Setting up your Whatsapp session

Set your venom session Venom Session and configure your Whatsapp Session:

# config/whatsapp-notification-channel/services.php

'whatsapp-bot-api' => [
        'whatsappSessionFieldName' => env('WHATSAPP_API_SESSION_FIELD_NAME', ''), //Session field name
        'whatsappSession' => env('WHATSAPP_API_SESSION', ''), // session value
        'base_uri' => env('WHATSAPP_API_BASE_URL', ''), //  Your venom base url api
        'mapMethods' => [ 
            'sendMessage' => 'sendText',
            'sendDocument' => 'sendFile',
        ], /* If you want to change the methods that will be called in the api, you can map them here, example: sendMessage will be replaced by the sendText method of the api */
    ],

Proxy or Bridge Support

You may not be able to send notifications if Whatsapp API is not accessible in your country, you can either set a proxy by following the instructions here or use a web bridge by setting the base_uri config above with the bridge uri.

You can set HTTPS_PROXY in your .env file.

Usage

You can now use the channel in your via() method inside the Notification class.

Text Notification

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

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

    public function toWhatsapp($notifiable)
    {
        $url = url('/invoice/' . $this->invoice->id);

        return WhatsappMessage::create()
            // Optional recipient user id.
            ->to($notifiable->whatsapp_number)
            // Markdown supported.
            ->content("Hello there!\nYour invoice has been *PAID*")

            // (Optional) Blade template for the content.
            // ->view('notification', ['url' => $url])
    }
}

Attach an Audio

public function toWhatsapp($notifiable)
{
    return WhatsappFile::create()
            ->to($notifiable->whatsapp_number) // Optional
            ->content('Audio') // Optional Caption
            ->audio('/path/to/audio.mp3');
}

Attach a Photo

public function toWhatsapp($notifiable)
{
    return WhatsappFile::create()
        ->to($notifiable->whatsapp_number) // Optional
        ->content('Awesome *bold* text')
        ->file('/storage/archive/6029014.jpg', 'photo'); // local photo

        // OR using a helper method with or without a remote file.
        // ->photo('https://file-examples-com.github.io/uploads/2017/10/file_example_JPG_1MB.jpg');
}

Attach a Document

public function toWhatsapp($notifiable)
{
    return WhatsappFile::create()
        ->to($notifiable->whatsapp_number) // Optional
        ->content('Did you know we can set a custom filename too?')
        ->document('https://file-examples-com.github.io/uploads/2017/10/file-sample_150kB.pdf', 'sample.pdf');
}

Attach a Location

public function toWhatsapp($notifiable)
{
    return WhatsappLocation::create()
        ->latitude('40.6892494')
        ->longitude('-74.0466891');
}

Attach a Video

public function toWhatsapp($notifiable)
{
    return WhatsappFile::create()
        ->content('Sample *video* notification!')
        ->video('https://file-examples-com.github.io/uploads/2017/04/file_example_MP4_480_1_5MG.mp4');
}

Attach a GIF File

public function toWhatsapp($notifiable)
{
    return WhatsappFile::create()
        ->content('Woot! We can send animated gif notifications too!')
        ->animation('https://sample-videos.com/gif/2.gif');

        // Or local file
        // ->animation('/path/to/some/animated.gif');
}

Routing a Message

You can either send the notification by providing with the whatapp number of the recipient to the to($whatsapp_number) method like shown in the previous examples or add a routeNotificationForWhatsapp() method in your notifiable model:

/**
 * Route notifications for the Whatsapp channel.
 *
 * @return int
 */
public function routeNotificationForWhatsapp()
{
    return $this->whatsapp_number;
}

Handling Response

You can make use of the notification events to handle the response from Whatsapp. On success, your event listener will receive a Message object with various fields as appropriate to the notification type.

For a complete list of response fields, please refer the Venom Whatsapp API's Message object docs.

On-Demand Notifications

Sometimes you may need to send a notification to someone who is not stored as a "user" of your application. Using the Notification::route method, you may specify ad-hoc notification routing information before sending the notification. For more details, you can check out the on-demand notifications docs.

use Illuminate\Support\Facades\Notification;

Notification::route('whatsapp', 'WHATSAPP_SESSION')
            ->notify(new InvoicePaid($invoice));

Sending to Multiple Recipients

Using the notification facade you can send a notification to multiple recipients at once.

If you're sending bulk notifications to multiple users, the Whatsapp API will not allow more than 30 messages per second or so. Consider spreading out notifications over large intervals of 8—12 hours for best results.

Also note that your bot will not be able to send more than 20 messages per minute to the same group.

If you go over the limit, you'll start getting 429 errors. For more details, refer Whatsapp Api FAQ.

use Illuminate\Support\Facades\Notification;

// Recipients can be an array of numbers or collection of notifiable entities.
Notification::send($recipients, new InvoicePaid());
