This package connects the non-official Transbank SDK into your Laravel Application.

• PHP >= 8.0
• Laravel 8.x

Check older releases for older Laravel versions.

Call composer and require it into your application.

composer require darkghosthunter/larabanker

This package mimics the Transbank SDK, so you should check the documentation of these services in Transbank Developer's site (in spanish).

• Webpay
• Webpay Mall
• Oneclick Mall

To start using Transbank services, you can use the included Webpay, WebpayMall and Oneclick facades and the redirect() method, which use minimum parameters and returns a ready-made GET redirect to Transbank.

use DarkGhostHunter\Larabanker\Facades\Webpay;

return Webpay::redirect('buy-order#1230', 1000);

Alternatively, you can still have total control to create transactions using the facades.

use DarkGhostHunter\Larabanker\Facades\Webpay;

$response = Webpay::create('buyOrder#1230', 1000, route('payment'));

return redirect()->away($response, 303);

Since API 1.2, Transbank services support GET redirects. There is no longer need to use views with Javascript redirection.

Redirects are made using default route names that centralizes the payment endpoint.

Laravel sets cookies as SameSite: lax by default. This means that the session is destroyed when a payment fails or is aborted. This happens because Transbank redirects using a POST method to your application without cookies, forcing Laravel to recreate a new empty session.

To avoid this, you should use the same path to receive the response from Transbank, but using a different controller for GET or POST. Larabanker conveniently uses one route name for each of Transbank services redirection points, which will be hit once the payment process ends.

You're free to change these Route names in the config file. Be sure to add your controllers for these routes to process the incoming response from Transbank.

In this example, we will disable the web middleware to avoid creating a new session, and return a view with a generic failure message.

use \DarkGhostHunter\Larabanker\Facades\Webpay;
use \Illuminate\Support\Facades\Route;

Route::get('transbank/webpay', function (Request $request) {
    $transaction = Webpay::commit($request->input('token_ws'));

    return view('payment.processed')->with('transaction', $transaction);
})->name('transbank.webpay');

Route::post('transaction/webpay, function (Request $request) {
    return view('payment.failed');
})->withoutMiddleware('web');

While Larabanker is made to use conveniently without setting too much, you can go deeper by publishing the configuration file:

php artisan vendor:publish --provider="DarkGhostHunter\Larabanker\ServiceProvider"

You will receive the larabanker.php config file with the following contents:

<?php

return [
    'environment' => env('TRANSBANK_ENV', 'integration'),
    'credentials' => [
        // ...
    ],
    'redirects' => [
        'webpay'       => 'transbank.webpay',
        'webpayMall'   => 'transbank.webpayMall',
        'oneclickMall' => 'transbank.oneclickMall',
    ],
    'protect' => env('TRANSBANK_PROTECT', false),
    'cache' => null,
    'cache_prefix' => env('TRANSBANK_PROTECT_PREFIX', 'transbank|token')
];

Don't worry, we will explain each important part one by one.

<?php

return [
    'environment' => env('TRANSBANK_ENV', 'integration'),
    'credentials' => [
        'webpay' => [
            'key' => env('WEBPAY_KEY'),
            'secret' => env('WEBPAY_SECRET'),
        ],
        'webpayMall' => [
            'key' => env('WEBPAY_MALL_KEY'),
            'secret' => env('WEBPAY_MALL_SECRET'),
        ],
        'oneclickMall' => [
            'key' => env('ONECLICK_MALL_KEY'),
            'secret' => env('ONECLICK_MALL_SECRET'),
        ],
    ],
];

By default, the package uses the integration environment, which makes fake transactions.

To use the production environment, which will make all transactions real, set the environment as production explicitly:

TRANSBANK_ENV=production

Additionally, you must add your Transbank credentials for your services, which will be issued directly to you, for the service(s) you have contracted. You can do it easily in your .env file.

WEBPAY_KEY=5000000001
WEBPAY_SECRET=dKVhq1WGt_XapIYirTXNyUKoWTDFfxaEV63-O5jcsdw

<?php

return [
    'redirects_base' => env('APP_URL'),
    'redirects' => [
        'webpay'       => 'transbank.webpay',
        'webpayMall'   => 'transbank.webpayMall',
        'oneclickMall' => 'transbank.oneclickMall',
    ],
];

Only when using the Webpay, WebpayMall and OneclickMall facades, you will be able to skip issuing the $returnUrl or $responseUrl values to the transaction creation, letting Larabanker to use the defaults issued in your config file.

use DarkGhostHunter\Larabanker\Facades\Webpay;

$response = Webpay::create('myOrder#16548', 1000);

return [
    'protect' => env('TRANSBANK_PROTECT', false),
    'cache' => null,
    'cache_prefix' => env('TRANSBANK_PROTECT_PREFIX', 'transbank|token')
];

Disabled by default, this package offers a brute-force attack protection middleware, larabank.protect, for return URL. These return URLs are your application endpoints that Transbank services will redirect the user to using a GET or POST request.

If it's disabled, the middleware won't verify the token.

use \Illuminate\Support\Facades\Route;
use \App\Http\Controllers\WebpayController;

Route::post('/transbank/webpay', [WebpayController::class, 'receivePayment'])
     ->middleware('larabank.protect');

It uses the cache to save the transaction token for 5 minutes, so if the token is no longer valid, the whole response is aborted. You can change the cache store and prefix with cache and cache_prefix, respectively.

This works for receiving the redirection from Transbank on Webpay, Webpay Mall and Oneclick Mall services.
