CustomCertificate object { id, zone_id, bundle_method, 12 more }
id: string

Identifier.

maxLength32
zone_id: string

Identifier.

maxLength32
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A ubiquitous bundle has the highest probability of being verified everywhere, even by clients using outdated or unusual trust stores.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.

custom_csr_id: optional string

The identifier for the Custom CSR that was used.

expires_on: optional string

When the certificate from the authority expires.

formatdate-time
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.

hosts: optional array of string
issuer: optional string

The certificate authority that issued the certificate.

keyless_server: optional KeylessCertificate { id, created_on, enabled, 7 more }
modified_on: optional string

When the certificate was last modified.

formatdate-time
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)”

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.

signature: optional string

The type of hash used for the certificate.

status: optional "active" or "expired" or "deleted" or 2 more

Status of the zone’s custom SSL.

One of the following:
"active"
"expired"
"deleted"
"pending"
"initializing"
uploaded_on: optional string

When the certificate was uploaded to Cloudflare.

formatdate-time
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"
One of the following:
"us"
"eu"
"highest_security"
