GET
List a subscription's add-ons
Returns every add-on currently attached to a subscription. Each add-on is an existing plan billed as an extra line — add-on plan price × quantity, taxed independently — on the subscription’s recurring invoices. Attach one with Add Subscription Add-on and detach with Remove Subscription Add-on. The list is not paginated; a subscription with no add-ons returns an empty array.
