Create advanced rules
Due to the highly technical aspect of the advanced rules functionality, the ability to create and edit these rules is currently only available through our API. Check out the following guides for details on how to create advanced rules and their key components:- API docs: Learn how to construct and manage advanced rules.
- Advanced rule objects and attributes: Get the list of all available objects you can use in rule expressions along with their respective attributes and types.
- Source field objects: Check the available source field objects you can use in your expressions along with their respective attributes and types.
Advanced rule properties
The advanced rule object contains the following properties:InfoEach rule can contain only one action ΓÇö
block, allow, captcha, handshake, or tag. If you use multiple actions in a single rule, the API will return an error.Description of the properties

Best practices
You can use our API documentation as a guide when constructing your own advanced rules. The following sections provide examples of advanced rules and the key CEL expressions used in each.NoteExamples are illustrative. Field values (paths, cookies, IPs, countries) should be adapted to the customer’s environment.
Rate limiting
Rate-limit IPs based on the number of requests they make to your website. This can be useful for mitigating scrapers or automated clients that generate a high volume of requests over a short period of time. The following rule limits the rate of requests an IP can send for 10 minutes when it exceeds 200 requests in 5 seconds, but excludes requests from mobile or web clients that have specific cookies. You can find more examples in our Rate limiting guide.- Python SDK

The penalty tag
The WAAP system appends thepenalty tag to the local (domain-related) IP record when an IP address triggers a block rule configured with an action_duration parameter.
To continue blocking an IP address after the original rule’s conditions are no longer met, include a penalty tag check in the rule’s source conditions (for example, using tags.exists('penalty')), or define a separate rule that targets requests carrying the penalty tag.
Block all penalty requests
The following rule blocks requests from IP addresses tagged with thepenalty tag, allowing block actions applied by other rules to persist.

Other examples
Validate a set of countries
Applies browser validation (JavaScript-based challenge) using thehandshake action to requests originating from specific countries, based on the whois.country field, while excluding requests that contain certain cookies.

Add clients to allow list
Allow requests from specific IP addresses or IP ranges by matching IP values in the rule condition.- Python SDK
- Go SDK
- curl
Tag and allow registered clients
Tag requests based on the presence of a specific cookie and allow requests associated with the assigned tag. When defining tag values in JSON, double quotation marks must be used, while string values inside rule expressions must be enclosed in single quotation marks.- Python SDK
- Go SDK
- curl
Define login pages
Tag requests that match specific URL patterns using string matching on the request URI.- Python SDK

List rules
Retrieve all advanced rules configured for a domain, including their current enabled state, actions, and CEL source expressions.- Python SDK
- Go SDK
- curl

Update a rule
Update any combination of a rule’s name, description, enabled state, action, phase, or source expression. Only fields included in the request body are changed. The API returns 204 with no body on success.- Python SDK
- Go SDK
- curl
Enable and disable a rule
Switch a rule between active and inactive without deleting it. Disabling a rule stops it from matching requests while preserving its configuration. The API returns 204 with no body for both operations.- Python SDK
- Go SDK
- curl
Delete a rule
Delete a rule by ID. The operation is irreversible and returns 204 with no body on success.- Python SDK
