# `Stripe.Params.InvoiceUpdateLinesParams`
[🔗](https://github.com/jeffhuen/tiger_stripe/blob/main/lib/stripe/params/invoice_update_lines_params.ex#L2)

Parameters for invoice update lines.

# `t`

```elixir
@type t() :: %Stripe.Params.InvoiceUpdateLinesParams{
  expand: [String.t()] | nil,
  invoice_metadata: map() | nil,
  lines: [map()]
}
```

* `expand` - Specifies which fields in the response should be expanded.
* `invoice_metadata` - Set of [key-value pairs](https://docs.stripe.com/api/metadata) 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`. For [type=subscription](https://docs.stripe.com/api/invoices/line_item#invoice_line_item_object-type) line items, the incoming metadata specified on the request is directly used to set this value, in contrast to [type=invoiceitem](https://docs.stripe.com/api/invoices/line_item#invoice_line_item_object-type) line items, where any existing metadata on the invoice line is merged with the incoming data.
* `lines` - The line items to update.
