How do I access the magento log file using ONLY the web interface

We are getting orders from Magento that feeds into our Enfocus Switch computer.
I have an order that has given the error:

<?xml version="1.0"?>
<response>
  <message>Internal Error. Details are available in Magento log file. Report ID: webapi-65d79324a87f6</message>
 </response>

I do not have access to the underlying OS, only the Magento web interface.
I have been through the menus but don’t see how to access the log file.

Is it possible to view this logfile using only the web interface?
