## Delete Hostname Client Certificate

`client.OriginTLSClientAuth.HostnameCertificates.Delete(ctx, certificateID, body) (*HostnameCertificateDeleteResponse, error)`

**delete** `/zones/{zone_id}/origin_tls_client_auth/hostnames/certificates/{certificate_id}`

Removes a client certificate used for authenticated origin pulls on a specific hostname.
Note: Before deleting the certificate, you must first invalidate the hostname for client authentication by sending a PUT request with `enabled` set to null. After invalidating the association, the certificate can be safely deleted.
