The different types of errors that can occur during the workflow are:
-
Session time-out: an online session would be automatically terminated after a fixed period of time unless the customer is re-authenticated for the existing session to be maintained. This prevents the debtor from keeping an internet banking session alive indefinitely.
-
Creditor’s global configuration information is not complete: In this case the creditor and WL must check the creditor’s parameters.
-
Sign Session parameters for initializations are not complete: In this case the web service response will inform the creditor. The creditor has to initialize a new web service call with all the mandatory information.
-
Debtor Bank account is invalid: The debtor is informed of the mistake and has to fill a new bank account.
-
The debtor aborts the operation of signature: In this case, the session would be aborted. The mandate is not archived if the signature process did not end properly.
