PayPal, Credit Card Payment API (means PayPal PHP merchant SDK) deals to process a credit card payment or DoDirect Payment on your website.

PayPal Credit Card Payment works in a few steps in the merchant’s website rather than going to the actual PayPal page and then logging in and returning back to the same.

The key thing is, using PayPal Credit Card, the payment process is done on your web page only. As the name also depicts it is a direct payment.

In our previous blog post, we have covered the PayPal Express Checkout for Digital Goods and Single Product using PayPal PHP SDK in which the payment process takes place in a different manner.

In this blog post, we are going to explain how we can use PayPal credit card payment in PHP for Direct payment.

 


 Watch the live demo or download code from the link given below

PayPal credit card and DoDirect payments in php

 


Project Integration

For configuration of PayPal PHP merchant SDK, add your account credentials in the configuration.php.

You can find this file in downloaded project “root folder”.

// Demo Signature Credential
"acct1.UserName" => "Demo-facilitator_api1.outlook.com",
"acct1.Password" => "PDRdd9FTWWU6FDBNKY",
"acct1.Signature" => "ANGx9dddfhOMduIxwcbkuUqPMh-9L15RAO6JJD8BDCZSxcx8nbBWeDOIbzW1",

Then you will be ready to run the project. You can also refer the install.txt file given in the download code folder.

 

Note: In demo we have used Sandbox and demo VISA card for testing, for making it live you have to edit configuration.php config array mode, sandbox to live as shown below.

 $config = array(
// values: 'sandbox' for testing
// 'live' for production
"mode" => "sandbox",
'log.LogEnabled' => true,
'log.FileName' => '../PayPal.log',
'log.LogLevel' => 'FINE'
);
