--- title: Re-prioritize SSL Certificates --- [Skip to content](#_top) [API Reference](https://developers.cloudflare.com/api) [Custom Certificates](https://developers.cloudflare.com/api/resources/custom_certificates) [Prioritize](https://developers.cloudflare.com/api/resources/custom_certificates/subresources/prioritize) Copy Markdown Open in **Claude**Open in **ChatGPT**Open in **Cursor** --- **Copy Markdown****View as Markdown** # Re-prioritize SSL Certificates 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. ##### Security
API Token The preferred authorization scheme for interacting with the Cloudflare API. Create a token. **Example:**Authorization: Bearer Sn3lZJTBX6kkg7OdcBUAxOO963GEIyGQqnFTOFYY
API Email + API Key The previous authorization scheme for interacting with the Cloudflare API, used in conjunction with a Global API key. **Example:**X-Auth-Email: user@example.com The previous authorization scheme for interacting with the Cloudflare API. When possible, use API tokens instead of Global API keys. **Example:**X-Auth-Key: 144c9defac04969c7bfad8efaa8ea194

certificates: array of object {id, priority } Array of ordered certificates. id: optional string Custom certificate identifier tag. maxLength36 Link to this property 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. Link to this property

result: optional array of CustomCertificate { id, zone\_id, bundle\_method, 12 more } id: string Custom certificate identifier tag. maxLength36 Link to this property zone\_id: string Identifier. maxLength32 Link to this property
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BundleMethod A ubiquitous bundle has the highest probability of being verified everywhere, even by clients using outdated or unusual trust stores.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. One of the following: "ubiquitous" Link to this property "optimal" Link to this property "force" Link to this property
Link to this property custom\_csr\_id: optional string The identifier for the Custom CSR that was used. Link to this property expires\_on: optional string When the certificate from the authority expires. formatdate-time Link to this property
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.
label: optional "us"or "eu"or "highest\_security" One of the following: "us" Link to this property "eu" Link to this property "highest\_security" Link to this property

Link to this property hosts: optional array of string Link to this property issuer: optional string The certificate authority that issued the certificate. Link to this property
keyless\_server: optional KeylessCertificate { id, created\_on, enabled, 7 more } id: string Keyless certificate identifier tag. maxLength32 Link to this property created\_on: string When the Keyless SSL was created. formatdate-time Link to this property enabled: boolean Whether or not the Keyless SSL is on or off. Link to this property host: string The keyless SSL name. formathostname maxLength253 Link to this property modified\_on: string When the Keyless SSL was last modified. formatdate-time Link to this property name: string The keyless SSL name. maxLength180 Link to this property permissions: array of string Available permissions for the Keyless SSL for the current user requesting the item. Link to this property port: number The keyless SSL port used to communicate between Cloudflare and the client’s Keyless SSL server. maxLength65535 Link to this property
status: "active"or "deleted" Status of the Keyless SSL. One of the following: "active" Link to this property "deleted" Link to this property
Link to this property
tunnel: optional Tunnel { private\_ip, vnet\_id } Configuration for using Keyless SSL through a Cloudflare Tunnel. private\_ip: string Private IP of the Key Server Host. Link to this property vnet\_id: string Cloudflare Tunnel Virtual Network ID. Link to this property
Link to this property
Link to this property modified\_on: optional string When the certificate was last modified. formatdate-time Link to this property 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)” Link to this property 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. Link to this property signature: optional string The type of hash used for the certificate. Link to this property
status: optional "active"or "expired"or "deleted"or 2 more Status of the zone’s custom SSL. One of the following: "active" Link to this property "expired" Link to this property "deleted" Link to this property "pending" Link to this property "initializing" Link to this property
Link to this property uploaded\_on: optional string When the certificate was uploaded to Cloudflare. formatdate-time Link to this property
