Installation

You can install the package via composer:

composer require mhmdahmd/hypersender

Configuration

Add your HyperSender API credentials to your config/services.php file:

'hypersender-api' => [
    'token' => env('HYPERSENDER_API_TOKEN'),
    'instance_id' => env('HYPERSENDER_INSTANCE_ID'),
    'api_base_uri' => env('HYPERSENDER_API_BASE_URI', 'https://app.hypersender.com/api/whatsapp/v1'),
],

Then add these environment variables to your .env file:

HYPERSENDER_API_TOKEN=your-api-token
HYPERSENDER_INSTANCE_ID=your-instance-id

Usage

To use this package, you need to create a notification class in your Laravel application. Here's an example:

<?php

namespace App\Notifications;

use Illuminate\Notifications\Notification;
use NotificationChannels\HyperSender\WhatsappMessage;

class WhatsappNotification extends Notification
{
    public function via($notifiable)
    {
        return ['whatsapp'];
    }

    public function toWhatsapp($notifiable)
    {
        return WhatsappMessage::create()
            ->to($notifiable->phone_number)
            ->content('Hello from HyperSender! This is a test message.');
    }
}

In your notifiable model (typically the User model), add the routeNotificationForWhatsapp method:

public function routeNotificationForWhatsapp()
{
    return $this->phone_number; // Return the user's phone number in international format (e.g., '201234567890')
}

Then, you can send a notification to a user:

$user->notify(new WhatsappNotification());

Available Methods

WhatsappMessage

The WhatsappMessage class provides a fluent interface for creating WhatsApp messages:

WhatsappMessage::create('Your message content')
    ->to('201234567890') // Phone number in international format
    ->line('Add a new line')
    ->escapedLine('Escaped content with *special* _characters_')
    ->lineIf($condition, 'Conditional line')
    ->safeMode() // Enable safe mode
    ->setLinkPreview(true) // Enable link previews
    ->token('custom-token') // Override default token
    ->sendWhen($condition) // Send only when condition is true
    ->onError(function ($error) {
        // Handle errors
    });

Message Formatting

• Basic Content: content('Your message')
• Add Lines: line('New line of text')
• Escaped Content: escapedLine('Text with *markdown* that will be escaped')
• Conditional Lines: lineIf($condition, 'This line appears only if condition is true')
• View Rendering: view('notifications.whatsapp.alert', ['data' => $data])

Message Options

• Safe Mode: safeMode() - Enables safe mode for message sending
• Link Preview: setLinkPreview(true) - Controls link preview behavior
• Custom Token: token('your-custom-token') - Override the default API token
• Conditional Sending: sendWhen($condition) - Only send when condition is true
• Custom Options: options(['custom_option' => 'value']) - Add custom options to the payload

Message Chunking

Large messages are automatically split into smaller chunks to comply with WhatsApp limits. The default chunk size is 4096 characters, but you can customize this in your configuration.

Exception Handling

You can handle exceptions using the onError method:

WhatsappMessage::create('Your message')
    ->to('201234567890')
    ->onError(function ($error) {
        Log::error('WhatsApp notification failed', $error);
        // Additional error handling logic
    });
