CustomCertificate object {id, zone\_id, bundle\_method, 12 more }

id: string Custom certificate identifier tag. maxLength36 Link to this property zone\_id: string Identifier. maxLength32 Link to this property bundle\_method: optional BundleMethod A ubiquitous bundle has the highest probability of being verified everywhere, even by clients using outdated or unusual trust stores. An optimal bundle uses the shortest chain and newest intermediates. And the force bundle verifies the chain, but does not otherwise modify it. Link to this property custom\_csr\_id: optional string The identifier for the Custom CSR that was used. Link to this property expires\_on: optional string When the certificate from the authority expires. formatdate-time Link to this property geo\_restrictions: optional GeoRestrictions { label } Specify the region where your private key can be held locally for optimal TLS performance. HTTPS connections to any excluded data center will still be fully encrypted, but will incur some latency while Keyless SSL is used to complete the handshake with the nearest allowed data center. Options allow distribution to only to U.S. data centers, only to E.U. data centers, or only to highest security data centers. Default distribution is to all Cloudflare datacenters, for optimal performance. Link to this property hosts: optional array of string Link to this property issuer: optional string The certificate authority that issued the certificate. Link to this property keyless\_server: optional KeylessCertificate { id, created\_on, enabled, 7 more } Link to this property modified\_on: optional string When the certificate was last modified. formatdate-time Link to this property policy\_restrictions: optional string The policy restrictions returned by the API. This field is returned in responses when a policy has been set. The API accepts the “policy” field in requests but returns this field as “policy\_restrictions” in responses. Specifies the region(s) where your private key can be held locally for optimal TLS performance. Format is a boolean expression, for example: “(country: US) or (region: EU)” Link to this property priority: optional number The order/priority in which the certificate will be used in a request. The higher priority will break ties across overlapping ‘legacy\_custom’ certificates, but ‘legacy\_custom’ certificates will always supercede ‘sni\_custom’ certificates. Link to this property signature: optional string The type of hash used for the certificate. Link to this property

status: optional "active"or "expired"or "deleted"or 2 more Status of the zone’s custom SSL.

One of the following: "active" Link to this property "expired" Link to this property "deleted" Link to this property "pending" Link to this property "initializing" Link to this property

Link to this property uploaded\_on: optional string When the certificate was uploaded to Cloudflare. formatdate-time Link to this property

GeoRestrictions object {label } Specify the region where your private key can be held locally for optimal TLS performance. HTTPS connections to any excluded data center will still be fully encrypted, but will incur some latency while Keyless SSL is used to complete the handshake with the nearest allowed data center. Options allow distribution to only to U.S. data centers, only to E.U. data centers, or only to highest security data centers. Default distribution is to all Cloudflare datacenters, for optimal performance.

label: optional "us"or "eu"or "highest\_security"
