Payment Flow

Prepare Payment Data

System prepares transaction data with customer and order information

app/Http/Controllers/Payment/SslcommerzController.php

public function pay(Request $request)
{
    if (Session::has('payment_type')) {
        if (Session::get('payment_type') == 'cart_payment') {
            $combined_order = CombinedOrder::findOrFail($request->session()->get('combined_order_id'));
            
            $post_data = array();
            $post_data['total_amount'] = $combined_order->grand_total;
            $post_data['currency'] = "BDT";
            $post_data['tran_id'] = substr(md5($request->session()->get('combined_order_id')), 0, 10);

            $post_data['value_a'] = $post_data['tran_id'];
            $post_data['value_b'] = $request->session()->get('combined_order_id');
            $post_data['value_c'] = $request->session()->get('payment_type');
        }
    }
}

Add Customer Information

Include customer details for payment processing

app/Http/Controllers/Payment/SslcommerzController.php

$user = Auth::user();
$post_data['cus_name'] = $user->name;
$post_data['cus_add1'] = $user->address;
$post_data['cus_city'] = $user->city;
$post_data['cus_postcode'] = $user->postal_code;
$post_data['cus_country'] = $user->country;
$post_data['cus_phone'] = $user->phone;
$post_data['cus_email'] = $user->email;

Configure Callback URLs

Set success, fail, and cancel URLs

app/Http/Controllers/Payment/SslcommerzController.php

$server_name = $request->root() . "/";
$post_data['success_url'] = $server_name . "sslcommerz/success";
$post_data['fail_url'] = $server_name . "sslcommerz/fail";
$post_data['cancel_url'] = $server_name . "sslcommerz/cancel";

Initiate Payment Session

Send request to SSLCommerz and redirect customer

app/Http/Controllers/Payment/SslcommerzController.php

$sslc = new SSLCommerz();

// false: Redirect to SSLCOMMERZ gateway
// true: Show all payment gateways on your page
$payment_options = $sslc->initiate($post_data, false);

Handle Success Callback

Process successful payment and complete order

app/Http/Controllers/Payment/SslcommerzController.php

public function success(Request $request)
{
    $sslc = new SSLCommerz();
    $tran_id = $request->value_a;
    $payment = json_encode($request->all());

    if (isset($request->value_c)) {
        if ($request->value_c == 'cart_payment') {
            return (new CheckoutController)->checkout_done($request->value_b, $payment);
        } elseif ($request->value_c == 'wallet_payment') {
            $data['amount'] = $request->value_b;
            $data['payment_method'] = 'sslcommerz';
            Auth::login(User::find($request->value_d));
            return (new WalletController)->wallet_payment_done($data, $payment);
        }
    }
}

Currency Support

SSLCommerz only supports BDT (Bangladeshi Taka)

$post_data['currency'] = "BDT";

Ensure your system default currency is set to BDT when using SSLCommerz.

Custom Values

SSLCommerz allows passing custom values through the payment flow:

$post_data['value_a'] = $post_data['tran_id'];       // Transaction ID
$post_data['value_b'] = $order_id;                   // Order ID or amount
$post_data['value_c'] = $payment_type;               // Payment type
$post_data['value_d'] = $user_id;                    // User ID (for wallet/packages)

These values are returned in the callback URL and help identify the transaction.

Payment Methods Supported

SSLCommerz supports various payment methods in Bangladesh:

Credit/Debit Cards: Visa, Mastercard, Amex
Mobile Banking: bKash, Rocket, Nagad, Upay
Internet Banking: All major Bangladeshi banks
Mobile Wallets: OK Wallet, mCash

Cart Payment

if (Session::get('payment_type') == 'cart_payment') {
    $combined_order = CombinedOrder::findOrFail($request->session()->get('combined_order_id'));
    $post_data['total_amount'] = $combined_order->grand_total;
    $post_data['currency'] = "BDT";
}

Wallet Payment

elseif (Session::get('payment_type') == 'wallet_payment') {
    $post_data['total_amount'] = $request->session()->get('payment_data')['amount'];
    $post_data['currency'] = "BDT";
    $post_data['value_d'] = Auth::user()->id;
}

Package Payments

elseif (Session::get('payment_type') == 'customer_package_payment') {
    $customer_package = CustomerPackage::findOrFail(Session::get('payment_data')['customer_package_id']);
    $post_data['total_amount'] = $customer_package->amount;
    $post_data['currency'] = "BDT";
}

Error Handling

Payment Failure

app/Http/Controllers/Payment/SslcommerzController.php

public function fail(Request $request)
{
    $request->session()->forget('order_id');
    $request->session()->forget('payment_data');
    flash(translate('Payment Failed'))->warning();
    return redirect()->route('home');
}

Payment Cancellation

app/Http/Controllers/Payment/SslcommerzController.php

public function cancel(Request $request)
{
    $request->session()->forget('order_id');
    $request->session()->forget('payment_data');
    flash(translate('Payment cancelled'))->error();
    return redirect()->route('home');
}

IPN (Instant Payment Notification)

SSLCommerz sends IPN for payment verification:

app/Http/Controllers/Payment/SslcommerzController.php

public function ipn(Request $request)
{
    if ($request->input('tran_id')) {
        $tran_id = $request->input('tran_id');
        
        $combined_order = CombinedOrder::findOrFail($request->session()->get('combined_order_id'));

        if ($order->payment_status == 'Pending') {
            $sslc = new SSLCommerz();
            $validation = $sslc->orderValidate($tran_id, $order->grand_total, 'BDT', $request->all());
            
            if ($validation == TRUE) {
                echo "Transaction is successfully Complete";
            } else {
                echo "validation Fail";
            }
        }
    }
}

Configure IPN URL in SSLCommerz merchant panel:

https://yourdomain.com/sslcommerz/ipn

Testing

Sandbox Environment

SSLCommerz provides sandbox environment for testing:

Use Sandbox Credentials

Request sandbox credentials from SSLCommerz support

Configure Sandbox Mode

Set sandbox mode in business settings or .env

Test Payments

Use provided test card numbers and mobile banking test credentials

Test Card Numbers

SSLCommerz provides test cards for sandbox:

Card Number: 4111 1111 1111 1111
Expiry: Any future date
CVV: Any 3 digits

Troubleshooting

Payment Initiation Failed

Cause: Invalid credentials or incorrect payloadSolution:

Verify Store ID and Store Password
Check all required fields are provided
Ensure customer information is complete
Verify callback URLs are accessible

Currency Error

Cause: Non-BDT currency usedSolution:

// Must use BDT
$post_data['currency'] = "BDT";

Callback Not Working

Cause: URL configuration issueSolution:

Ensure URLs use HTTPS in production
Check routes are properly registered
Verify .htaccess configuration
Test URLs are publicly accessible

Transaction ID Duplicate

Cause: Same transaction ID used twiceSolution:

// Generate unique transaction ID
$post_data['tran_id'] = substr(md5($order_id . time()), 0, 10);

User Re-authentication

For wallet and package payments, the system re-authenticates users:

if ($request->value_c == 'wallet_payment') {
    Auth::login(User::find($request->value_d));
    return (new WalletController)->wallet_payment_done($data, $payment);
}

This ensures the user session is maintained after payment redirect.
