# Tokens

> Define the tokens that custom campaigns, webinars, and folders can assign values to.

The **Tokens** settings page is where you manage the tokens available to custom campaigns, webinars, and folders. Tokens defined here act as templates: each campaign, webinar, or folder can then [assign its own value](/product-docs/campaigns/tokens) to a token, and every asset inside references the value automatically.

## Creating a token

Click **New** and fill in:

| Field     | Description                                                                                                                                                                                                |
| --------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Label** | A human-readable name for the token (for example, *Event Date*).                                                                                                                                           |
| **Key**   | A unique identifier used to reference the token in assets (for example, `event_date`). If you leave it blank, Conversion generates one from the label. Keys may contain letters, numbers, and underscores. |
| **Type**  | The data type of the token's value.                                                                                                                                                                        |

### Supported token types

| Type              | Description                  |
| ----------------- | ---------------------------- |
| **String**        | Free-form text.              |
| **Number**        | Numeric values.              |
| **Boolean**       | True or false.               |
| **Date**          | A calendar date.             |
| **Date and time** | A date with a specific time. |
| **URL**           | A web address.               |
| **Phone number**  | A phone number.              |

## Managing tokens

Tokens are listed alphabetically by label with their key and type. Use the search box to filter by label or key. From a token's options menu you can:

* **Edit** the label. Keys and types can't be changed after creation.
* **Delete** the token. The dialog lists any assets that reference the token; click the count to review them. Type the token's key to confirm.

<Warning>
  Deleting a token cannot be undone. Any asset that still references the token will treat the reference as invalid, so update those assets first.
</Warning>

## How tokens are used

Once a token is defined here, it becomes available inside every custom campaign, webinar, and folder. Team members can then:

1. Navigate to the campaign's **Tokens** tab.
2. Select the token and assign a value specific to that campaign.
3. Reference the token in any asset within the campaign with Liquid, for example `{{ tokens.event_date }}`. The value populates automatically.

See [Campaign Tokens](/product-docs/campaigns/tokens) for details on assigning and managing token values within a campaign.
