# Nexmo / Laravel Notifications

Nexmo is now known as Vonage

Although Nexmo is [available in Laravel](https://laravel.com/docs/5.8/notifications#sms-notifications) as the default SMS provider, the next generation of Nexmo APIs will offer more communication channels. This package adds the ability to send notifications to WhatsApp, Facebook Messenger and Viber via Nexmo.

*Note that the [Messages API](https://developer.nexmo.com/messages/overview) that this package uses has not yet had its stable release so both the API and this library are subject to change*

## Usage

To use this package, run `composer require nexmo/laravel-notification`. Once it completes, you can implement the following methods on your notification:

* `toNexmoWhatsApp`
* `toNexmoFacebook`
* `toNexmoViberServiceMessage`
* `toNexmoSms`

See [examples/Notification/MerryChristmas.php](examples/Notification/MerryChristmas.php) for a complete example.

To send a notification, specify the channel you'd like to use:

```php
// To a user
$user->notify(new \App\Notifications\MerryChristmas());

// To any person
Notification::route(
'nexmo-whatsapp',
'YOUR_NUMBER'
)->notify(new \App\Notifications\MerryChristmas());
```

The available channels are:

* `nexmo-sms`
* `nexmo-whatsapp`
* `nexmo-facebook`
* `nexmo-viber_service_msg`

As each notification receives a `$notifiable` (usually a user) it can decide how best to route the information. In this case, it checks the `via_whatsapp` property on the user and sends via WhatsApp if it's true. Otherwise it falls back to email

```
public function via($notifiable)
{
return $notifiable->via_whatsapp ? ['nexmo-whatsapp'] : ['mail'];
}
```

### Message Types

Nexmo supports multiple message types, depending on the channel that you're sending to. The `Text` type is the safest if you want to deliver to all channels:

```
public function toNexmoWhatsApp($notifiable)
{
return (new \Nexmo\Notifications\Message\Text)
->content('This is a message being sent to WhatsApp');
}
```

### Caveats

For some channels you need to send a templated message before you can send a free text message due to spam control rules. Here's an example of how to use a preapproved template intended for two-factor authentication purposes:

```
public function toNexmoWhatsApp($notifiable)
{
return (new \Nexmo\Notifications\Message\Template)
->name("whatsapp:hsm:technology:nexmo:verify")
->parameters([
["default" => "Your Brand"],
["default" => "64873"],
["default" => "10"],
]);
}
```

If the recipient replies to your message, you can send them `Text` type messages without any issues

## Configuration

### Authentication

This notifications package is built on top of [nexmo/laravel](https://github.com/Nexmo/nexmo-laravel) and uses the Nexmo client from there.

For this to work, you need to set your application ID and path to your private key in the `.env` file:

```
NEXMO_APPLICATION_ID=my_application_id
NEXMO_PRIVATE_KEY=./private.key
```

### Setting the `from` address

You can set a `from `address via the `.env` file. This package will look for provider specific entries before falling back to `NEXMO_FROM`.

```
NEXMO_FROM_SMS=""
NEXMO_FROM_WHATSAPP=""
NEXMO_FROM_MESSENGER=""
NEXMO_FROM_VIBER_SERVICE_MSG=""
NEXMO_FROM="" # This is the default if any of the above aren't set
```

Alternatively, you can set a `from` address for a single notification by calling the `->from()` method on a message:

```php
public function toNexmoViberServiceMessage($notifiable)
{
return (new Text)->content('Merry Christmas Viber!')->from("YOUR_ID");
}
```
