Fiskaly Logs
The Fiskaly Logs page displays a read-only record of every API request and response exchanged with the Fiskaly server during the fiscalization process. Use this page to audit and troubleshoot the Fiskaly integration—for example, when a transaction fails to upload, when an error message appears, or when you need to provide proof of submission to an audit partner.
To open the Fiskaly Logs page:
-
Go to Administration > Navigate > Fiscalization Setup.
-
On the Fiscalization Setup page, choose Fiskaly Logs from the ribbon.
-
The Fiskaly Logs page opens, showing the most recent API calls first. You can sort, filter, or search the list to find the log entry you need.

To view request and response payloads
-
On the Fiskaly Logs page, select the log entry you want to inspect.
-
Choose Get Payloads from the ribbon.
-
A dialog displays the raw JSON Request Payload sent to Fiskaly. Review the request data and choose OK.

A second dialog displays the raw JSON Response Payload returned by Fiskaly. This shows the server's reply, including any error codes or transaction IDs. Choose OK.
Note: The Fiskaly Logs page is read-only. Log entries are created automatically when API calls are made and cannot be deleted manually. To search for a specific transaction, filter by Store ID, POS Terminal No., or Fiskaly Transaction ID to narrow the results.
