    'default' => env('MOBILE_WALLET_PROVIDER', 'mtn'),

    // Default currency
    'currency' => env('MOBILE_WALLET_CURRENCY', 'ZMW'),

        'disbursement_subscription_key' => env('MTN_DISBURSEMENT_SUBSCRIPTION_KEY'),
        'environment' => env('MTN_ENVIRONMENT', 'sandbox'),
    ],

Usage

Backend Usage

You can use the facade to interact with the default provider:

use Mak8Tech\MobileWalletZm\Facades\MobileWallet;

// Request a payment
$result = MobileWallet::requestPayment(
    '0977123456',  // Phone number
    100.00,        // Amount
    'REF123',      // Reference (optional)
    'Payment for order #123' // Narration (optional)
);

// Check transaction status
$status = MobileWallet::checkTransactionStatus($transactionId);

To use a specific provider:

// Using a specific provider
$result = MobileWallet::provider('airtel')->requestPayment(
    '0977123456',
    100.00
);

Frontend Usage

The package includes a React component for payment forms. After publishing the assets, you can import and use the component:

import { PaymentForm } from "@/vendor/mobile-wallet-zm/components/payment-form";

function CheckoutPage() {
    const handleSuccess = (data) => {
        console.log("Payment initiated", data);
        // Handle successful payment initiation
    };

    const handleError = (error) => {
        console.error("Payment failed", error);
        // Handle payment error
    };

    return (
        <div>
            <h1>Checkout</h1>
            <PaymentForm
                amount={100.0}
                onSuccess={handleSuccess}
                onError={handleError}
                providers={[
                    { id: "mtn", name: "MTN Mobile Money" },
                    { id: "airtel", name: "Airtel Money" },
                    { id: "zamtel", name: "Zamtel Kwacha" },
                ]}
            />
        </div>
    );
}

Handling Webhooks

The package automatically registers routes to handle webhooks from all providers. Make sure your webhook URL is properly configured in your provider dashboard:

https://your-app.com/api/mobile-wallet/webhook/mtn
https://your-app.com/api/mobile-wallet/webhook/airtel
https://your-app.com/api/mobile-wallet/webhook/zamtel

You can also use the provider-agnostic endpoint:

https://your-app.com/api/mobile-wallet/webhook
