VerifyPaypal

VerifyPaypal is a PHP class to verify Paypal SDK payments, it verifies both credit card and paypal account transactions using the REST API and Adaptive Payments.

Known Issues

Paypal is currently having an issue with the Rest API in sandbox mode. Testing a credit card will result in an Invalid Resourse ID error. Hopefully this gets fixed soon.

Getting Started

• Start by cloning VerifyPaypal into your project:

git clone https://github.com/redfro/VerifyPaypal.git

• Next, provided you have composer installed, run the following command:

$ php composer.phar install

• This will install the library into a vendor folder. Now add the autoloader to your php files where applicable.

require 'VerifyPaypal/vendor/autoload.php';

• You need to use the PaypalPayment class, so add this directly under the autoloader.

use VerifyPaypal\Classes\PaypalPayment;

• Now update VerifyPaypalConfig.php (src/VerifyPaypal/Config/VerifyPaypalConfig.php) with your paypal information:

/*==========  Live Credentials  ==========*/

define('CLIENT_ID', '');
define('SECRET_KEY', '');
define('PAYPAL_ID', '');
define('PAYPAL_PW', '');
define('PAYPAL_SIG', '');
define('RECEIVER_EMAIL', '');

/*==========  Sandbox Credentials  ==========*/

define('CLIENT_ID_SANDBOX', '');
define('SECRET_KEY_SANDBOX', '');
define('PAYPAL_ID_SANDBOX', '');
define('PAYPAL_PW_SANDBOX', '');
define('PAYPAL_SIG_SANDBOX', '');
define('RECEIVER_EMAIL_SANDBOX', '');

• Create a new PaypalPayment() and set the environment to either "sandbox" or "live":

$payment = new PaypalPayment("sandbox");

• Pass the JSON sent from the Paypal SDK into verify():

$payment->verify($json);

The verify() method returns true if the payment is valid, false if not.

• You can check the status returned from Paypal using:

$payment->getStatus();

Example

require 'vendor/autoload.php';
use VerifyPaypal\Classes\PaypalPayment;

$payment = new PaypalPayment("sandbox");
$validPayment = $payment->verify($json);

if ($validPayment)
{
	// do something with valid payment
}

echo $payment->getStatus();  // check status message from paypal

Testing

You can test if VerifyPaypal is installed correctly by running the following command.

$ php tests/test.php

This should return "VerifyPaypal was installed correctly!".
