When you create, cancel, or modify a subscription, you can now pass Include-Changed-Resources: issued_immediately to return only the invoices that are payable right away, along with any voided invoices and credit note changes. You get the changes you need to act on now without waiting for the full set of future-dated invoices.

• The header now also accepts all to return every changed resource, equivalent to the previous true value.
• issued_immediately is a more complete alternative to payable_invoices. Note that payable_invoices will be deprecated in favor of issued_immediately.
