    Retryable Transaction Result

    A retryable transaction result occurs when the transaction can be retried. Examples:

    • Transaction canceled

    • Card read timeout

    • Wrong pin

    This result requires a user interaction, more precisely the tap on “Retry”. Hence, the autoClose flag will not affect the flow in this case.

    For not retryable ones, like a successful transaction or denied transaction, if autoClose value is true, the app will show the outcome animation and then close itself automatically. The caller app will receive the transaction data via deeplink.

    Since autoClose flag implies the buttons hiding and the sendTicket implies the visualization of “send ticket” button, the usage of both together will NOT be allowed. If sendTicket and autoClose are requested within the same session (both are true), the application will send the error “-21”.

    NB: The default sendTicket value is true for backward compatibility, so to use the autoClose feature it is mandatory to specify the value sendTicket false.

    Example request

    neximpos://payment?amount=1&callerTrxId=qwerty&sendTicket=false&urlTicket=true&callerName =Payment&email=name.surname%40domain.it&sms=3344556951&uri=demonexi%3A%2F%2Fpay ment&addInfo1=value1&addInfo2=value2&addInfo3=value3&addInfo4=value4&addInfo5=value5& autoClose=true
