# Retrieve Data

:retrieve-data-lg:

The `Retrieve Data` task in conjunction with the `Store Data` task provides a way to share common cache between workflow pages. A stored value can be retrieved using a unique identifier that matches the one specified in the `Store Data` task.

## Inputs

| Name     | Data Type | Description         |
|----------|-----------|---------------------|
| Activate | `any`     | Retrieve all values |

## Outputs

| Name            | Data Type  | Description                                            |
|-----------------|------------|--------------------------------------------------------|
| `<custom list>` | `<custom>` | Retrieved cached value                                 |
| Success         | `Boolean`  | `true` value emitted when the values are retrieved     |
| Error           | `Error`    | Error that occurred during the processing of this task |

## Settings

In the **General** tab, you have the usual settings and the following setting:

| Name             | Data Type | Default | Description                                                      |
|------------------|-----------|---------|------------------------------------------------------------------|
| Trigger on Store | `Boolean` | false   | When `true`, the task will emit the values when they are changed |
| Emit in new context |  `Boolean`  | false  | When `true`, the emitted value will be wrapped around a new execution context |

In the **Outputs** tab, you have the usual settings and the following setting:

| Name            | Data Type                                                    | Default         | Description                                    |
| --------------- | ------------------------------------------------------------ | --------------- | ---------------------------------------------- |
| Name            | `String`                                                     | "Not specified" | Output value Name                              |
| Identifier      | `String`                                                     |                 | Identifier that will match with the store data |
| Type            | `Long`<br />`Decimal`<br />`DateTime`<br />`Boolean`<br />`String`<br />`Integer` |                 | The Output value type                          |
| Collection Type | `None`<br />`Array`<br />`Map`                               |                 |                                                |
| Default Value   | `any`                                                        |                 | The Output value, default value.               |

## Behavior

This task retrieves a cached value by matching its identifier with data stored by the Store Data task. If a match is found, the value is retrieved; otherwise, the default value is emitted.

## Remarks

Combining `Store` + `Retrieve` (with Trigger `OnStore`) can be used to transfer data between different workflows. This is known as a wormhole and is strongly discouraged. Please use Sub Workflows to implement this kind of behavior.

This task uses a specific structure of context-based data called `zone`. More information on this topic can be read in the [Zones](../../../zones.md) page.
