# Update Card Data

> Update expiration dates and creator references on stored card tokens without re-tokenizing.

## Update Expiration Date

When a cardholder's card is renewed with a new expiration date, update the token via the [Update Expiration](/api-reference/manage-tokens/update-expiration) endpoint rather than creating a new one. This keeps the same token in use across your system.

## Update Creator Reference

The **creator reference** is your internal identifier for the token. It can be a booking ID, customer number, or any string meaningful to your system. You can update it at any time via the [Update Creator Reference](/api-reference/manage-tokens/update-creator-reference) endpoint.

## Delete Creator Reference

Remove the creator reference from a token without deleting the token itself via the [Delete Creator Reference](/api-reference/manage-tokens/delete-creator-reference) endpoint.

## When to Update vs. Create New

* **Same card, new expiry**. Update the existing token.
* **Different card number**. Create a new token (the card number cannot be changed on an existing token).
* **Changed reference**. Update the creator reference.
