Hey @asuhan, I am not aware of a way to set the filename from the content-disposition header in your screenshot on the fly unfortunately, so I have converted this into a feature request for the time being.
As a workaround, you could manually rename the file like so if needed:
This example code is built upon this snippet provided by a helpful Stack Overflow user and further uses getBinaryData() and setBinaryData(binaryData) to manipulate the binary data received by the HTTP Request node.
Hope this helps!
