### Result Object Field Details

You can use the result of the action's data as inputs to downstream workflow actions.

Each fetch action requires an object name, which nests the action's result data inside the downstream data context in the workflow. See [Passing Data Between Actions](https://docs.morf.health/docs/knowledge_base/passing_data_between_actions.md) for how to set it and reference the result from downstream nodes.

Here we demonstrate how to refer to this data using the prefix `$result_object_key`.

**AllergySensitivity** `Fetch Action Response Object`

**fields**

**id** `string` *required*

The unique identifier of the allergy sensitivity

```json CEL theme={null}
$result_object_key.id
```
