# Manage rules via the APIs

Last updated Aug 24, 2026|Copy as Markdown| [View as Markdown](https://0f4bf0fb.previews.developers.cloudflare.com/firewall/api/index.md)| [Agent setup](https://0f4bf0fb.previews.developers.cloudflare.com/agent-setup/)

Cloudflare offers APIs that work together to achieve the same effect as the UI-based **Firewall rules** feature under **Security** > **WAF**.

Deprecation notice

Cloudflare Firewall Rules has been deprecated. Cloudflare has moved existing firewall rules to [WAF custom rules](https://0f4bf0fb.previews.developers.cloudflare.com/waf/custom-rules/). For more information on this change, refer to the [upgrade guide](https://0f4bf0fb.previews.developers.cloudflare.com/waf/reference/legacy/firewall-rules-upgrade/).

These APIs are the following:

- [**Firewall Rules API**](https://0f4bf0fb.previews.developers.cloudflare.com/firewall/api/cf-firewall-rules/): Manage firewall rules and their actions, based on criteria separately defined through filters.
- [**Filters API**](https://0f4bf0fb.previews.developers.cloudflare.com/firewall/api/cf-filters/): Manage the filters that enable rule matching.
- [**Lists API**](https://0f4bf0fb.previews.developers.cloudflare.com/waf/tools/lists/lists-api/): Manage named lists of items (such as IP addresses) that you can use in the rules of different Cloudflare products.
