africastalking-laravel

This is an unofficial Laravel SDK for interacting with Africa's Talking APIs that takes advantage of native Laravel components such as

HTTP Client in place of Guzzle client
Service Container for a great dev experience
Notifications to allow you route notifications via Africastalking
Config
Collections
Among many others

Installation

You can install the package via composer:

composer require samuelmwangiw/africastalking-laravel

You can publish the config file with:

php artisan vendor:publish --tag="africastalking-config"

This is the contents of the published config file:

return [
    'username' => env('AFRICASTALKING_USERNAME', 'sandbox'),
    'api-key' => env('AFRICASTALKING_API_KEY'),
    'sms' => [
        'from' => env('AFRICASTALKING_FROM'),
    ],
    'payment' => [
        'product-name' => env('AFRICASTALKING_PAYMENT_PRODUCT'),
    ],
    'voice' => [
        'from' => env('AFRICASTALKING_VOICE_PHONE_NUMBER'),
    ]
];

You should configure the package by setting the env variables in your .env file.

Usage

Application Balance

use SamuelMwangiW\Africastalking\Facades\Africastalking;

/** @var \SamuelMwangiW\Africastalking\ValueObjects\Balance $account */
$account = Africastalking::application()->balance();

// Or using the global helper function
$account = africastalking()->application()->balance();

Bulk Messages

The most basic example to send out a message is

use SamuelMwangiW\Africastalking\Facades\Africastalking;

$response = Africastalking::sms('Hello mom!')
        ->to('+254712345678')
        ->send();

// Or using the global helper function
$response = africastalking()->sms("Hello Mom")
        ->to('+254712345678')
        ->send();

Other valid examples are

use SamuelMwangiW\Africastalking\Facades\Africastalking;

$response = Africastalking::sms('It is quality rather than quantity that matters. - Lucius Annaeus Seneca')
        ->message("We made it!") //overwrites any text previously set
        ->text("Look, am on the internet") //alias to message()
        ->as('MyBIZ') // optional: When the senderId is different from `config('africastalking.sms.from')`
        ->to(['+254712345678','+256706123567'])
        ->bulk() // optional: Messages are bulk by default
        ->enqueue() //used for Bulk SMS clients that would like to deliver as many messages to the API before waiting for an acknowledgement from the Telcos
        ->send()

// Or using the global helper function
$response = africastalking()->sms()
        ->message("Hello Mom") //overwrites any text previously set
        ->to('+254712345678')
        ->send();

The response is Collection of \SamuelMwangiW\Africastalking\ValueObjects\RecipientsApiResponse objects

Premium Messages

use SamuelMwangiW\Africastalking\Facades\Africastalking;

$response = Africastalking::sms('It is quality rather than quantity that matters. - Lucius Annaeus Seneca')
        ->as('90012') // optional: When the senderId is different from `config('africastalking.sms.from')`
        ->to(['+254712345678','+256706123567'])
        ->premium() // Required to designate messages as bulk
        ->bulkMode(false) // True to send premium messages in bulkMode and false to send as premium
        ->retry(2) //specifies the number of hours your subscription message should be retried in case it’s not delivered to the subscriber.
        ->keyword('keyword') // optional:
        ->linkId('message-link-id') // optional:
        ->send()

The response is Collection of \SamuelMwangiW\Africastalking\ValueObjects\RecipientsApiResponse objects

Airtime

The most basic example to disburse airtime is

use SamuelMwangiW\Africastalking\Facades\Africastalking;

$response = Africastalking::airtime()
        ->to('+254712345678','KES',100)
        ->send();

// Or using the global helper function
$response = africastalking()->airtime()
        ->to('+256706345678','UGX',100)
        ->send();

You may also pass an instance of AirtimeTransaction

use SamuelMwangiW\Africastalking\Facades\Africastalking;
use SamuelMwangiW\Africastalking\ValueObjects\AirtimeTransaction;
use SamuelMwangiW\Africastalking\ValueObjects\PhoneNumber;
use SamuelMwangiW\Africastalking\Enum\Currency;

