Create Certificate

POST/certificates

Create an Origin CA certificate. For keyless-certificate requests, zone_id is required and the response contains only id, certificate, and expires_on. You can use an Origin CA Key as your User Service Key or an API token when calling this endpoint (see above).

hostnames: array of string

Array of hostnames or wildcard names bound to the certificate. Hostnames must be fully qualified domain names (FQDNs) belonging to zones on your account (e.g., example.com or sub.example.com).
