# Metadata

> Learn how to work with metadata in Yorlet.

## Configuration

### Data

You can add 50 total key-value pairs within these data limits:

* **key**: 40 character limit. Square brackets (`[` `]`) can’t be included in keys.
* **value**: 500 character limit.

If your system requires more space than this, store your data in your external database and use a key-value pair to store the external object’s `ID` in `metadata`.

If you want to display a single field to customers, explore using `description`.

Metadata isn’t visible to your customers unless you choose to show it.

Never store sensitive information, such as bank account information, to metadata.