$transaction = new AirtimeTransaction(PhoneNumber::make('+256769000000'),Currency::UGANDA,1000)

$response = Africastalking::airtime()
        ->to($transaction)
        ->send();

The Airtime class provides an add() that's basically an alias to the to() and since either of these methods can be fluently chained, it unlocks capabilities such as adding the recipients in a loop and sending once at the end

use App\Models\Clients;

$airtime = africastalking()->airtime();

Clients::query()->chunk(1000, function ($clients) use($airtime) {
    foreach ($clients as $client) {
        $airtime->add($client->phone,'TZS',3000);
    }
});
$results = $airtime->send();

USSD Response

This package allows to easily create USSD response by exposing a \SamuelMwangiW\Africastalking\Response\UssdResponse class that implements Laravel's Responsable contract.

To send a ussd response, simply return africastalking()->ussd() in your controller.

The ussd optionally takes 2 parameters and returns an instance of UssdResponse:

response - The response message to be displayed to the client
expectsInput - A boolean whether or not to prompt for user input. The default value is true

The UssdResponse class has the following methods that can be chained fluently

response - Receives the response message to be displayed to the client as an argument
expectsInput - Receives the expectsInput boolean to be displayed to the client as an argument. The default value is true
end - Is an alias expectsInput() but sets the boolean value false always

See below an example controller that makes of the UssdResponse and Ussd's HttpRequest:

<?php

namespace App\Http\Controllers;

use App\Models\Client;
use Illuminate\Support\Str;
use SamuelMwangiW\Africastalking\Http\Requests\UssdEventRequest;
use SamuelMwangiW\Africastalking\Http\Requests\UssdSessionRequest;

class UssdController extends Controller
{
    public function session(UssdSessionRequest $request)
    {
        if (!$request->userInput()) {
            return africastalking()->ussd('Kindly enter your account number');
        }

        $account = Client::query()
            ->whereAccountNo(
                Str::of($request->userInput())->afterLast('*')->toString()
            )->first();

        if ($account?->exists()) {
            return africastalking()
                ->ussd("Your account Balance is KES {$account->balance}")->end();
        }

        return africastalking()
            ->ussd("The account you entered does not exists.\n\nKindly enter a valid account number");
    }

    public function event(UssdEventRequest $request)
    {
       //Handle the USSD event here
       
        return response('OK');
    }
}

Payments (wip)

Mobile Checkout

africastalking()
    ->payment()
    ->mobileCheckout()
    ->to('+254720123123')
    ->amount(5000)
    ->currency('KES')
    ->send()

Wallet Balance

/** @var \SamuelMwangiW\Africastalking\ValueObjects\Balance $balance **/
$balance = africastalking()->wallet()->balance();

Stash top up

africastalking()
    ->stash()
    ->topup('TZS',100000);

//or fluently
africastalking()
    ->stash()
    ->amount(10000)
    ->currency('USD')
    ->product('My Product') //To override the product name in config
    ->topup(); //topup() has an alias named send() if you fancy

Voice Responses

This package provides an easy and intuitive voice response builder that allows any combination of the following:

Note that all params marked as optional in the documentation are also optional

<?php

return africastalking()->voice()
    ->say(message: '', playBeep: "false", voice: "en-US-Standard-C")
    ->play(url: 'https://example.com/audio.wav')
    ->getDigits(
        say: 'Please enter your account number followed by the hash sign',
        finishOnKey: '#',
        timeout: '30',
        callbackUrl: 'http://mycallbackURL.com',
    )->dial(
        phoneNumbers: ['+254711XXXYYY', '+25631XYYZZZZ', '[email protected]'],
        record: true,
        ringBackTone: 'http://mymediafile.com/playme.mp3',
        maxDuration: 5,
        sequential: false,
        callerId: '+254711XXXYYY',
    )->record(
        say: 'Please enter your account number followed by the hash sign',
        finishOnKey: '#',
        timeout: '30',
        maxLength: 10,
        playBeep: true,
        trimSilence: true
    )->redirect(
        url: 'http://www.myotherhandler.com/process.php',
    )->reject();

