Use `?validate_only=true` as an optional query parameter to only run validation without persisting changes. ##### Security
API Token The preferred authorization scheme for interacting with the Cloudflare API. Create a token. **Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY
API Email + API Key The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key. **Example:**X-Auth-Email: user@example.com The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys. **Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194

ModifiedInterconnects \[]CfInterconnectBulkUpdateResponseModifiedInterconnectOptional ID stringOptional Identifier maxLength32 Link to this property AutomaticReturnRouting boolOptional True if automatic stateful return routing should be enabled for a tunnel, false otherwise. Requires the coupler_integration account flag to be enabled; requests setting this to true without that flag will be rejected. Link to this property
BGP CfInterconnectBulkUpdateResponseModifiedInterconnectsBGPOptional DeprecatedAsNo int64Optional Deprecated. Use customer\_asn. formatint32 Link to this property DeprecatedCloudflareEndpoint stringOptional Read-only for v1.5; derived from interface\_address. formatipv4 Link to this property CustomerASN int64Optional ASN used on the customer end of the BGP session. formatint32 Link to this property DeprecatedCustomerEndpoint stringOptional Read-only for v1.5; derived from interface\_address. formatipv4 Link to this property ExportFilterID stringOptional ID of the BGP filter profile applied to routes advertised to the customer. Link to this property ExtraPrefixes \[]stringOptional Prefixes in this list will be advertised to the customer device, in addition to the routes in the Magic routing table. Link to this property ImportFilterID stringOptional ID of the BGP filter profile applied to routes received from the customer. Link to this property Md5Key stringOptional MD5 key to use for session authentication. Note that *this is not a security measure*. MD5 is not a valid security mechanism, and the key is not treated as a secret value. This is *only* supported for preventing misconfiguration, not for defending against malicious attacks. The MD5 key, if set, must be of non-zero length and consist only of the following types of character: - ASCII alphanumerics: [a-zA-Z0-9] - Special characters in the set '!@#$%^&*()+[]{}<>/.,;:_-~= |\` In other words, MD5 keys may contain any printable ASCII character aside from newline (0x0A), quotation mark ("), vertical tab (0x0B), carriage return (0x0D), tab (0x09), form feed (0x0C), and the question mark (?). Requests specifying an MD5 key with one or more of these disallowed characters will be rejected. Link to this property
Link to this property ColoName stringOptional The name of the interconnect. The name cannot share a name with other tunnels. Link to this property CreatedOn TimeOptional The date and time the tunnel was created. formatdate-time Link to this property Description stringOptional An optional description of the interconnect. Link to this property
GRE CfInterconnectBulkUpdateResponseModifiedInterconnectsGREOptional Omitted in responses for version 1.5 interconnects. CloudflareEndpoint stringOptional The IP address assigned to the Cloudflare side of the GRE tunnel created as part of the Interconnect. Link to this property
Link to this property
HealthCheck CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckOptional
Direction CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckDirectionOptional The direction of the flow of the healthcheck. Either unidirectional, where the probe comes to you via the interconnect and the result comes back to Cloudflare via the open Internet, or bidirectional where both the probe and result come and go via the interconnect. One of the following: const CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckDirectionUnidirectional CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckDirection = "unidirectional" Link to this property const CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckDirectionBidirectional CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckDirection = "bidirectional" Link to this property
Link to this property Enabled boolOptional Determines whether to run healthchecks for a tunnel. Link to this property
Rate HealthCheckRateOptional How frequent the health check is run. The default value is mid. One of the following: const HealthCheckRateLow HealthCheckRate = "low" Link to this property const HealthCheckRateMid HealthCheckRate = "mid" Link to this property const HealthCheckRateHigh HealthCheckRate = "high" Link to this property
Link to this property Source stringOptional The source IPv4 address used for bidirectional health checks. Supported only for version 1.5 interconnects. It is required when direction is bidirectional and must be omitted (and is cleared) when direction is unidirectional. The address must be within RFC1918 space, the approved link-local range 169.254.240.0/20, or the Cloudflare reserved range 198.41.199.224/27. Link to this property
Target CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckTargetUnionOptional The destination address in a request type health check. After the healthcheck is decapsulated at the customer end of the tunnel, the ICMP echo will be forwarded to this address. This field defaults to customer_gre_endpoint address. This field is ignored for bidirectional healthchecks as the interface\_address (not assigned to the Cloudflare side of the tunnel) is used as the target. Must be in object form if the x-magic-new-hc-target header is set to true and string form if x-magic-new-hc-target is absent or set to false. One of the following:
type CfInterconnectBulkUpdateResponseModifiedInterconnectsHealthCheckTargetMagicHealthCheckTarget struct{…} The destination address in a request type health check. After the healthcheck is decapsulated at the customer end of the tunnel, the ICMP echo will be forwarded to this address. This field defaults to customer_gre_endpoint address. This field is ignored for bidirectional healthchecks as the interface\_address (not assigned to the Cloudflare side of the tunnel) is used as the target. Effective stringOptional The effective health check target. If ‘saved’ is empty, then this field will be populated with the calculated default value on GET requests. Ignored in POST, PUT, and PATCH requests. Link to this property Saved stringOptional The saved health check target. Setting the value to the empty string indicates that the calculated default value will be used. Link to this property

Link to this property
Type HealthCheckTypeOptional The type of healthcheck to run, reply or request. The default value is reply. One of the following: const HealthCheckTypeReply HealthCheckType = "reply" Link to this property const HealthCheckTypeRequest HealthCheckType = "request" Link to this property
Link to this property
Link to this property InterfaceAddress stringOptional The IPv4 interface address for the interconnect. For MPLS Interconnects, use a /30 or /31 prefix. For GRE Interconnects, a /30 or /31 prefix may be used. Version 1.5 interconnects require a /31 prefix and may also use a prefix from the account’s authorized prefixes; otherwise, select the subnet from RFC 1918 or the approved link-local ranges. Link to this property InterfaceAddress6 stringOptional A 127 bit IPV6 prefix from within the virtual\_subnet6 prefix space with the address being the first IP of the subnet and not same as the address of virtual\_subnet6. Eg if virtual\_subnet6 is 2606:54c1:7:0:a9fe:12d2::/127 , interface\_address6 could be 2606:54c1:7:0:a9fe:12d2:1:200/127 Link to this property ModifiedOn TimeOptional The date and time the tunnel was last modified. formatdate-time Link to this property Mtu int64Optional The Maximum Transmission Unit (MTU) in bytes for the interconnect. The minimum value is 576. Link to this property Name stringOptional The name of the interconnect. The name cannot share a name with other tunnels. Link to this property Version stringOptional Immutable interconnect version configured at creation time. One of: - “1” - “1.5” - “2” Link to this property VirtualPortReservationID stringOptional An identifier that correlates this interconnect with the corresponding V2 CNI interconnect resource. maxLength32 Link to this property
