'Merges a certificate or a certificate chain with a key pair existing on
the server.
The MergeCertificate operation performs the merging of a certificate or
certificate chain with a key pair currently available in the service.
Authorization: requires the certificates/update permission.
:param vault_base_url: The vault name, for example
https://myvault.vault.azure.net.
:type vault_base_url: str
:param certificate_name: The name of the certificate.
:type certificate_name: str
:param x509_certificates: The certificate or the certificate chain to
merge.
:type x509_certificates: list of bytearray
:param certificate_attributes: The attributes of the certificate
(optional).
:type certificate_attributes: :class:`CertificateAttributes
<azure.keyvault.models.CertificateAttributes>`
:param tags: Application specific metadata in the form of key-value
pairs.
:type tags: dict
:param dict custom_headers: headers that will be added to the request
:param bool raw: returns the direct response alongside the
deserialized response
