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:

Request
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"
}'

The response includes the ruleset ID of the new custom ruleset in the id field:

Response
{
"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.
