## Re-prioritize SSL Certificates

`client.CustomCertificates.Prioritize.Update(ctx, params) (*SinglePage[CustomCertificate], error)`

**put** `/zones/{zone_id}/custom_certificates/prioritize`

If a zone has multiple SSL certificates, you can set the order in which they should be used during a request. The higher priority will break ties across overlapping 'legacy_custom' certificates.

### Parameters

- `params PrioritizeUpdateParams`

  - `ZoneID param.Field[string]`

    Path param: Identifier.

  - `Certificates param.Field[[]PrioritizeUpdateParamsCertificate]`

    Body param: Array of ordered certificates.

    - `ID string`

      Identifier.

    - `Priority float64`

      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.

### Returns

- `type CustomCertificate struct{…}`

  - `ID string`

    Identifier.

  - `ZoneID string`

    Identifier.

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    A ubiquitous bundle has the highest probability of being verified everywhere, even by clients using outdated or unusual trust stores.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

    - `const BundleMethodUbiquitous BundleMethod = "ubiquitous"`

    - `const BundleMethodOptimal BundleMethod = "optimal"`

    - `const BundleMethodForce BundleMethod = "force"`

  - `CustomCsrID string`

    The identifier for the Custom CSR that was used.

  - `ExpiresOn Time`

    When the certificate from the authority expires.

  - `GeoRestrictions GeoRestrictions`

    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 GeoRestrictionsLabel`

      - `const GeoRestrictionsLabelUs GeoRestrictionsLabel = "us"`

      - `const GeoRestrictionsLabelEu GeoRestrictionsLabel = "eu"`

      - `const GeoRestrictionsLabelHighestSecurity GeoRestrictionsLabel = "highest_security"`

  - `Hosts []string`

  - `Issuer string`

    The certificate authority that issued the certificate.

  - `KeylessServer KeylessCertificate`

    - `ID string`

      Keyless certificate identifier tag.

    - `CreatedOn Time`

      When the Keyless SSL was created.

    - `Enabled bool`

      Whether or not the Keyless SSL is on or off.

    - `Host string`

      The keyless SSL name.

    - `ModifiedOn Time`

      When the Keyless SSL was last modified.

    - `Name string`

      The keyless SSL name.

    - `Permissions []string`

      Available permissions for the Keyless SSL for the current user requesting the item.

    - `Port float64`

      The keyless SSL port used to communicate between Cloudflare and the client's Keyless SSL server.

    - `Status KeylessCertificateStatus`

      Status of the Keyless SSL.

      - `const KeylessCertificateStatusActive KeylessCertificateStatus = "active"`

      - `const KeylessCertificateStatusDeleted KeylessCertificateStatus = "deleted"`

    - `Tunnel Tunnel`

      Configuration for using Keyless SSL through a Cloudflare Tunnel

      - `PrivateIP string`

        Private IP of the Key Server Host

      - `VnetID string`

        Cloudflare Tunnel Virtual Network ID

  - `ModifiedOn Time`

    When the certificate was last modified.

  - `PolicyRestrictions 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 float64`

    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 string`

    The type of hash used for the certificate.

  - `Status CustomCertificateStatus`

    Status of the zone's custom SSL.

    - `const CustomCertificateStatusActive CustomCertificateStatus = "active"`

    - `const CustomCertificateStatusExpired CustomCertificateStatus = "expired"`

    - `const CustomCertificateStatusDeleted CustomCertificateStatus = "deleted"`

    - `const CustomCertificateStatusPending CustomCertificateStatus = "pending"`

    - `const CustomCertificateStatusInitializing CustomCertificateStatus = "initializing"`

  - `UploadedOn Time`

    When the certificate was uploaded to Cloudflare.

    Certificates: cloudflare.F([]custom_certificates.PrioritizeUpdateParamsCertificate{custom_certificates.PrioritizeUpdateParamsCertificate{

    }, custom_certificates.PrioritizeUpdateParamsCertificate{

    }}),
  })

    panic(err.Error())
  }
