Path ParametersExpand Collapse

zone_id: string

Defines an identifier.

maxLength32

Body ParametersJSONExpand Collapse

action: object { mode, response, timeout }

The action to perform when the threshold of matched traffic within the configured period is exceeded.

mode: optional "simulate" or "ban" or "challenge" or 2 more

The action to perform.

One of the following:

"simulate"

"ban"

"challenge"

"js_challenge"

"managed_challenge"

response: optional object { body, content_type }

A custom content type and reponse to return when the threshold is exceeded. The custom response configured in this object will override the custom error for the zone. This object is optional. Notes: If you omit this object, Cloudflare will use the default HTML error page. If “mode” is “challenge”, “managed_challenge”, or “js_challenge”, Cloudflare will use the zone challenge pages and you should not provide the “response” object.

body: optional string

The response body to return. The value must conform to the configured content type.

maxLength10240

content_type: optional string

The content type of the body. Must be one of the following: text/plain, text/xml, or application/json.

maxLength50

timeout: optional number

The time in seconds during which Cloudflare will perform the mitigation action. Must be an integer value greater than or equal to the period. Notes: If “mode” is “challenge”, “managed_challenge”, or “js_challenge”, Cloudflare will use the zone’s Challenge Passage time and you should not provide this value.

maximum86400

match: object { headers, request, response }

Determines which traffic the rate limit counts towards the threshold.

headers: optional array of object { name, op, value }

name: optional string

The name of the response header to match.

op: optional "eq" or "ne"

The operator used when matching: eq means “equal” and ne means “not equal”.

One of the following:

"eq"

"ne"

value: optional string

The value of the response header, which must match exactly.

request: optional object { methods, schemes, url }

methods: optional array of "GET" or "POST" or "PUT" or 4 more

The HTTP methods to match. You can specify a subset (for example, ['POST','PUT']) or all methods (['_ALL_']). This field is optional when creating a rate limit.

One of the following:

"GET"

"POST"

"PUT"

"DELETE"

"PATCH"

"HEAD"

"_ALL_"

schemes: optional array of string

The HTTP schemes to match. You can specify one scheme (['HTTPS']), both schemes (['HTTP','HTTPS']), or all schemes (['_ALL_']). This field is optional.

url: optional string

The URL pattern to match, composed of a host and a path such as example.org/path*. Normalization is applied before the pattern is matched. * wildcards are expanded to match applicable traffic. Query strings are not matched. Set the value to * to match all traffic to your zone.

maxLength1024

response: optional object { origin_traffic }

origin_traffic: optional boolean

When true, only the uncached traffic served from your origin servers will count towards rate limiting. In this case, any cached traffic served by Cloudflare will not count towards rate limiting. This field is optional. Notes: This field is deprecated. Instead, use response headers and set “origin_traffic” to “false” to avoid legacy behaviour interacting with the “response_headers” property.

period: number

The time in seconds (an integer value) to count matching traffic. If the count exceeds the configured threshold within this period, Cloudflare will perform the configured action.

maximum86400

minimum10

threshold: number

The threshold that will trigger the configured mitigation action. Configure this value along with the period property to establish a threshold per period.
