    \brief Contains information about an in-app transaction.

    Transaction contains information about a transaction in the external app store and is
    usually provided as a result of calling \l{QtPurchasing::Product::purchase()}{purchase()}
    on a product. When the purchase flow has ended, whether it's successful or not, either the
    product's \l{QtPurchasing::Product::onPurchaseSucceeded}{onPurchaseSucceeded} or
    \l{QtPurchasing::Product::onPurchaseFailed}{onPurchaseFailed} handler will be called
    with a transaction object as argument.

    Transaction cannot be created directly in QML, but is only provided as an argument to
    the purchase handlers in the products.

/*!
  \class QInAppTransaction
  \inmodule QtPurchasing
  \brief Contains information about a transaction in the external app store.

  QInAppTransaction contains information about a transaction in the external app store and is
  usually provided as a result of calling QInAppProduct::purchase(). When the purchase flow has
  been completed by the user (confirming the purchase, for instance by entering their password),
  the QInAppStore instance containing the product will emit a QInAppStore::transactionReady()
  signal with data about the transaction.

  The status() provides information on whether the transaction was successful or not. If it was
  successful, then the application should take appropriate action. When the necessary action has
  been performed, finalize() should be called. The finalize() function should be called regardless
  of the status of the transaction.

  It is important that the application stores the purchase information before calling finalize().
  If a transaction is not finalized (for example because the application was interrupted before
  it had a chance to save the information), then the transaction will be emitted again the next
  time the product is registered by QInAppStore::registerProduct().

  Transactions can also be emitted after calling QInAppStore::restorePurchases(), at which point
  a new transaction will be emitted for each previously purchased unlockable product with the
  status of PurchaseRestored.

  \note Since transactions may under certain circumstances be emitted for the same transaction
  several times, the application should always check if the transaction has been registered
  before. Do not expect each transaction to be unique.
