Page Shield API
You can enable and disable Page Shield, configure its settings, and fetch information about detected scripts and connections using the Page Shield API.
To authenticate API requests you need an API token. For more information on the required API token permissions, refer to Roles and permissions.
You can obtain the complete endpoint by appending the Page Shield API endpoints to the Cloudflare API base URL:
https://api.cloudflare.com/client/v4The {zone_id} argument is the zone ID (a hexadecimal string). You can find this value in the Cloudflare dashboard or using the Cloudflare API’s /zones endpoint.
The {script_id} argument is the script ID (a hexadecimal string). This value is included in the response of the List Page Shield scripts operation for every detected script.
The {connection_id} argument is the connection ID (a hexadecimal string). This value is included in the response of the List Page Shield connections API operation for every detected connection.
The following table summarizes the available operations:
| Operation | Method + URL stub | Notes |
|---|---|---|
| Get Page Shield settings | GET zones/{zone_id}/page_shield | Fetch Page Shield settings (including the status). |
| Update Page Shield settings | PUT zones/{zone_id}/page_shield | Update Page Shield settings. |
| List Page Shield scripts | GET zones/{zone_id}/page_shield/scripts | Fetch a list of detected scripts. |
| Get a Page Shield script | GET zones/{zone_id}/page_shield/scripts/{script_id} | Fetch the details of a script. |
| List Page Shield connections | GET zones/{zone_id}/page_shield/connections | Fetch a list of detected connections. |
| Get a Page Shield connection | GET zones/{zone_id}/page_shield/connections/{connection_id} | Fetch the details of a connection. |
| List Page Shield cookies | GET zones/{zone_id}/page_shield/cookies | Fetch a list of detected cookies. |
| Get a Page Shield cookie | GET zones/{zone_id}/page_shield/cookies/{cookie_id} | Fetch the details of a cookie. |
| List Page Shield policies | GET zones/{zone_id}/page_shield/policies | Fetch a list of all configured CSP policies. |
| Get a Page Shield policy | GET zones/{zone_id}/page_shield/policies/{policy_id} | Fetch the details of a CSP policy. |
| Create a Page Shield policy | POST zones/{zone_id}/page_shield/policies | Creates a CSP policy with the provided configuration. |
| Update a Page Shield policy | PUT zones/{zone_id}/page_shield/policies/{policy_id} | Updates an existing CSP policy. |
| Delete a Page Shield policy | DELETE zones/{zone_id}/page_shield/policies/{policy_id} | Deletes an existing CSP policy. |
The malicious script classification (Malicious or Not malicious) is not directly available in the API. To determine this classification, compare the script’s js_integrity_score value with the classification threshold, which is currently set to 10. Scripts with a score value lower than the threshold are considered malicious.
This example obtains the current settings of Page Shield, including the status (enabled/disabled).

- Scripts hosted in
myapp.example.com(which does not include scripts inexample.com). - Scripts hosted in
cdnjs.cloudflare.com. - The Google Analytics script using its full URL.
- All scripts in the same origin (same HTTP or HTTPS scheme and hostname).
All other scripts would trigger a policy violation, but those scripts would not be blocked.
