📦 Installation

You can install the package via Composer:

composer require crunchzapp/crunchzapp-php-sdk

For Laravel Users

The package will be automatically discovered and registered in Laravel applications.

1. Publish the configuration file:

   php artisan vendor:publish --tag=crunchzapp-config

   This will create a config/crunchzapp.php file in your application that you can modify to configure the SDK.

2. Set your API Token:

   Add your CrunchzApp API token to your .env file. You can get your token from the CrunchzApp Dashboard.

   CRUNCHZAPP_TOKEN="your-api-token"

For Non-Laravel Users

If you are not using Laravel, you can instantiate the CrunchzApp class manually:

require 'vendor/autoload.php';

use CrunchzApp\CrunchzApp;

$token = 'your-api-token';
$crunchz = new CrunchzApp($token);

// You can now use the $crunchz object to interact with the API
$response = $crunchz->channel()->health();

🔧 Basic Usage

Sending Messages

use CrunchzApp\CrunchzApp;

// Initialize the service
$crunchz = app(CrunchzApp::class);

// Send a text message
$response = $crunchz->channel()
    ->contact('1234567890@c.us')
    ->text('Hello, World!')
    ->send();

// Send an image with caption
$response = $crunchz->channel()
    ->contact('1234567890@c.us')
    ->image('https://example.com/image.jpg', 'Check this out!')
    ->send();

// Send a location
$response = $crunchz->channel()
    ->contact('1234567890@c.us')
    ->location(-6.2088, 106.8456, 'Jakarta, Indonesia')
    ->send();

} catch (InvalidArgumentException $e) {
    // Handle validation errors (empty messages, invalid contact IDs, etc.)
    echo "Validation Error: " . $e->getMessage();
} catch (RuntimeException $e) {
    // Handle API errors (network issues, authentication, etc.)
    echo "API Error: " . $e->getMessage();
