# PUT examples

## Update multiple rules

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

You can include up to 25 rules in the JSON object array (`-d` flag) to update as a batch. The batch is handled as a transaction.

Request

```
curl --request PUT \"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 '[  {    "id": "<RULE_ID>",    "paused": false,    "description": "Challenge site",    "action": "challenge",    "priority": null,    "filter": {      "id": "<FILTER_ID>",      "expression": "not http.request.uri.path matches \"^/api/.*$\"",      "paused": false,      "description": "not /api"    }  }]'
```

Note

`PUT` does not update the filter specified. It only looks at the filter ID (`<FILTER_ID>`) to update the rule with a new filter.

To update the filter, use the [Filters API](https://developers.cloudflare.com/firewall/api/cf-filters/).

Response

```
{  "result": [    {      "id": "<RULE_ID>",      "paused": false,      "description": "Challenge site",      "action": "challenge",      "priority": null,      "filter": {        "id": "<FILTER_ID>",        "expression": "not http.request.uri.path matches \"^/api/.*$\"",        "paused": false,        "description": "not /api"      }    }  ],  "success": true,  "errors": [],  "messages": []}
```

## Update a single rule

This example updates the firewall rule with ID `{rule_id}`.

You must include the following fields in the request body:

* `id`
* `action`
* `filter.id`

All other fields are optional.

Request

```
curl --request PUT \"https://api.cloudflare.com/client/v4/zones/{zone_id}/firewall/rules/{rule_id}" \--header "X-Auth-Email: <EMAIL>" \--header "X-Auth-Key: <API_KEY>" \--header "Content-Type: application/json" \--data '{  "id": "<RULE_ID>",  "paused": false,  "description": "Do not challenge login from office IPv6",  "action": "allow",  "priority": null,  "filter": {    "id": "<FILTER_ID>",    "expression": "ip.src in {2400:cb00::/32 2803:f800::/32 2c0f:f248::/32 2a06:98c0::/29} and (http.request.uri.path ~ \"^.*/wp-login.php$\" or http.request.uri.path ~ \"^.*/xmlrpc.php$\")",    "paused": false,    "description": "Login from office"  }}'
```

Response

```
{  "result": {    "id": "<RULE_ID>",    "paused": false,    "description": "Do not challenge login from office IPv6",    "action": "allow",    "priority": null,    "filter": {      "id": "<FILTER_ID>",      "expression": "ip.src in {2400:cb00::/32 2803:f800::/32 2c0f:f248::/32 2a06:98c0::/29} and (http.request.uri.path ~ \"^.*/wp-login.php$\" or http.request.uri.path ~ \"^.*/xmlrpc.php$\")",      "paused": false,      "description": "Login from office"    }  },  "success": true,  "errors": [],  "messages": []}
```

Note

`PUT` overwrites fields that are not explicitly passed in the request.

For example, if the request omits `description`, any previously existing `description` value will be erased.

To preserve existing values, issue a `GET` request and based on the response, determine which fields (and respective values) to include in your `PUT` request.