See example in a controller below:

<?php

namespace App\Http\Controllers\CallCenter;

use SamuelMwangiW\Africastalking\Http\Requests\VoiceCallRequest;

class HandleCallsController
{
    public function __invoke(VoiceCallRequest $request)
    {
        if ($request->input('isActive')){
            return africastalking()->voice()
                       ->say('Welcome to Unicorn bank.')
                       ->getDigits(
                           say:'Please enter your account Number followed by the # key',
                           finishOnKey: '#'
                       )
        }
        
        return response('OK');
    }
}

<?php

namespace App\Http\Controllers\CallCenter;

use SamuelMwangiW\Africastalking\Http\Requests\VoiceCallRequest;

class RecordCallsController
{
    public function __invoke(VoiceCallRequest $request)
    {
        if ($request->input('isActive')){
            return africastalking()->voice()
                       ->say('Our working hours are 9AM - 7PM, Monday to to Friday')
                       ->record(
                            say: 'Please leave a message after the tone.',
                            finishOnKey: '#',
                            playBeep: true,
                            maxLength: 10,
                            trimSilence: true,
                       );
        }
        
        return response('OK');
    }
}

<?php

namespace App\Http\Controllers\CallCenter;

use SamuelMwangiW\Africastalking\Http\Requests\VoiceCallRequest;

class RejectCallsController
{
    public function __invoke(VoiceCallRequest $request)
    {
        if ($request->input('isActive')){
            return africastalking()->voice()
                       ->say('Our working hours are 9AM - 7PM, Monday to to Friday')
                       ->reject();
        }
        
        return response('OK');
    }
}

<?php

namespace App\Http\Controllers\CallCenter;

use App\Models\Doctor;
use SamuelMwangiW\Africastalking\Http\Requests\VoiceCallRequest;

class ForwardCallsController
{
    public function __invoke(VoiceCallRequest $request)
    {
        if ($request->input('isActive')){
            $doctor = Doctor::query()->onDuty()->first();
            
            return africastalking()->voice()
                       ->dial(
                            phoneNumbers: [$doctor->number],
                            record: true,
                            ringBackTone: "https://example.com/marketing-tone.wave"
                       );
        }
        
        return response('OK');
    }
}

Synthesized Speech Attributes.

The <Say /> action supports the use of Speech Synthesis Markup Language(SSML).

To respond with Synthesized Speech, pass a callback say() above as the first parameter that receives an instance of SynthesisedSpeech object

<?php

namespace App\Http\Controllers\CallCenter;

use SamuelMwangiW\Africastalking\Http\Requests\VoiceCallRequest;
use SamuelMwangiW\Africastalking\ValueObjects\Voice\SynthesisedSpeech;

class HandleCallsController
{
    public function __invoke(VoiceCallRequest $request)
    {
        if ($request->input('isActive')){
            return africastalking()->voice()
                       ->say(
                         fn(SynthesisedSpeech $speech) => $speech
                                 ->say('Welcome to Wasafi. Your airtime balance is')
                                 ->sayAsCurrency('$1000','en-US')
                                 ->say(' and expires on ')
                                 ->sayAsDate('20420420')
                                 ->say(' at ')
                                 ->sayAsTime('04:42PM')
                                 ->pause('69ms')
                                 ->say('For assistance Call our customer service team on ')
                                 ->sayAsTelephone('0800694269')
                                 ->bleep('Thank you for choosing us 😜')
                       )
        }
        
        return response('OK');
    }
}

Note You can only have a single <Say /> within an XML response

Making Calls

// Most basic call
africastalking()->voice()
    ->call('+254720123123')
    ->done();

