When creating a third party VPN using an IKEv2 peer there are several IPsec policy presets available in the web dashboard: AWS, Azure, Zscaler, Umbrella.
Calling updateOrganizationApplianceVpnThirdPartyVPNPeers with an IKEv2 peer with ipsecPoliciesPreset set to 'zscaler' returns an error:
400 Bad Request, {'errors': ['Peer "XXX": Invalid IPsec policy preset. Must be one of the following: default, aws, or azure.']}
Seems like the 'zscaler' and 'umbrella' options need to be added to the API.
