# POST example

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

Note

To create a firewall rule you need a [filter](https://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://developers.cloudflare.com/firewall/api/cf-filters/).

Request

```
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",    "description": "Do not challenge login from office"  },  {    "filter": {      "id": "<FILTER_ID_2>"    },    "action": "challenge",    "description": "Challenge login"  },  {    "filter": {      "id": "<FILTER_ID_3>"    },    "action": "js_challenge",    "description": "Non-interactive challenge site"  },  {    "filter": {      "id": "<FILTER_ID_4>"    },    "action": "allow",    "description": "Allow API traffic without challenge"  }]'
```
