Usage

use Apxcde\LaravelMpesaB2c\MpesaB2C;
use Apxcde\LaravelMpesaB2c\Models\MpesaB2CTransaction;

MpesaB2C::init([]); // Initialize the Mpesa B2C API

MpesaB2C::send($phone_number, $amount, 'BusinessPayment', $remarks, null, function($response) use ($amount, $phone_number) { 
    if (array_key_exists('errorCode', $response)) {
        return [
            'state' => 'Failed',
            'error_code' => $response['errorCode'],
            'error_message' => $response['errorMessage']
        ];
    }
    
    if($response["ResponseCode"] != 0) { 
        return [ 'state' => 'Failed' ];
    }
    
    // You can save the transaction to your database here
    // You can modify the table by publishing the migration file and adding values like phone_number, account_number, etc
    // Saving the transaction to the database is important because MPESA responds to the results url (value in the .env file).
    MpesaB2CTransaction::create([
        'originator_conversation_id' => $response["OriginatorConversationID"],
        'conversation_id' => $response["ConversationID"],
        'description' => $response["ResponseDescription"],
        'transaction_amount' => $amount,
        'transaction_id' => $transaction->id,
    ]);
    
    return [
        'state' => 'Pending',
        'mpesa_transaction' => $mpesa_transaction,
        'description' => "Request to send ".money($amount)." to ". $phone_number . " received successfully \n"
    ];
});

In the controller of your results url, you can get the transaction by originator_conversation_id. Controller should look like this:

use Apxcde\LaravelMpesaB2c\Models\MpesaB2CTransaction;
use Apxcde\LaravelMpesaB2c\MpesaB2C;

class MpesaController extends Controller
{
    public function resultsUrl(Request $request)
    {
        MpesaB2C::reconcile(function($request) {
            $Result = $request["Result"];
            $ResultCode = $Result["ResultCode"];
            $ResultDesc = $Result["ResultDesc"];
            $TransactionID = $Result["TransactionID"];
            $OriginatorConversationID = $Result["OriginatorConversationID"];
            
            $transaction = MpesaB2CTransaction::find($OriginatorConversationID);
            
            // Check if the transaction failed
            if($ResultCode != 0) {
                // Update the saved transaction
                $transaction->update([
                    'state' => 'Failed',
                    'description' => $ResultDesc,
                    'mpesa_transaction_id' => $TransactionID,
                ]);
                // Do something else here: Send an email, SMS, etc
                // Return so the function doesn't continue
                return null;
            }
            
            $ResultParameter = $Result["ResultParameters"]["ResultParameter"];
            $ReceiverPartyPublicName = $ResultParameter[config('mpesa-b2c.party_public_name')]["Value"];
            
            // Update the saved transaction because the B2C transaction was successful 
            $transaction->update([
                'state' => 'Accepted',
                'description' => $ResultDesc,
                'mpesa_transaction_id' => $TransactionID,
                'receiver_public_data' => $ReceiverPartyPublicName,
            ]);
            
            // You can do other things here: Send an email, SMS to the customer, etc
            // Also maybe update the customer's account in your database
        });
    }
}
