Update an invoice's line item ​

Updates an invoice’s line item. Some fields, such as tax_amounts, only live on the invoice line item, so they can only be updated through this endpoint. Other fields, such as amount, live on both the invoice item and the invoice line item, so updates on this endpoint will propagate to the invoice item as well. Updating an invoice’s line item is only possible before the invoice is finalized.

Returns ​

The updated invoice’s line item object is returned upon success. Otherwise, this call raises an error.
