so implement exponential backoff if you hit them.
2. Cache responses when appropriate to reduce API calls.
3. Use webhook events for real-time updates instead of polling the API.

Testing the Integration

Always test your integration thoroughly. Here's a simple PHPUnit test example:

public function testGetLandingPages()
{
    $client = new LandingiClient('your-api-key');
    $pages = $client->getLandingPages();
    $this->assertIsArray($pages);
    $this->assertArrayHasKey('id', $pages[0]);
}

Conclusion

And there you have it! You've just built a solid foundation for integrating Landingi's API into your PHP project. Remember, this is just the beginning - there's so much more you can do with the API. Keep exploring, keep coding, and most importantly, keep creating awesome landing pages!
