Extract

Step 7: open PP_PHP_NVP_Samples/constants.php and set up API Credentials Line no: 23, 33, 39.

Step 8: Run http://localhost/PP_PHP_NVP_Samples and click “ExpressCheckout - Sale” Link

Enter your personal account details as:

Pass: 268889126

[Note: Make sure you are signed in at paypal.developer.com For me Login Info: jbl.training@gmail.com / trainingcenter]

You will redirect to your site from paypal. By example, http://localhost/PP_PHP_NVP_Samples/ReviewOrder.php?currencyCodeType=USD&paymentType=Sale&token=EC-9FX13198W32250845&PayerID=JPQWEXV7JKM7C

Click “Buy” button

And finally http://localhost/PP_PHP_NVP_Samples/DoExpressCheckoutPayment.php page shows you Confirmation of your transaction

When come back from paypal (after successful transaction)it comes to

http://localhost/paypal/ReviewOrder.php?currencyCodeType=GBP&paymentType=sale&LastTakewayId=1&token=EC-7SL107200L902835S&PayerID=JPQWEXV7JKM7C

Here LastTakewayId is my variable added paypal/ReviewOrder.php page at $returnURL=urlencode($url.’/ReviewOrder.php?currencyCodeType=’.$currencyCodeType.’&paymentType=’.$paymentType.’&LastTakewayId=’.$_SESSION['LastTakewayId']);

TIPS:

1. Have a look Test Email from the left menu

2. Maximum time I login in an account at developer.paypal.com and use another account’s email and pass while transaction (during purchase)
