Step by Step Guide to Building a Better Proposals API Integration in PHP

Introduction

Hey there, fellow code wrangler! Ready to supercharge your proposal game? Let's dive into the world of Better Proposals API and see how we can integrate it into our PHP projects. This nifty API will help you streamline your proposal process, making your life easier and your clients happier. Let's get cracking!

Prerequisites

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

• PHP 7.4 or higher (come on, live a little on the edge!)
• cURL extension enabled (because who doesn't love a good curl?)
• A Better Proposals API key (your golden ticket to proposal paradise)

Setting Up the Environment

First things first, let's get our ducks in a row:

composer require guzzlehttp/guzzle

Now, let's keep that API key safe and sound:

define('BP_API_KEY', 'your_api_key_here');

Basic API Connection

Time to lay the groundwork. Let's create a base API class that'll do the heavy lifting:

use GuzzleHttp\Client;

class BetterProposalsAPI {
    private $client;
    private $baseUrl = 'https://api.betterproposals.io/v1/';

    public function __construct() {
        $this->client = new Client([
            'base_uri' => $this->baseUrl,
            'headers' => [
                'Authorization' => 'Bearer ' . BP_API_KEY,
                'Accept' => 'application/json',
            ],
        ]);
    }

    // More magic to come...
}

Core API Functions

Now, let's add some meat to those bones:

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

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

// Add update and delete methods similarly

Handling Responses

Let's make sure we're handling those responses like a pro:

private function handleResponse($response) {
    $data = json_decode($response->getBody(), true);
    if ($response->getStatusCode() !== 200) {
        throw new Exception($data['message'] ?? 'Unknown error occurred');
    }
    return $data;
}

Advanced Features

Feeling adventurous? Let's tackle webhooks and file uploads:

public function handleWebhook($payload) {
    // Process the webhook payload
    // Don't forget to verify the webhook signature!
}

public function uploadFile($filePath) {
    $response = $this->client->post('files', [
        'multipart' => [
            [
                'name'     => 'file',
                'contents' => fopen($filePath, 'r'),
            ],
        ],
    ]);
    return $this->handleResponse($response);
}

Optimizing the Integration

Let's make this baby purr:

use Symfony\Component\Cache\Adapter\FilesystemAdapter;

private $cache;

public function __construct() {
    // ... previous constructor code ...
    $this->cache = new FilesystemAdapter();
}

public function getProposals() {
    $cacheItem = $this->cache->getItem('proposals');
    if (!$cacheItem->isHit()) {
        $proposals = $this->fetchProposalsFromAPI();
        $cacheItem->set($proposals)->expiresAfter(3600);
        $this->cache->save($cacheItem);
    }
    return $cacheItem->get();
}

Testing and Debugging

Don't forget to test your code! Here's a quick example using PHPUnit:

use PHPUnit\Framework\TestCase;

class BetterProposalsAPITest extends TestCase {
    public function testGetProposals() {
        $api = new BetterProposalsAPI();
        $proposals = $api->getProposals();
        $this->assertIsArray($proposals);
        // Add more assertions as needed
    }
}

Security Considerations

Keep it locked down, folks:

// Use environment variables for API keys
$apiKey = getenv('BP_API_KEY');

// Log errors, but don't expose sensitive info
error_log('API Error: ' . $e->getMessage());

Conclusion

And there you have it! You've just built a rock-solid Better Proposals API integration in PHP. Remember, this is just the beginning – there's always room for improvement and customization. Keep exploring the API docs, stay curious, and happy coding!
