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

Introduction

Hey there, fellow developer! Ready to dive into the world of customer feedback with Delighted's API? You're in for a treat. This guide will walk you through integrating Delighted's powerful survey tools into your PHP application. Let's get cracking!

Prerequisites

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

• PHP 7.4 or higher (come on, you're not still using 5.6, right?)
• Composer installed (because who wants to manage dependencies manually?)
• A Delighted API key (grab one from your Delighted dashboard)

Setting up the project

First things first, let's get that Delighted PHP library installed:

composer require delighted/delighted-php

Now, let's initialize the Delighted client:

use Delighted\Client;

$client = new Client('your-api-key-here');

Easy peasy, right?

Basic API Operations

Creating a survey response

Let's send out some surveys:

$response = $client->createSurveyResponse([
    'email' => '[email protected]',
    'score' => 9
]);

Retrieving survey responses

Want to see what your customers are saying?

$responses = $client->listSurveyResponses();

Updating a survey response

Oops, made a mistake? No worries:

$client->updateSurveyResponse($responseId, [
    'score' => 10
]);

Deleting a survey response

Sometimes you just need to start fresh:

$client->deleteSurveyResponse($responseId);

Advanced Features

Filtering and pagination

Don't drown in data, filter it:

$responses = $client->listSurveyResponses([
    'per_page' => 50,
    'page' => 2,
    'since' => '2023-01-01'
]);

Handling rate limits

Be nice to the API, it's your friend:

try {
    // Your API calls here
} catch (\Delighted\RateLimitedException $e) {
    sleep($e->getRetryAfter());
    // Retry your request
}

Error handling and exceptions

Always be prepared:

try {
    // Your API calls here
} catch (\Delighted\RequestException $e) {
    echo "Oops! " . $e->getMessage();
}

Webhooks Integration

Setting up webhook endpoints

Listen for updates:

// In your webhook endpoint
$payload = file_get_contents('php://input');
$data = json_decode($payload, true);

// Process the webhook data

Processing webhook payloads

Do something cool with that data:

if ($data['event'] === 'survey_response.created') {
    // Handle new survey response
}

Best Practices

• Keep your API key secret (use environment variables, not hard-coded strings)
• Cache responses when possible to reduce API calls
• Use asynchronous processing for non-time-sensitive operations

Testing and Debugging

Unit test your integration:

public function testCreateSurveyResponse()
{
    $client = new Client('test-api-key');
    $response = $client->createSurveyResponse([
        'email' => '[email protected]',
        'score' => 9
    ]);
    $this->assertEquals(9, $response['score']);
}

Conclusion

And there you have it! You're now equipped to integrate Delighted's API into your PHP application like a pro. Remember, the key to great integrations is clean code and smart error handling. Now go forth and gather that valuable customer feedback!
