Create a cache rule

Decides what the edge caches, for how long, and which safety bypasses apply. A domain may hold several cache rules with different tradeoffs; each is self-contained.

Requires rules.edit.

domain
required
string

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

Example
example.com
Media type application/json
object
record_id

Deprecated single-record scope. Prefer record_ids.

integer | null
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>
ttl_sec

How long an entry stays fresh, in seconds. 0 uses the default.

integer
refresh_sec

Background refresh interval in seconds — the entry is re-fetched this often while still being served. 0 disables it.

integer
with_qs

Include the query string in the cache key. Off means ?a=1 and ?a=2 share one entry.

boolean
scope

What the rule caches among the paths it already matches.

  • default — static assets only, chosen by file extension.
  • everything — every cacheable response, HTML included.

There is no “custom” scope: narrow what you cache by scoping path_includes instead.

string
Allowed values: default everything
bypass_authorization

Skip caching requests that carry an Authorization header. Leave on unless you are certain the response is not user-specific.

boolean
default: true
bypass_set_cookie

Skip caching responses that set a cookie. Turning this off can serve one visitor’s session to another — only do it for responses you know are anonymous.

boolean
default: true
respect_client_no_store

Honour Cache-Control: no-store from the client.

boolean
default: true
respect_origin_cache_control

Honour the origin’s Cache-Control directives.

boolean
default: true
respect_origin_max_age

Use the origin’s max-age instead of ttl_sec.

boolean
default: true
bypass_wp_admin

Never cache WordPress admin and login paths.

boolean
default: true

Rule created.

Media type application/json
object
id
integer
domain_id
integer
record_id

Deprecated single-record scope. Prefer record_ids. Absent for zone-wide rules.

integer
record_ids

The proxied DNS records this rule applies to. Empty or absent means zone-wide — every proxied record of the domain.

Array<integer>
type
string
Allowed values: cache drop redirect rewrite waf captcha rate_limit bot_route origin_pool origin_route fingerprint error_page
enabled
boolean
priority

Evaluation order; lower runs first. Defaults to 100.

integer
host_pattern

Optional hostname filter. Empty means the rule is not host-scoped.

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
created_at
string format: date-time
updated_at
string format: date-time
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

respect_origin_max_age

Use the origin’s max-age instead of ttl_sec.

boolean

bypass_wp_admin

Never cache WordPress admin and login paths.

boolean

Example

}

Malformed body, an invalid field value, or record_ids containing a record that does not belong to this domain.

Media type application/json

The error shape used by every endpoint. error is always present. code is present only on the failures that have one — do not require it, and do not parse error to recover it.

object
error
required

Human-readable description of what went wrong.

string
code

Stable machine-readable reason. Present on some failures only; the wording of error may change, this will not.

  • account_suspended403. The account behind the credential has been switched off, by an admin or by its provider. Every authenticated route answers this, so treat it as terminal rather than retrying.
  • domain_disabled409, not 403. You have every right to the operation; the domain is simply switched off and is not being served, so its configuration cannot change. It stays readable, and writes work again once it is enabled.
  • managed_by_reseller403. The account is a reseller’s client and this surface belongs to its provider. See If your account is managed by a reseller.
  • invite_email_mismatch403 from POST /invites/{token}/accept. The invitation was addressed to a different email; the body also carries invited_email, masked.

A panel session — not an API key — can additionally see session_check_failed on a 503, which means the session could not be verified, not that it is invalid. Retry it; do not discard the token.

string
Examples
Example foreignRecords
{
"error": "record_ids do not belong to this domain"
}

Missing, malformed, revoked or expired API key, or a key whose owning user row is gone. A key whose owning account has merely been deactivated is not this: that is 403 with code: account_suspended, because the credential itself is intact and re-issuing it changes nothing.

Examples
Example invalidKey
{
"error": "invalid API key"
}

The key is read-only, your role on the domain lacks rules.edit (a viewer has domain.view and nothing more), or the domain’s plan does not include this rule type or allows fewer rules of it than you already have.

Example
{

}

No such domain, or you hold no role on it at all.

It no longer means “your role is too low”. The rules endpoints resolve access through the shared domain guard, which answers 403 when the caller can see the domain but lacks rules.edit, and 409 with code: domain_disabled when the domain is switched off and the request is a write. Reading is open to every role, so a GET can only fail here.
