Update and deploy rulesets

You can use the API to update basic properties of a ruleset (currently only the description) and the list of rules in the ruleset.

Use one of the following API endpoints:

Operation	Method + Endpoint
Update an account ruleset	PUT /accounts/{account_id}/rulesets/{ruleset_id}
Update a zone ruleset	PUT /zones/{zone_id}/rulesets/{ruleset_id}
Update an account entry point ruleset	PUT /accounts/{account_id}/rulesets/phases/{phase_name}/entrypoint
Update a zone entry point ruleset	PUT /zones/{zone_id}/rulesets/phases/{phase_name}/entrypoint

Note

You cannot update the name of the ruleset or its type. Do not include these fields in the data field of your PUT request.

Example - Set the rules of a ruleset

Use this API method to set the rules of a ruleset. You must include all the rules you want to associate with the ruleset in every request.

curl --request PUT \
https://api.cloudflare.com/client/v4/zones/{zone_id}/rulesets/{ruleset_id} \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '{
  "rules": [
    {
      "action": "execute",
      "action_parameters": {
        "id": "<MANAGED_RULESET_ID>"
      },
      "expression": "true"
    }
  ]
}'

{
  "result": {
    "id": "<RULESET_ID>",
    "name": "Zone-level phase entry point",
    "description": "This ruleset executes a managed ruleset.",
    "kind": "zone",
    "version": "4",
    "rules": [
      {
        "id": "<RULE_ID>",
        "version": "2",
        "action": "execute",
        "expression": "true",
        "action_parameters": {
          "id": "<MANAGED_RULESET_ID>"
        },
        "last_updated": "2023-03-17T15:42:37.917815Z"
      }
    ],
    "last_updated": "2023-03-17T15:42:37.917815Z",
    "phase": "http_request_firewall_managed"
  },
  "success": true,
  "errors": [],
  "messages": []
}

Example - Deploy a ruleset

To deploy a ruleset, create a rule with "action": "execute" that executes the ruleset, and add the ruleset ID to the action_parameters field in the id parameter.

The following example deploys a managed ruleset to the zone-level http_request_firewall_managed phase of a zone ({zone_id}).

curl --request PUT \
https://api.cloudflare.com/client/v4/zones/{zone_id}/rulesets/phases/http_request_firewall_managed/entrypoint \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '{
  "rules": [
    {
      "action": "execute",
      "action_parameters": {
        "id": "<MANAGED_RULESET_ID>"
      },
      "expression": "true",
      "description": "Execute Cloudflare Managed Ruleset on my phase entry point"
    }
  ]
}'

{
  "result": {
    "id": "<ZONE_PHASE_RULESET_ID>",
    "name": "Zone-level phase entry point",
    "description": "",
    "kind": "zone",
    "version": "4",
    "rules": [
      {
        "id": "<RULE_ID_1>",
        "version": "1",
        "action": "execute",
        "action_parameters": {
          "id": "<MANAGED_RULESET_ID>",
          "version": "latest"
        },
        "expression": "true",
        "description": "Execute Cloudflare Managed Ruleset on my phase entry point",
        "last_updated": "2023-03-21T11:02:08.769537Z",
        "ref": "<RULE_REF_1>",
        "enabled": true
      }
    ],
    "last_updated": "2023-03-21T11:02:08.769537Z",
    "phase": "http_request_firewall_managed"
  },
  "success": true,
  "errors": [],
  "messages": []
}

Example - Update ruleset description

You can use this API method to update the description of an existing ruleset or phase entry point.

The response will include the complete ruleset definition, including all the rules.

Note

You cannot update the description or the rules in a managed ruleset. You can only define overrides to customize the ruleset behavior.

curl --request PUT \
https://api.cloudflare.com/client/v4/zones/{zone_id}/rulesets/{ruleset_id} \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '{
  "description": "My updated phase entry point"
}'

{
  "result": {
    "id": "<RULESET_ID>",
    "name": "Zone entry point",
    "description": "My updated phase entry point",
    "kind": "zone",
    "version": "4",
    "rules": [
      // (...)
    ],
    "last_updated": "2023-03-30T10:49:11.006109Z",
    "phase": "http_request_firewall_managed"
  },
  "success": true,
  "errors": [],
  "messages": []
