How can I get transactionID & receipt after purchasing successfully?

[leomyth330]

I've implemented MKStoreKit successfully and get notifications successfully after purchasing.
But I'm not able to get transactionID & receipt from parameter note.

[[NSNotificationCenter defaultCenter] addObserverForName:kMKStoreKitProductPurchasedNotification
      object:nil
       queue:[[NSOperationQueue alloc] init]
  usingBlock:^(NSNotification *note) {
      NSLog(@"Purchased/Subscribed to product with id: %@", [note object]);
  }];
