Help & support
We've updated our CommBiz Automated Secure File Transfer service to improve connectivity and resiliency for our customers.
A CommBiz Automated service is still accessible via our two connectivity options:
We're asking customers to confirm the following by 30 April 2025:
For ongoing security and resilience of the SFTP service, we're phasing out support for prior versions of SFTP and ciphers from end of August 2025.
For continued connectivity, you'll need to ensure that your SFTP versions and ciphers are compatible with the listed ciphers below before this date.
Optional, however not required for the update to be completed.
Pilot mode
You can choose for CommBank to move the CommBiz Automated Service back into Pilot Mode for a short period of time. A CommBank Project Manager will assist you with testing in Pilot Mode.
Any files uploaded into the CommBiz/outbox during this phase of testing will be automatically re-routed to the CommBiz/inbox for collection.
Pilot Mode testing is to ensure that the SFTP client can connect, upload and download files appropriately. CommBiz Automated will not attempt to validate any files while on Pilot Mode.
Pilot Mode testing could take place at a quieter time of day when no payments are planned.
End-to-end testing in production mode
If your IT Team feel comfortable to do so, they can test in Production Mode once you have made the scripting changes.
In Production Mode all files uploaded into the CommBiz/outbox will be collected, validated and processed (if validation is successful) by CommBiz. Any files that do not pass validation will be unable to be imported for processing.
Note: You do not need to advise CommBank of testing in Production Mode.
CommBank doesn't have visibility of how customers connect to us or the configuration of their SFTP clients. We're requesting confirmation of your SFTP client versions and ciphers so that we can work closely with you to ensure upgrades are completed in time.
Our new SFTP platform supports characters outlined in the industry standard ISO8859-1. Using characters not in this standard may cause file validation issues which would prevent your payment file from processing.
For more information on ISO8859-1 character sets, refer to resources such as the ISO website and ASCII-Code for more information.
For security purposes, our new solution will require SFTP v3 and above. If you're already using SFTP V3 client or above, there's nothing for you to change.
To help us ensure the upgrade is progressing successfully and ready for Phase 2, please confirm your; CommBiz service ID, CommBiz service name, the version of SFTP software and ciphers you are using by emailing: paymentb2bsupport@cba.com.au
If you are using an earlier version of SFTP or unsupported ciphers, we would like to work with you to uplift to a compatible version by end of August 2025.
To help us ensure the upgrade is progressing successfully and ready for Phase 2, please confirm your; CommBiz service ID, CommBiz service name, the version of SFTP software and ciphers you are using by emailing: paymentb2bsupport@cba.com.au
Email us at paymentb2bsupport@cba.com.au to discuss any custom scripts or customisations that you are concerned may impact this SFTP upgrade.
No you will still have the same Logon ID and other existing CommBiz service details
No, current key pairings are still valid
There are no changes to file specifications.
However, we are asking customer to ensure the character sets within their files are compliant with the industry standard ISO8859-1.
There are also no changes to status reporting or reporting formats.
If you are using an older version of SFTP software, only the version of SFTP software will need to be upgraded.
If you use CommBiz Automated to send payment files, our recommendation is to test a low-value-live payment (ABA) file (e.g. $0.01) to your own account or a trusted beneficiary.
If testing payment file processing, we recommend you work with your IT Team (for full straight through processing) and your CommBiz Authorisers (for manual authorisation of payments) so they are aware of the testing and do not accidentally generate files or authorise transactions that your IT team did not want processed.
If you use CommBiz Automated for reporting purposes only, please test by confirming successful collection of report files.
