Create a custom ruleset

Use the Create an account ruleset operation to create a custom ruleset, making sure that you:

• Set the kind field to custom.
• Specify the name of the phase where you want to create the custom ruleset in the phase field.

Example

The following request creates a new custom ruleset. The response will include the ID of the new custom ruleset in the id field.

curl https://api.cloudflare.com/client/v4/accounts/{account_id}/rulesets \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Content-Type: application/json" \
--data '{
  "name": "Custom Ruleset 1",
  "description": "My First Custom Ruleset",
  "kind": "custom",
  "phase": "http_request_firewall_custom"
}'

{
  "result": {
    "id": "f82ccda3d21f4a02825d3fe45b5e1c10",
    "name": "Custom Ruleset 1",
    "description": "My First Custom Ruleset",
    "kind": "custom",
    "version": "1",
    "last_updated": "2021-03-09T10:27:30.636197Z",
    "phase": "http_request_firewall_custom"
  },
  "success": true,
  "errors": [],
  "messages": []
}

You can include a list of rules in the custom ruleset creation request. If you have not added any rules, refer to Add rules to a custom ruleset for more information.
