`Relay`	dict	Network relay	—	—	—
`HTTP3RelayURL` The URL or URI template, as defined in RFC 9298, of a relay server that's reachable using HTTP/3 and supports proxying TCP and UDP using the CONNECT method. Each relay needs to include either 'HTTP2RelayURL' or 'HTTP3RelayURL', or it can include both.	string	HTTP/3 relay URL	The URL or URI template, as defined in RFC 9298, of a relay server that's reachable using HTTP/3 and supports proxying TCP and UDP using the CONNECT method. Each relay needs to include either 'HTTP2RelayURL' or 'HTTP3RelayURL', or it can include both.	—	—
`HTTP2RelayURL` The URL or URI template, as defined in RFC 9298, of a relay server that's reachable using HTTP/2 and supports proxying TCP and UDP using the CONNECT method. Each relay needs to include either 'HTTP2RelayURL' or 'HTTP3RelayURL', or it can include both.	string	HTTP/2 relay URL	The URL or URI template, as defined in RFC 9298, of a relay server that's reachable using HTTP/2 and supports proxying TCP and UDP using the CONNECT method. Each relay needs to include either 'HTTP2RelayURL' or 'HTTP3RelayURL', or it can include both.	—	—
`AdditionalHTTPHeaderFields` A dictionary that contains custom HTTP header keys and values to add to each request. The dictionary key name represents the HTTP header field name to use, and the dictionary value is the string to use as the HTTP header field value.	dict	Additional HTTP header fields	A dictionary that contains custom HTTP header keys and values to add to each request. The dictionary key name represents the HTTP header field name to use, and the dictionary value is the string to use as the HTTP header field value.	—	—
`{{key}}`required	string	—	—	—	—
`{{value}}`required The HTTP header field value for the corresponding header field name.	string	—	The HTTP header field value for the corresponding header field name.	—	—
`ANY`required The HTTP header field value for the corresponding header field name.	string	—	The HTTP header field value for the corresponding header field name.	—	—
`PayloadCertificateUUID` The UUID that points to an identity certificate payload, which the system uses to authenticate the user to the relay server.	string	Certificate UUID	The UUID that points to an identity certificate payload, which the system uses to authenticate the user to the relay server.	—	—
`RawPublicKeys` An array of DER-encoded raw public keys that the system uses to authenticate the server during a TLS handshake. The server needs to use one of the keys in the handshake to authenticate. If this array is empty, the system uses the default TLS trust evaluation.	array	Raw public keys	An array of DER-encoded raw public keys that the system uses to authenticate the server during a TLS handshake. The server needs to use one of the keys in the handshake to authenticate. If this array is empty, the system uses the default TLS trust evaluation.	—	—
`RawPublicKeysElement`	data	Raw public key element	—	—	—
`MatchDomains` A list of domain strings that the system uses to determine which connection to route through the servers in 'Relays'. Any connection that matches a domain in the list exactly or is a subdomain of the listed domain uses the relay servers, unless it matches a domain in 'ExcludedDomains'. If this list and 'MatchFQDNs' are empty, the system routes traffic to all domains to the relay servers, except those that match an excluded domain or excluded FQDN.	array	Match domains	A list of domain strings that the system uses to determine which connection to route through the servers in 'Relays'. Any connection that matches a domain in the list exactly or is a subdomain of the listed domain uses the relay servers, unless it matches a domain in 'ExcludedDomains'. If this list and 'MatchFQDNs' are empty, the system routes traffic to all domains to the relay servers, except those that match an excluded domain or excluded FQDN.	—	—
`MatchDomainsElement`	string	Match domains element	—	—	—
`ExcludedDomains` A list of domain strings to exclude from routing through the servers in 'Relays'. Any connection that matches a domain in the list exactly or is a subdomain of the listed domain won't use the relay server.	array	Excluded domains	A list of domain strings to exclude from routing through the servers in 'Relays'. Any connection that matches a domain in the list exactly or is a subdomain of the listed domain won't use the relay server.	—	—
`ExcludedDomainsElement`	string	Excluded domains element	—	—	—
`RelayUUID` not on macOS A globally unique identifier for this relay configuration. The system uses this UUID to route managed apps through the servers in 'Relays'. This key is required for user enrollment.	string	Relay UUID	A globally unique identifier for this relay configuration. The system uses this UUID to route managed apps through the servers in 'Relays'. This key is required for user enrollment.	—	—
`MatchFQDNs` iOS 18.4+ · macOS 15.4+ · tvOS 18.4+ · visionOS 2.4+ A list of Fully Qualified Domain Names (FQDNs) to route through the servers contained in 'Relays'. Any connection that matches an FQDN in the list exactly uses the relay servers. If this list and 'MatchDomains' are empty, the system routes traffic to all domains to the relay servers, except those that match an excluded domain or excluded FQDN.	array	Match FQDNs	A list of Fully Qualified Domain Names (FQDNs) to route through the servers contained in 'Relays'.

Any connection that matches an FQDN in the list exactly won't use the relay server. When 'MatchDomains' is also present, any FQDN listed in the list should be a subdomain of at least one 'MatchDomain' value, otherwise it won't have any effect.	array	Excluded FQDNs	A list of Fully Qualified Domain Names (FQDNs) to exclude from routing through the servers contained in 'Relays'.
