Status of transaction verification. By default, system will not run verification procedure on payment transactions events, i.e. system will not verify if sum of transaction is correct and this transaction was really done by user.
User could send a packet with transaction information to the metrics system servers emulating application, so unverified transactions metrics could include fraud transactions.
MyTracker could run verification on each mobile transaction by sending request to App Store and Google Play servers, however myTacker must have a key for payment verification — credentials.
If the key was added, MyTracker will verify each mobile transaction and both verified and unverified data will be available in metrics.
