The easiest way to determine the base URL for a given
FTD device is to try out a GET method in the API Explorer, and
simply delete the object part of the URL from the result.
For example, you can do a GET /object/networks, and see something
similar to the following in the returned output under Request URL:
The server name part of the URL is
the hostname or IP address of the
FTD device, and will be different for your device in place of
“ftd.example.com.” In this example, you delete /object/networks from the path
to get the base URL:
All resource calls use this URL as the base for the request URL.
The "v" element in the URL is the API version, and this will typically change with the software version. For example, the
API version for FTD version 6.3.0 is v2, so the base URL would be:
In the API Explorer, if you scroll to the bottom of the page, you can
see information on the base URL (without the server name) and API version.