// Call a list of users
africastalking()->voice()
    ->call(['+254720123123','+254731234567'])
    ->done();

// override the callerId
africastalking()->voice()
    ->call('+254720123123')
    ->as('+254711082999')
    ->done();

// Set the call Request Id
africastalking()->voice()
    ->call('+254720123123')
    ->requestId('id_12345')
    ->done();

// You can also use send if like that better
africastalking()->voice()
    ->call('+254720123123')
    ->send();

WebRTC

<?php

namespace App\Http\Controllers\Voice;

class WebRtcTokenController {
    public function __invoke()
    {
        $clientName = auth()->user()?->name ?? 'Browser';
        
        $token = africastalking()
            ->voice()
            ->webrtc()
            ->for($clientName)
            ->token();
        
        return [
            'token' => $token->token,
            'clientName' => $token->clientName,
            'expire' => $token->lifeTimeSec,
        ];
    }
}

HTTP Requests

The package ships with the following Laravel Requests that you can inject into your application controllers:

\SamuelMwangiW\Africastalking\Http\Requests\AirtimeStatusRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\AirtimeValidationRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\BulkSmsOptOutRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\IncomingMessageRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\MessageDeliveryRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\MobileC2BValidationRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\PaymentNotificationRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\SubscriptionRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\UssdEventRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\UssdSessionRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\VoiceCallRequest::class;
\SamuelMwangiW\Africastalking\Http\Requests\VoiceEventRequest::class;

In addition to exposing the post params in a nice FormRequest object, these classes also include nice helper methods where applicable e.g.

id() to retrieve the unique ATPid associated with every request
phone() to retrieve the client's phone number
userInput() to retrieve ussd user input
status() to get transaction / request final status
deliveryFailed() returns a boolean true if sms or airtime delivery failed and false otherwise
among many others

Example for a Message Delivery callback action Controller

<?php

namespace App\Http\Controllers\Messaging;

use App\Models\Message;
use SamuelMwangiW\Africastalking\Http\Requests\MessageDeliveryRequest;

class MessageDeliveredController{
    public function __invoke(MessageDeliveryRequest $request)
    {
        $message = Message::query()
                            ->where(['transaction_id'=>$request->id()])
                            ->firstOrFail();
                            
        $message->update([
            'delivered_at'=>now(),
            'status'=>$request->status(),
        ]);
        
        return response('OK');
    }
}

Notification

The package ships with a Channel to allow for easily routing of notifications via Africastalking SMS.

To route a notification via Africastalking, return SamuelMwangiW\Africastalking\Notifications\AfricastalkingChannel in your notifications via method and the text message to be sent in the toAfricastalking method

<?php

namespace App\Notifications;

use Illuminate\Notifications\Notification;
use SamuelMwangiW\Africastalking\Facades\Africastalking;
use SamuelMwangiW\Africastalking\Notifications\AfricastalkingChannel;

class WelcomeNotification extends Notification
{
    public function via($notifiable)
    {
        return [AfricastalkingChannel::class];
    }

    public function toAfricastalking($notifiable)
    {
        return "Hi {$notifiable->name}. Your account at Unicorn Bank has been created. Hope you enjoy the service";
    }
}

Also ensure that the notifiable model implements SamuelMwangiW\Africastalking\Contracts\ReceivesSmsMessages and that the model's routeNotificationForAfricastalking() returns the phone number to receive the message

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Notifications\Notifiable;
use Illuminate\Notifications\Notification;
use SamuelMwangiW\Africastalking\Contracts\ReceivesSmsMessages;

class User extends Model implements ReceivesSmsMessages
{
    protected $fillable = ['email','name','phone'];

    public function routeNotificationForAfricastalking(Notification $notification): string
    {
        return $this->phone;
    }
}
