LINE Notification Messages

Do not answer LINE Notification Messages questions from memory — LINE updates APIs frequently and training data is unreliable. Always consult the references below.

LINE Notification Messages allow sending messages to users by specifying their phone number (SHA256-hashed E.164 format), even if they haven't added the LINE Official Account as a friend. Corporate-only service available in Japan, Thailand, and Taiwan. Not for advertising or commercial purposes.

Workflow

Build

1. Read references/api-common.md (rate limits, forward compatibility, error handling)
2. Load the relevant reference for the feature being implemented
3. For architecture or design choices, consult references/experts.md for directional guidance
4. Write code following specs and constraints from references
