Introduction

By using this plugin you can process or refund payments from PayPal in your Laravel application.

PayPal API Credentials

This package uses the classic paypal express checkout. Refer to this link on how to create API credentials:

https://developer.paypal.com/docs/classic/api/apiCredentials/#create-an-api-signature

Installation

• Use following command to install:

composer require obydul/larapal

• Laravel 5.5 uses package auto-discovery, so doesn't require you to manually add the ServiceProvider. If you don't use auto-discovery, add the service provider to your $providers array in config/app.php file like:

Obydul\LaraPal\LarapalServiceProvider::class

• Run the following command to publish configuration:

php artisan vendor:publish --provider="Obydul\LaraPal\LarapalServiceProvider"

Installation completed.

Configuration

• After installation, you need to set paypal credentialsin .env file.

LARAPAL_MODE=sandbox # sandbox or live
LARAPAL_API_USERNAME= # paypal api username
LARAPAL_API_PASSWORD= # paypal api password
LARAPAL_API_SIGNATURE= # paypal api signature

• Now optimize the app: php artisan optimize && php artisan config:clear.

Usage

Following are some ways through which you can access the LaraPal provider:

// Import the class namespaces first, before using it directly
use Obydul\LaraPal\Services\ExpressCheckout;

// Create object instance
$paypal = new ExpressCheckout();

// Redirect user to PayPal to obtain charging permissions
$paypal->doExpressCheckout(123.45, 'LaraPal Test Checkout', 'invoice_id', 'USD'); // single payment
$paypal->doExpressMultipleCheckout($items, 'invoice_id', 'USD', false, $customFields); // multiple items

// Perform payment, token and PayerID are being returned with GET response from PayPal
$paypal->doSinglePayment($_GET['token'], $_GET['PayerID']; // single payment
$paypal->doMultiplePayment($_GET['token'], $_GET['PayerID']; // multiple payment

// Perform refund based on transaction ID
$paypal->doRefund($transactionId, 'invoice_id', false, 0, 'USD', ''); // full refund
$paypal->doRefund($transactionId, 'invoice_id', true, 5.15, 'USD', ''); // partial refund

// Get transaction details 
$details = $paypal->getTransactionDetails($transactionId);

doExpressCheckout

// Structure - invoice ID must be unique
doExpressCheckout(AMOUNT, 'DESCRIPTION', 'INVOICE', 'CURRENCY', SHIPPING, CUSTOMFIELDS);
doExpressMultipleCheckout(ITEMS, 'INVOICE', 'CURRENCY', SHIPPING, CUSTOMFIELDS);

// Normal call
doExpressCheckout(123.45, 'LaraPal Test Checkout', 'invoice_id', 'USD');

// Pass custom fields to your order
$customFields = array(
    'identifier' => "Example.com/ID",
    'customerEmail' => "customer@email.com",
);

// Now do the express checkout. If you don't like to pass custom fields, then remove $customFields.
$paypal->doExpressCheckout(123.45, 'LaraPal Test Checkout', 'invoice_id', 'USD', false, $customFields);

// multiple items payment
$items = array(
    array(
        "name" => "Product 1",
        "price" => "12.25",
        "quantity" => "1",
        "product_id" => 111
    ),
    array(
        "name" => "Product 2",
        "price" => "25.50",
        "quantity" => "1",
        "product_id" => 112
    )
);

$paypal->doExpressMultipleCheckout($items, $invoice_id, 'USD', false, $customFields);

doRefund

// Structure
doExpressCheckout(TRANSACTION_ID, 'INVOICE_ID', 'IS_PARTIAL', PARTIAL_AMOUNT, CURRENCY, NOTE);

// Full refund
doRefund($transactionId, 'invoice_id', false, 0, 'USD', '')

// Partial refund
doRefund($transactionId, 'invoice_id', true, 12.25, 'USD', '') // you can pass note also

Example

After installing LaraPal, create routes and create a controller named 'PayPalController':

// Routes
Route::get('payment-status', 'PayPalController@paymentStatus')->name('payment-status');
Route::get('single-payment', 'PayPalController@singlePayment');
Route::get('multiple-payment', 'PayPalController@multipleItemsPayment');
Route::get('do-the-payment', 'PayPalController@doThePayment');
Route::get('refund-payment', 'PayPalController@doRefund');
Route::get('cancel-payment', 'PayPalController@cancelPayment');

// Controller
php artisan make:controller PayPalController

Now in your PayPalController add this: PayPalController.php

Now just visit the URL to make an action:

http://example.com/single-payment
http://example.com/multiple-payment
http://example.com/refund-payment

After successful payment, you will be redirected to http://example.com/payment-status and will see a message like: Success! Transaction ID: 9TR987531T2702301.
