Bluefin Secure File Transfer Protocol (SFTP)

When using the Account Updater tool, the merchant must supply a request file to Bluefin and once the update is complete, Bluefin will send back a response file containing either the updated data or an error message if the update could not go through.

These files are sent to Bluefin and received from Bluefin via the Bluefin Secure FTP (SFTP).

To use the Bluefin Secure FTP, the merchant must first obtain a login credential from Bluefin to use that tool.
The merchant will then access the tool using either an SFTP client with the hostname or via the CARDCONEX Secure File Transfer web tool at

SFTP client on the command line:


IN an OUT folders

Once logged into the CARDCONEX SFTP web tool or connected via an SFTP client, there will be an "AUP" folder in the "Folders" section or at the root.

Inside that folder there are two folders:

  • the IN folder is where the merchant can send the files to Bluefin.
  • the OUT folder is where the merchant will find the response files from Bluefin once the updates are completed.

In each one of these folders, there is a subdirectory for each PayConex account for which the merchant may use the Account Updater tool.


File Upload

The merchant must upload the request file in the "IN > XXXXXXXXXXXXX" folder corresponding to the account through which the merchant wishes to verify and update the Card Data designated in that file.



  • The files are only placed in the IN this folder temporarily. Bluefin's server will pick up the files from the IN folder and send them to the Account Updater Process, and once this happens the file will be automatically deleted from that folder; therefore, you will see the file you uploaded disappear from the "IN > XXXXXXXXXXXXX" folder shortly after having uploaded it. This is normal.
  • Once the file is transferred from the Bluefin Secure FTP to the AUP Process, the merchant may follow the status of the request file via the Batch Console page in PayConex.
  • Also, note that there is a delay of a few minutes before the status of a new request file is available on the Batch Console page.

Check the Status on the Batch Console Page

After a few minutes, the files you have uploaded will disappear from and appear in the Account Updater Batch Console page in PayConex. This is where you can view the status of your request file being processed. See the Batch Console section for more details.

Once your file has been processed, you should receive a CardConex Notification email saying that a new file is available for you and you will find a response file on

Get the Response File

The response file will be found in the "OUT > XXXXXXXXXXXXX" folder corresponding to the account that was used when sending the request file.

Simply click on the "Download" button, or use your SFTP client to download your file.

If the Account Updater Process was unable to process your request file, the response file will have the file extension ".ERR" and will contain an error message.

Once you have downloaded the response file, you must delete it from the Bluefin Secure FTP system.



If you do not download and/or do not delete the file from the Bluefin Secure FTP system, these files will automatically be purged after a certain number of days. You cannot use this system for long-term storage of these files.
