Reference for LINE Notification Messages — phone-number-based messaging to non-friends, template type (premade layouts) and flexible type (custom Flex Message), delivery completion webhooks, user consent flow, SMS authentication, and billing. Use when the user asks to "send a notification message via phone number", "hash a phone number for PNP", "handle delivery completion webhook", "set up template or flexible notification", "check notification message count", or mentions LINE notification messages, PNP push, phone-number-based delivery, hashed phone number, notification template, delivery completion event, consent states, or SMS authentication for notifications. Always use this skill whenever the user mentions LINE notification messages, PNP, or phone-based LINE messaging to non-friends, even if they don't explicitly say "notification message".
