public function testPush() {

    // Resolve service object
    $push = MpesaPush::instance();
    
    $customerMsisdn = '<substitute valid mpesa-tz number>';
    $amount = 250;
    $txnId = str_random('20');
    
    $responseCode = $push->postRequest($customerMsisdn, $amount, $txnId);
    
    // Check for response code
    // Valid response codes
    //  '0' - Success (note: response code is string '0' not numeric 0)
    //  'Duplicate' - Duplicate transaction ID
    //   Others - fail
    
}
    

Handling callback

Out of the box, this package stores transactions in table mpesa_push_transactions, and updates their status on receiving callback.

However, you may need to do further actions on your app after receiving callback, by listening to event MpesaCallbackReceived::class fired at callback.

You need to implement your own event listener to listen for this event and do any additional steps after receiving callback.

The event has public attribute $transaction which contains the transaction parameters including status

// EventServiceProvider.php

protected $listen = [
    ...
    \Tumainimosha\MpesaPush\Events\MpesaCallbackReceived::class => [
        \App\Listeners\MpesaCallbackReceivedHandler::class,
    ],
];

// MpesaCallbackReceivedHandler.php

public function handle(MpesaCallbackReceived $event)
{
    $transaction = $event->transaction;
    
    // do your custom logic here
}

Customize config values at runtime

The service offers fluent setters to change config values at runtime if your use case requires.

Such a use case could be when you have multiple accounts on the same project, and you fetch your config values from DB.

// $account here could be a Model fetched from db with account attributes
$pushService = MpesaPush::instance();

$pushService->setUsername($account->username)
    ->setPassword($account->password)
    ->setBusinessName($account->business_name)
    ->setBusinessNumber($account->business_number)
    ->setCommand($account->command);
    
$pushService->postRequest($customerMsisdn, $amount, $txnId);
