Transaction Errors

A transaction is initialised when a transactionId is passed to the triggerTransaction method on the client side SDK. Transaction is complete when the user logs in with the broker account & confirms the intent.

However, if intent is not completed, SDK shares error message & code to identify the cause of failure.

Here is a list of error messages that you can handle on your application and show relevant communication to the users:
