Update the number of line items in a recurring invoice. You can also update other recurring invoice details.

You can use the PUT operation to add, remove, or replace the number of line items in a recurring invoice. A set of rules apply with the PUT operation.

• When you add a new line item, a new line item id is generated in the invoice.
• When you omit an existing line item id, the line item is removed from the invoice.

When a recurring invoice is modified, all future invoices are automatically changed.
