Now how do i free the memory after use of this code???? Smilie
You can't, since you didn't save a copy of the pointer that you lost when you assigned SOME VALUE to CountryName.

One other point, in line 1, CountryName, I assume has some memory associated with it (since you've used it in the strlen()). The malloc is going to over write that pointer as well, so you'll have an additional storage leak there.

Business::PayPal::API::GetTransactionDetails - PayPal GetTransactionDetails API SYNOPSIS
use Business::PayPal::API::GetTransactionDetails; my $pp = new Business::PayPal::API::GetTransactionDetails ( ... ); or ## see Business::PayPal::API documentation for parameters use Business::PayPal::API qw(GetTransactionDetails); my $pp = new Business::PayPal::API( ... ); my %response = $pp->GetTransactionDetails( TransactionID => $transid, ); DESCRIPTION
Business::PayPal::API::GetTransactionDetails implements PayPal's GetTransactionDetails API using SOAP::Lite to make direct API calls to PayPal's SOAP API server. It also implements support for testing via PayPal's sandbox. Please see Business::PayPal::API for details on using the PayPal sandbox. GetTransactionDetails Implements PayPal's GetTransactionDetails API call. Supported parameters include: TransactionID as described in the PayPal "Web Services API Reference" document. Returns a hash containing the transaction details, including these fields: Business Receiver ReceiverID Payer PayerID PayerStatus Salutation FirstName MiddleName LastName PayerCountry PayerBusiness AddressOwner AddressStatus ADD_Name Street1 Street2 CityName StateOrProvince Country CountryName Phone PostalCode TransactionID ParentTransactionID ReceiptID TransactionType PaymentType PaymentDate GrossAmount FeeAmount SettleAmount TaxAmount ExchangeRate PaymentStatus PendingReason ReasonCode InvoiceID Custom Memo SalesTax PII_SaleTax PII_Name PII_Number PII_Quantity PII_Amount PII_Options PII_SubscriptionID PII_SubscriptionDate PII_EffectiveDate PII_RetryTime PII_Username PII_Password PII_Recurrences PII_reattempt PII_recurring PII_Amount PII_period PII_BuyerID PII_ClosingDate PII_multiItem As described in the API document.
