### Structured Data in Zeal

Updateable objects in Zeal, such as Employee Check and Shifts, have a **metadata** parameter. You can use this parameter to attach key-value data to Zeal objects. Metadata is useful for storing additional, structured information on an object.

For instance, you could store your descriptions of jobs in the metadata object of a Zeal Shift object or use the metadata object for correlation IDs so you can parse the response from Zeal.

### Important Notes
- Metadata is not used in any way by Zeal--you may use the metadata object in any way you like.
- However, please do not store any sensitive information as metadata.
- The metadata object can take any JSON type.

### Example Metadata Object

```json
{
  "metadata": {
    "jobID": "19834673",
    "description": "Piecework pay"
  }
}
```
