Usage

STK Push (Lipa Na M-Pesa Online)

use DrH\Mpesa\Facades\STK;

// Simple push
$result = STK::push(amount: 100, phone: '254712345678', ref: 'Order001', description: 'Payment for order');

// Fluent API
$result = STK::amount(100)
    ->from('254712345678')
    ->usingReference('Order001', 'Payment for order')
    ->push();

// Check STK transaction status
$status = STK::status($checkoutRequestId);

C2B (Customer to Business)

Register your validation and confirmation URLs with M-Pesa:

use DrH\Mpesa\Facades\Registrar;

Registrar::shortcode(174379)
    ->onConfirmation('https://example.com/payments/callbacks/c2b-confirmation')
    ->onValidation('https://example.com/payments/callbacks/c2b-validation')
    ->submit();

B2C (Business to Customer)

use DrH\Mpesa\Facades\B2C;

// Send payment
$result = B2C::send(number: '254712345678', amount: 500, remarks: 'Salary payment');

// Fluent API
$result = B2C::to('254712345678')
    ->amount(500)
    ->withRemarks('Salary payment')
    ->send();

// Check balance
$balance = B2C::balance();

// Check transaction status
$status = B2C::status($transactionId);

B2B (Business to Business)

use DrH\Mpesa\Facades\B2B;

// Send payment
$result = B2B::pay(
    type: 'BusinessPayBill',
    shortcode: '600000',
    amount: 1000,
    reference: 'INV001',
    phone: '254712345678'
);

// Check transaction status
$status = B2B::status($request);

Identity Verification

use DrH\Mpesa\Facades\Identity;

$result = Identity::validate('254712345678');

Events

The package dispatches events for payment lifecycle hooks. Listen for these in your EventServiceProvider or via Event::listen():

All events are in the DrH\Mpesa\Events namespace.

Artisan Commands

# Register C2B validation and confirmation URLs
php artisan mpesa:register_c2b_urls

# Check status of pending STK transactions
php artisan mpesa:query_stk_status

# Check status of pending B2C transactions
php artisan mpesa:b2c_transaction_status

# Check status of pending B2B transactions
php artisan mpesa:b2b_transaction_status

Callback Routes

The package automatically registers callback routes under /payments/callbacks/:

• POST /payments/callbacks/stk-callback - STK push callback
• POST /payments/callbacks/c2b-validation - C2B validation
• POST /payments/callbacks/c2b-confirmation - C2B confirmation
• POST /payments/callbacks/result/ - B2C/B2B result
• POST /payments/callbacks/timeout/ - B2C/B2B timeout

A pesa.cors middleware alias is available for CORS handling on callback routes.
