Step 3: Create Success File

Now we have to create success.php file for get Paypal transaction ID when payment will successfully then it will return here. that way we can identify payment is done or not so, create new file success.php.

success.php

$itemNo            = $_REQUEST['item_number'];
$itemTransaction   = $_REQUEST['tx']; // Paypal transaction ID
$itemPrice         = $_REQUEST['amt']; // Paypal received amount
$itemCurrency      = $_REQUEST['cc']; // Paypal received currency type
 
$price = '20.00';
$currency='USD';
 
if($itemPrice==$price && $itemCurrency==$currency)
{
    echo "Payment Successful";
}
else
{
    echo "Payment Failed";
}

Step 4: Create Cancel File

We also need to create cancel.php file because when paypal transaction will be cancel then it will redirect on this file.

success.php

echo "Payment Canceled";

Step 5: Paypal URL

It is complete for our sendbox with paypal integration but when you live this then you have to change $paypalId and $paypalUrl.
