KSC API use cases examples - host isolation with KES/KEA [KSC for Windows]

Description and cautions
The article is giving some use cases examples of KSC API calls to ease one's start using the API. In that KB we are looking at host isolation with KES/KEA scenario.
For the Windows version of cURL, you need to specify that the arguments need to be escaped with "\", otherwise there will be an error. For example: 'Authorization: KSCBasic user=\"YXBpLXVzZXI=\", pass=\"cGFzc3dvcmQ=\", internal=\"1\"'
Details
Prerequisites
- internal user: api-user
Example
- KSC address - 127.0.0.1 (the address can also be external)
- API Port - 13299 (default)
- User: api-user (intrental KSC user), base64: YXBpLXVzZXI=
- Password: password, base64: cGFzc3dvcmQ=
-
Credentials:
UserPasswordapi-user password Base64: YXBpLXVzZXI= cGFzc3dvcmQ= - Authentication, type: Authenticated session, other types: KSC Open API description
- Requests are in cUrl and http formats, as an alternative it is also possible to use Python library (KlAkOAPI Python package)
Login
Start connection to KSC (Session::StartSession)
--header 'Authorization: KSCBasic user="YXBpLXVzZXI=", pass="cGFzc3dvcmQ=", internal="1"'
|
Username and password should be encoded to base64 format as part of a secure HTTPS session. For example, https://www.base64encode.org/ can be used for encoding.

Find Host
Find host by filter string (HostGroup::FindHosts)
Filter string, contains a condition over host attributes, see also Search filter syntax.
We use "KLHST_WKS_DN" - Host display name
POST /api/v1.0/HostGroup.FindHosts HTTP/1.1
Host: localhost:13299

With NWC web console KSC create local network exteption for VPN:
1) Open host properties → Applications → KEA
2) Open tab APP Settings → Network Isolation → Isolation on detection
3) Add rule for RDP → click "OK" → click "Save"
