# Update a top-up

Updates the metadata of a top-up. Other top-up details are not editable by design.

## Returns

The newly updated top-up object if the call succeeded. Otherwise, this call raises [an error](https://docs.stripe.com/api/topups/update.md#errors).

## Parameters

- `description` (string, optional)
  An arbitrary string attached to the object. Often useful for displaying to users.

- `metadata` (object, optional)
  Set of [key-value pairs](https://docs.stripe.com/docs/api/metadata.md) that you can attach to an object. This can be useful for storing additional information about the object in a structured format. Individual keys can be unset by posting an empty value to them. All keys can be unset by posting an empty value to `metadata`.
