Authorizations

Section titled “Authorizations ”

Parameters

Section titled “ Parameters ”

Path Parameters

Section titled “Path Parameters ”
domain
required
string

The domain name (for example example.com) — not a numeric id.

Example 
example.com
ruleId
required
integer

Numeric id of the rule.

Request Body required

Section titled “Request Body required ”
Media type application/json
object
record_id

Deprecated single-record scope. Prefer record_ids.

integer
nullable
record_ids

Scope the rule to these proxied records. Omit or send an empty array for a zone-wide rule. Every id must belong to this domain.

Array<integer>
enabled
boolean
default: true
priority
integer
default: 100
host_pattern
string
host_match_type

How host_pattern is matched. The empty string means “no host filter”, and is the only valid value when host_pattern is empty — the two fields are set and cleared together.

string
Allowed values: "" exact wildcard regex
action_mode
  • enforce — the rule acts (block, redirect, challenge, …).
  • dry_run — the rule matches and is logged as “would have acted”, but the request reaches the origin unchanged. Use it to test a rule safely.

Not every rule type honours this; cache ignores it.

string
Allowed values: enforce dry_run
path_match_type

How path_includes and path_excludes are interpreted.

string
Allowed values: wildcard regex
path_includes

Paths the rule applies to. Defaults to ["/*"] — everything.

Array<string>
path_excludes

Paths carved back out of path_includes.

Array<string>
limit

Requests allowed per window_sec for one key.

integer
window_sec

Length of the counting window, in seconds.

integer
default: 60
key_by

How requests are bucketed. ip counts everything from one address together; ip_path counts each path separately per address.

string
default: ip
Allowed values: ip ip_path
on_breach

What happens to requests above the limit.

string
default: drop
Allowed values: drop captcha
burst

Extra requests tolerated momentarily above limit.

integer
