# messenger_app_products_apply

Create or edit one app unlock product in the Messenger app (pApp D00003). Create (CREATE_MESSENGER_APP_PRODUCT): name 4–20, presentationalName, KRW 300–100,000,000 in steps of 100 or USD 5–100,000, period 1/3/7/15/30/60/90/180/365 days, private state, CASH_ONLY or CASH_AND_CP. Edit (CHANGE_MESSENGER_APP_PRODUCT): presentationalName, private state, original price and purchase methods only. Write; no deletion exists. CASH_AND_CP needs point branding. After a creation the selling price and access period cannot be changed (the original edit screen has no such fields). 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. Ask the user again before executing; this cannot be undone. When the preview has requiresReconfirmation, execute only with irreversibleConfirmed: true after the person confirms again.
