Actions reference

The action of a rule tells Cloudflare how to handle matches for the rule expression .

Supported actions

The table below lists the actions available in the Rules language.

Some actions, like Block, will stop the evaluation of the remaining rules. The Skip action will skip the evaluation of some rules when there is a match, but the exact behavior will depend on the rule configuration.

The available actions depend on the phase where you are configuring the rule. Refer to each product’s documentation for details on the phase(s) supported by that product.

Action	Description	Stops rule evaluation?
Legacy CAPTCHA API value: `challenge`	Useful for ensuring that the visitor accessing the site is human, not automated. The client that made the request must pass a CAPTCHA challenge. If successful, Cloudflare accepts the matched request; otherwise, it is blocked.	Yes
JS Challenge API value: `js_challenge`	Useful for ensuring that bots and spam cannot access the requested resource; browsers, however, are free to satisfy the challenge automatically. The client that made the request must pass a Cloudflare JavaScript Challenge before proceeding. If successful, Cloudflare accepts the matched request; otherwise, it is blocked.	Yes
Managed Challenge (Recommended) API value: `managed_challenge`	Helps reduce the lifetimes of human time spent solving CAPTCHAs across the Internet. Depending on the characteristics of a request, Cloudflare will dynamically choose the appropriate type of challenge from the following actions based on specific criteria: Show a non-interactive challenge page (similar to the current JS Challenge). Present an invisible proof of work challenge to the browser. Show a custom interactive challenge (such as click a button). Show a CAPTCHA challenge.	Yes
Block API value: `block`	Matching requests are denied access to the site.	Yes
Skip API value: `skip`	Allows user to dynamically skip one or more security features or products for a request. Depending on the rule configuration, matching requests will skip the evaluation of one or more security features or products: Skip all remaining rules in the current ruleset Skip rulesets Skip rules of a ruleset Skip phases Skip specific security products that are not based on the Ruleset Engine The available skip options depend on the phase where you configure the rule. Refer to each product’s documentation for details.	No (but some rules may be skipped)
