# Setting keys

> Declare Instance keys on the Graph, then insert them into fields.

**Setting keys** on the Graph toolbar lists the keys an Instance should fill. Save the Graph, then publish so the pinned version carries the list.

<h2 id="edit">

**Setting keys** opens the list. **Add key** appends a row. **Save** writes the list into the Graph draft (autosave).

| Field        | What it does                                                                 |
| ------------ | ---------------------------------------------------------------------------- |
| **Key**      | Letters first, then letters, digits, `.`, `_`, `-`. Example: `company.name`. |
| **Type**     | **Text**, **Flag**, or **Number**.                                           |
| **Required** | On, with no **Default**: the operator must set a value before **Go live**.   |
| **Label**    | Name on Instance Settings. Empty uses the key.                               |
| **Default**  | Used on Run when the Instance has no value. **None** means no default.       |

At most 64 keys.

A Cron **Enabled setting key**, [Code](/graph/tools/code) **Settings keys**, and `{{settings:…}}` in a field must use a key from this list. Unknown keys show as a workflow issue.

<h2 id="insert">
  Insert value
</h2>

On a Graph field, **Insert value** includes **Setting keys**. Each row inserts a token like:

```
{{settings:company.name}}
```

The part after `settings:` is the full key, including dots. It is not a path into a JSON object.

[Previous nodes](/graph/previous-nodes#insert) still lists connected node fields. Secrets stay on the same menu when the field allows them.

<h2 id="instance">
  After publish
</h2>

Operators fill the keys on Instance [Settings](/instance/settings#declared). **Workflow keys** follows this list. Required keys without a default appear in **Setup** until they have a value.
