# Actions

## Overview

Actions define what transformation(s) will be applied to a Tile or an Asset-based upon the defined conditions specified in the Trigger being met.

## Operations

Nosto's UGC Automation Rules support two operations when defining an Action. These operations define whether the transformation value is appended to an existing array or if it overwrites the particular field.

These operations can be utilized when defining Rules via the [**Rules API**](https://github.com/Stackla/docs/blob/master/automation/api/README.md)

| Operator  | Description                            |
| --------- | -------------------------------------- |
| $addToSet | Add element to the Array.              |
| $set      | Overwrite the select field with Value. |

## Fields

Automation Rules currently only support transforming a limited number of fields on both Tiles and Assets. Note: Not all fields can support all available operations, please consider this when building your Automation Rules via the [**Rules API**](https://github.com/Stackla/docs/blob/master/automation/api/README.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nosto.com/ugc/enterprise/automation/actions.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
