Question

I'm currently integrating the paypal recurring payment process in my website. i used this code
function process()
{
include_once("config.php");
include_once("paypal.class.php");
if($_POST) //Post Data received from product list page.
{
//Mainly we need 4 variables from an item, Item Name, Item Price, Item Number and Item Quantity.
$ItemName = $_POST["itemname"]; //Item Name
$ItemPrice = $_POST["itemprice"]; //Item Price
$ItemNumber = $_POST["itemnumber"]; //Item Number
$ItemQty = $_POST["itemQty"]; // Item Quantity
$ItemTotalPrice = ($ItemPrice*$ItemQty); //(Item Price x Quantity = Total) Get total amount of product;
//Data to be sent to paypal
$padata = '&CURRENCYCODE='.urlencode($PayPalCurrencyCode).
'&PAYMENTACTION=Sale'.
'&ALLOWNOTE=1'.
'&PAYMENTREQUEST_0_CURRENCYCODE='.urlencode($PayPalCurrencyCode).
'&PAYMENTREQUEST_0_AMT='.urlencode($ItemTotalPrice).

//We need to execute the "SetExpressCheckOut" method to obtain paypal token
$paypal= new MyPayPal();
$httpParsedResponseAr = $paypal->PPHttpPost('SetExpressCheckout', $padata, $PayPalApiUsername, $PayPalApiPassword, $PayPalApiSignature, $PayPalMode);
//Respond according to message we receive from Paypal
if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"]))
{
// If successful set some session variable we need later when user is redirected back to page from paypal.
$_SESSION['itemprice'] = $ItemPrice;
$_SESSION['totalamount'] = $ItemTotalPrice;
$_SESSION['itemName'] = $ItemName;
$_SESSION['itemNo'] = $ItemNumber;
$_SESSION['itemQTY'] = $ItemQty;
if($PayPalMode=='sandbox')
{
$paypalmode = '.sandbox';
}
else
{
$paypalmode = '';
}
//Redirect user to PayPal store with Token received.

{
//we will be using these two variables to execute the "DoExpressCheckoutPayment"
//Note: we haven't received any payment yet.
$token = $_GET["token"];

Answer 1

Your request is missing a bunch of parameters which are required to create a recurring payment profile. Please refer to https://www.x.com/developers/paypal/documentation-tools/express-checkout/integration-guide/ECRecurringPayments.

Answer 2

I think the procedure is wrong: the second call should be a GetExpressCheckoutDetails to retrive the PAYERID in order to be able to do a CreateRecurringPaymentsProfile.
Just follow this tutorial step by step:
