Luna Game Library - Simple & Elegant Game Programming

Ok, IAP is now in. I got it down to these minimal routines:

//---------------------------------------------------------------------------
// In App Purchase
//---------------------------------------------------------------------------
procedure IAPSale(
  // processing
  aAPIKey    : PChar;
  aEvent     : TIAPEvent;

  // transaction
  aTransactionAmount: PChar;
  aTransactionDesc  : PChar;

  // credit card
  aCardCVVData      : PChar;
  aCardExpMonth     : Integer;
  aCardExpYear      : Integer;
  aCardNumber       : PChar;

  // customer
  aCustomerFirstName: PChar;
  aCustomerLastName : PChar;
  aCustomerAddress  : PChar;
  aCustomerCity     : PChar;
  aCustomerState    : PChar;
  aCustomerZip      : PChar;
  aCustomerCountry  : Pchar;
  aCustomerEmail    : PChar;
  aCustomerPhone    : PChar
  ); stdcall; external LUNA_DLL;
function  GetIAPResponseApproved: Boolean; stdcall; external LUNA_DLL;
function  GetIAPResponseApprovalCode: PChar; stdcall; external LUNA_DLL;
function  GetIAPResponseAVSResult: PChar; stdcall; external LUNA_DLL;
function  GetIAPResponseCode: PChar; stdcall; external LUNA_DLL;
function  GetIAPResponseCVVResult: PChar; stdcall; external LUNA_DLL;
function  GetIAPResponseInvoiceNumber: PChar; stdcall; external LUNA_DLL;
function  GetIAPResponseText: PChar; stdcall; external LUNA_DLL;
function  GetIAPResponseTransactionId: PChar; stdcall; external LUNA_DLL;

When you call IAPSale, the operation will be pushed into a background thread. When completed the aEvent routine will be called and you can then check the results with the GetIAPResponseXXX routines. If the transaction was approved GetIAPResponseApproved will be true and the transaction id (which is needed for refunds etc) will be returned. When testing, simply use your test API key you get from stripe. For a real purchase use the live key.

Since you also have database support, you can store your data on a remote database, on the local filesystem, encrypted, etc., as simple or elaborate as you wish.
