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., _(*1)

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., _(*2)

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., _(*3)

• 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., _(*4)

$ php tests/test.php

This should return "VerifyPaypal was installed correctly!"., _(*5)
