messenger_room_product_apply

# messenger_room_product_apply

Create or update a paid group room's individual product in the Messenger app (pApp D00003). Requires confirmation SAVE_ROOM_INDIVIDUAL_PRODUCT, name, selling/original price in the channel currency, period, availability and CASH_ONLY or CASH_AND_CP. Write: saves the product, then links it to the room; the product can become purchasable before the link completes. A lost receipt stays pending and is never resent; task_resume only observes, and prepared work needs the identical apply. Called without confirmToken it previews and returns a confirmToken; repeating the same input with it executes once.
