# Image SFW

## Overview

Safe for Work (SFW) is one of the intelligence services of the Filestack platform. This feature shows you whether the uploaded file contains any unsafe content, or it is safe for your business.

## Processing API

Safe for Work is available as a synchronous operation in the Processing API using the following task:

`sfw`

To use this task in Processing API, you have to use security policy and signature. Read more about security policies [here](https://www.filestack.com/docs/security/policies/).

### Response

- If the uploaded file **is** safe:

```
    {
    "sfw": true
    }
    ```

- If the uploaded file **is not** safe:

```
    {
    "sfw": false
    }
    ```

### Response Parameters

|     |     |     |
| --- | --- | --- |
| **sfw** | [boolean](https://www.filestack.com/docs/transformations/intelligence/sfw/#color-options) | Indicates whether your uploaded file is safe or not. |

### Examples

- Get the safety information of your uploaded file:

```
    https://cdn.filestackcontent.com/security=p:<POLICY>,s:<SIGNATURE>/sfw/<HANDLE>
    ```

- Use sfw in a chain with other tasks such as tagging:

```
    https://cdn.filestackcontent.com/security=p:<POLICY>,s:<SIGNATURE>/tags/sfw/<HANDLE>
    ```

- Use sfw with an external URL:

```
    https://cdn.filestackcontent.com/<FILESTACK_API_KEY>/security=p:<POLICY>,s:<SIGNATURE>/sfw/<EXTERNAL_URL>
    ```

- Use sfw with [Storage Aliases](https://www.filestack.com/docs/delivery/storage_aliases/):

```
    https://cdn.filestackcontent.com/<FILESTACK_API_KEY>/security=p:<POLICY>,s:<SIGNATURE>/sfw/src://<STORAGE_ALIAS>/<PATH_TO_FILE>
    ```

## Workflows Task Configuration

In order to learn how you can use Workflows UI to configure tasks and logic items, please visit [Creating Workflows Tutorial](https://www.filestack.com/docs/tutorials/create-workflow/).

Safe for Work task is available in [Intelligence](https://www.filestack.com/docs/workflows/overview/#tasks) tasks category.

### Workflows Parameters

|     |     |     |
| --- | --- | --- |
| **Task Name** | [string](https://www.filestack.com/docs/transformations/intelligence/sfw/#color-options) | Unique name of the task. It will be included in the webhook response and can be used to build [logic](https://www.filestack.com/docs/transformations/intelligence/sfw/#logic) below. |

## Logic

Safe for Work task returns following response to the workflow:

```
{
  "data": {
    "sfw": false
  }
}
```

or

```
{
  "data": {
    "sfw": true
  }
}
```

### Logic Parameters

|     |     |     |
| --- | --- | --- |
| **data** | [dictionary](https://www.filestack.com/docs/transformations/intelligence/sfw/#color-options) | Includes the information of safe for work task. |
| **sfw** | [boolean](https://www.filestack.com/docs/transformations/intelligence/sfw/#color-options) | Indicates whether the file is safe for work or not. |

Considering the response from the task, you can build [logic](https://www.filestack.com/docs/workflows/overview/#logic) in order to make independent flows with different executing tasks. For example, if you would like to run another task if the file is not safe, you can use following rule:

`sfw eq false`or`sfw neq true`

## Webhook
