Create callback functions to handle Fondy’s response. This includes updating the transaction status in your database and providing feedback to users.

// app/Http/Controllers/FondyController.php

namespace App\Http\Controllers;

use App\Models\Payment;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Http;

class FondyController extends Controller
{
    public function checkout(Request $request)
    {
        $order_id = 'your_unique_order_id'; // Generate a unique order ID
        $amount = 100.00; // Example amount in USD

        // Create a record in the payments table
        $payment = Payment::create([
            'order_id' => $order_id,
            'amount' => $amount,
        ]);

        $response = Http::post('https://api.fondy.eu/api/checkout/url', [
            'order_id' => $order_id,
            'currency' => 'USD',
            'amount' => $amount * 100, // Amount in cents
            'order_desc' => 'Payment for Order #' . $order_id,
            'response_url' => route('fondy.callback'), // Callback URL
            // Include other required parameters as per Fondy API documentation
        ]);

        $form = $response->json('response.checkout_url');

        return view('payments.checkout', compact('form'));
    }

    public function callback(Request $request)
    {
        // Handle Fondy callback, update payment status, etc.
    }
}

// app/Http/Controllers/FondyController.php

use App\Models\Payment;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Log;

class FondyController extends Controller
{
    // ... (other methods)

    public function callback(Request $request)
    {
        // Verify the callback request (check Fondy API documentation for security measures)

        // Example: Log the callback data
        Log::info('Fondy Callback Data: ' . json_encode($request->all()));

        // Extract relevant information from the callback
        $order_id = $request->input('order_id');
        $status = $request->input('order_status');
        $amount = $request->input('amount');

        // Find the corresponding payment record in the database
        $payment = Payment::where('order_id', $order_id)->first();

        if (!$payment) {
            // Handle case where payment record is not found
            Log::error('Payment record not found for order ID: ' . $order_id);
            return response()->json(['status' => 'error', 'message' => 'Invalid order ID'], 400);
        }

        // Compare the received amount with the stored amount
        if ($amount != $payment->amount * 100) {
            // Handle amount mismatch
            Log::error('Amount mismatch for order ID: ' . $order_id);
            return response()->json(['status' => 'error', 'message' => 'Invalid amount'], 400);
        }

        // Update payment status based on Fondy response
        if ($status == 'approved') {
            // Payment successful
            $payment->update(['status' => 'paid']);
            Log::info('Payment successful for order ID: ' . $order_id);
        } else {
            // Payment failed or other status
            $payment->update(['status' => 'failed']);
            Log::info('Payment failed for order ID: ' . $order_id);
        }

        // Respond to Fondy with a success message
        return response()->json(['status' => 'success']);
    }
}

In this example, the callback method verifies the callback data, extracts relevant information, finds the corresponding payment record in the database, and updates the payment status based on Fondy’s response. Adjust the logic based on Fondy’s API documentation and the specific requirements of your application. The key is to handle different scenarios, log relevant information, and respond appropriately to Fondy.

Model Configuration

5.1 Database Schema

Define the database schema for storing Fondy transaction details. This ensures a structured and organized approach to data management.

5.2 Creating the Model

Generate a model to interact with the database. This model will handle the insertion and retrieval of transaction data, ensuring data integrity.

Update the migration file to define the schema for the “payments” table:

// database/migrations/xxxx_xx_xx_create_payments_table.php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreatePaymentsTable extends Migration
{
    public function up()
    {
        Schema::create('payments', function (Blueprint $table) {
            $table->id();
            $table->string('order_id')->unique();
            $table->decimal('amount', 8, 2);
            $table->string('status')->default('pending');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('payments');
    }
}

Database Table Setup

6.1 Migration for Fondy Transactions

Create a migration to set up the database table for storing Fondy transactions. Run the migration to apply the changes to your database.

Run the migration:

6.2 Seeding Initial Data

Seed the database with initial data to facilitate testing. This step ensures a smooth testing environment for your Laravel Fondy Integration.

1. Create a seeder class:

This will create a seeder file in the database/seeders directory.

2. Update the seeder file:

Edit the seeder file to insert some initial data into the fondy_transactions table.

// database/seeders/FondyTransactionsSeeder.php

use Illuminate\Database\Seeder;
use App\Models\FondyTransaction;

class FondyTransactionsSeeder extends Seeder
{
    public function run()
    {
        FondyTransaction::create([
            'order_id' => 'test_order_1',
            'status' => 'success',
            'amount' => 50.00,
        ]);

        FondyTransaction::create([
            'order_id' => 'test_order_2',
            'status' => 'pending',
            'amount' => 75.00,
        ]);

        // Add more seed data as needed
    }
}

3. Run the seeder:

This will insert the specified data into the fondy_transactions table.

Now, you have a migration that sets up the database table for Fondy transactions, and you’ve seeded the database with initial data for testing purposes. Adjust the migration and seeder according to your application’s needs.

Defining Routes

7.1 Setting Up Web Routes

Define web routes in your Laravel application to direct incoming requests to the appropriate controller methods. This establishes the routing structure for Fondy transactions.

7.2 Handling Callback Routes

Configure routes specifically for Fondy callbacks. These routes will be invoked by Fondy to communicate the transaction status back to your application.

// routes/web.php

use App\Http\Controllers\FondyController;

Route::get('/checkout', [FondyController::class, 'checkout']);
Route::post('/callback', [FondyController::class, 'callback'])->name('fondy.callback');

Creating Views

8.1 Designing Payment Forms

Craft visually appealing payment forms that users interact with during the checkout process. Ensure a user-friendly design for a seamless payment experience.

8.2 Customizing Success and Failure Views

Create custom views to display success and failure messages. These views will be shown to users upon completing a transaction, enhancing the overall user experience.

<!-- resources/views/payments/checkout.blade.php -->

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Checkout</title>
</head>
<body>

    <!-- Display your checkout form here -->
    {!! $form !!}

</body>
</html>

Remember to customize the code according to your actual application requirements and replace placeholder values with your real Fondy credentials. Additionally, handle the Fondy callback in the callback method in the controller to update the payment status in your database.
