# POST example

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://mchen-ai-models-sync.previews.developers.cloudflare.com/firewall/api/cf-firewall-rules/post/index.md)|[Agent setup](https://mchen-ai-models-sync.previews.developers.cloudflare.com/agent-setup/)

This example creates several firewall rules using a single API call.

Note

To create a firewall rule you need a [filter](https://mchen-ai-models-sync.previews.developers.cloudflare.com/firewall/api/cf-filters/what-is-a-filter/) identifier (`id`). If you have not created a filter yet, refer to the [Cloudflare Filters API documentation](https://mchen-ai-models-sync.previews.developers.cloudflare.com/firewall/api/cf-filters/).

```bash
curl "https://api.cloudflare.com/client/v4/zones/{zone_id}/firewall/rules" \
--header "X-Auth-Email: <EMAIL>" \
--header "X-Auth-Key: <API_KEY>" \
--header "Content-Type: application/json" \
--data '[
  {
    "filter": {
      "id": "<FILTER_ID_1>"
    },
    "action": "allow",

    },
    "action": "allow",

  }

```
