Separate Payment Integeration For Selected plan type using Drupal Form with Paypal API - forms

Question

I have used a normal class as an API and in that U am passing all the parameters to paypal and i am getting success.
Only thing i am missing is that amount is not being deducted from the sandbox account.
Where as if i pay amount for buying a product by using checkout with paypal the actual amount is being deducted in my sandbox account.
What could be the reason? Is there any other alternative way where i can able to use paypal to receive money through passed arguments in payment details form.
In the submit function of the drupal form i am calling like this.
$paypalDoDirect = new PaypalDoDirect();
// passing all parameters to $paypalDoDirect
$response= $paypalDoDirect->MakePayment();
I am getting transaction is successful and every parameters are getting passed sucessfully.
This is my class api-
class PaypalDoDirect
{
/**Declared all fields **/
function MakePayment()
{
$API_Endpoint = "https://api-3t.paypal.com/nvp";
if ("sandbox" === $this->environment || "beta-sandbox" === $this->environment) {
$API_Endpoint = "https://api-3t.$this->environment.paypal.com/nvp";
}
// Add request-specific fields to the request string.
$nvpStr = "&PAYMENTACTION=$this->paymentType&AMT=$this->amount&CREDITCARDTYPE=$this->cc_type&ACCT=$this->cc_number" .
"&EXPDATE=$this->expdate_month$this->expdate_year&CVV2=$this->cvv2_number&FIRSTNAME=$this->first_name&LASTNAME=$this->last_name&EMAIL=$this->email" .
"&STREET=$this->address1&CITY=$this->city&STATE=$this->state&ZIP=$this->zip&COUNTRYCODE=$this->country&CURRENCYCODE=$this->currencyID";
//$httpParsedResponseAr = PPHttpPost('DoDirectPayment', $nvpStr);
$methodName_ = 'DoDirectPayment';
$nvpStr_ = $nvpStr;
// Set the curl parameters.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
// Turn off the server and peer verification (TrustManager Concept).
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
// Set the API operation, version, and API signature in the request.
$nvpreq = "METHOD=$methodName_&VERSION=$this->version&PWD=$this->API_Password&USER=$this->API_UserName&SIGNATURE=$this->API_Signature$nvpStr_";
// Set the request as a POST FIELD for curl.
curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);
// Get response from the server.
$httpResponse = curl_exec($ch);
if (!$httpResponse) {
return ("$methodName_ failed: " . curl_error($ch) . '(' . curl_errno($ch) . ')');
}
// Extract the response details.
$httpResponseAr = explode("&", $httpResponse);
$httpParsedResponseAr = array();
foreach ($httpResponseAr as $i => $value) {
$tmpAr = explode("=", $value);
if (sizeof($tmpAr) > 1) {
$httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
}
}
if ((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
exit("Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.");
}
if ("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) {
return "success";
} else {
return (urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]));
}
}
}

Answer 1

Yes there is a paypal API module in drupal. It's a nice structured module to extend paypal IPN in some custom module.
If you use this module, IPN callback will be handled by this module & you can get notification of it by hook_paypal_api_ipn() at your instance. If you go though paypal documentation about handling payment with paypal & look into the module code, you will understand the mechanism to use it well. I will recommend you to use this module.
Though you can create your own module to handle paypal payment either express or forward users there. I have done it once with drupal instance long ago. You will have to send users or data(for express) at given URL for your account with some information & what ever happens in there(pass/fail/terminate), paypal will inform you at your mentioned callback URL of your instance. Receive the info & do work accordingly..

This might be what you looking for,
Paypal Direct pay not working
Exerpt:
The DoDirectPayment call charges credit cards directly; it does not deduct from a PayPal account - even if that card is attached to an existing PayPal account. Therefore it doesn't show up as a transaction in our 'buyer' PayPal account.
