$sections = [
    [
        'title' => 'Category 1',
        'rows' => [
            [
                'id' => 'row1',

Media Management

Upload Media

$response = Whatsapp::uploadMedia('/path/to/image.jpg', 'image');
$mediaId = $response['id'];

// Use the media ID to send the image
Whatsapp::sendMediaMessage('1234567890', $mediaId, 'image', 'Uploaded image');

Download Media

$filePath = Whatsapp::downloadMedia('media_id_123');
// File is saved to storage/app/whatsapp-media/media_id_123.jpg

Multi-tenant Support

Configure multiple WhatsApp Business accounts:

// In config/whatsapp.php
'tenants' => [
    'company1' => [
        'phone_number_id' => 'phone_number_1',
        'access_token' => 'access_token_1'

    ]
]

Use tenant-specific configuration:

// Send message using specific tenant
Whatsapp::sendTextMessage('1234567890', 'Hello!', 'company1');

Webhook Handling

Event Listeners

The package dispatches several events that you can listen to:

// In your EventServiceProvider
protected $listen = [
    \Crenspire\Whatsapp\Events\MessageSent::class => [
        // Your listener
    ],
    \Crenspire\Whatsapp\Events\MessageDelivered::class => [
        // Your listener
    ],
    \Crenspire\Whatsapp\Events\MessageRead::class => [
        // Your listener
    ],
    \Crenspire\Whatsapp\Events\MessageReceived::class => [
        // Your listener
    ],
    \Crenspire\Whatsapp\Events\MessageFailed::class => [
        // Your listener
    ],
];

Example Event Listener

<?php

namespace App\Listeners;

use Crenspire\Whatsapp\Events\MessageReceived;
use Illuminate\Contracts\Queue\ShouldQueue;

class HandleIncomingMessage implements ShouldQueue
{
    public function handle(MessageReceived $event)
    {
        // Handle incoming message
        $messageId = $event->messageId;
        $from = $event->from;
        $message = $event->message;
        $timestamp = $event->timestamp;
        
        // Your logic here
    }
}

Error Handling

The package throws WhatsappException for various error conditions:

use Crenspire\Whatsapp\Exceptions\WhatsappException;

try {
    Whatsapp::sendTextMessage('1234567890', 'Hello!');
} catch (WhatsappException $e) {
    // Handle WhatsApp API errors
    logger('WhatsApp error: ' . $e->getMessage());
}

Rate Limiting

The package includes built-in rate limiting to respect WhatsApp API limits:

// Configure rate limit in config/whatsapp.php
'rate_limit' => 30, // messages per minute

Logging

Enable debug logging:

// In config/whatsapp.php
'debug' => true,

Or set in your .env:

WHATSAPP_DEBUG=true

Testing

Run the test suite:

composer test

The package includes comprehensive tests covering all functionality.

Security

Webhook Verification

The package automatically verifies webhook signatures when WHATSAPP_WEBHOOK_SECRET is configured:

WHATSAPP_WEBHOOK_SECRET=your_webhook_secret

Phone Number Validation

All phone numbers are validated before sending messages to ensure they meet WhatsApp's requirements.

🔧 Custom Headers Support

The package now supports custom headers for all API requests, allowing you to add authentication, tracking, or other custom headers:

Basic Usage

// Using custom headers with individual requests
$customHeaders = [
    'X-Request-ID' => 'req_12345',
    'X-Client-Version' => '2.0.0',
    'X-Custom-Auth' => 'custom_token'
];

Whatsapp::sendTextMessage('+1234567890', 'Hello!', null, $customHeaders);

// Using custom headers with media upload
Whatsapp::uploadMedia('/path/to/file.jpg', 'image', null, $customHeaders);

// Using custom headers with media download
$filePath = Whatsapp::downloadMedia('media_id_123', null, $customHeaders);

Multi-tenant Headers

Configure per-tenant headers in your configuration:

// config/whatsapp.php
'tenants' => [
    'tenant1' => [
        'phone_number_id' => '123456789',
        'access_token' => 'token1',
        'headers' => [
            'X-Tenant-ID' => 'tenant1',
            'X-API-Version' => 'v2.0',
            'X-Custom-Header' => 'tenant1-value'
        ]
    ],
    'tenant2' => [
        'phone_number_id' => '987654321',
        'access_token' => 'token2',
        'headers' => [
            'X-Tenant-ID' => 'tenant2',
            'X-API-Version' => 'v1.5'
        ]
    ]
]

Default Headers

Set default headers for all requests:

// config/whatsapp.php
'default_headers' => [
    'Content-Type' => 'application/json',
    'Accept' => 'application/json',
    'User-Agent' => 'Laravel-WhatsApp-Package/1.0.0',
    'X-Client-Name' => 'MyApp',
    'X-Client-Version' => '1.0.0'
],

Header Priority

Headers are merged in the following order (later overrides earlier):

1. Default headers from configuration
2. Tenant-specific headers
3. Custom headers passed to individual methods
