# Custom Features
You can add the following features on your LINE MINI App to further enhance user experience.
# Service Messages
Service messages can be used if you want to send users the confirmation of their restaurant or accommodation reservations.
A service message is a feature whereby LINE MINI App notifies the user of information the user should know regarding the user's request.
Service messages sent from LINE MINI Apps are displayed in the LINE "Service Messages" talkroom, regardless of the type of LINE MINI App.
To send a service message, use the service message API. For details, see Sending service messages.
You are allowed to send service messages only as a confirmation or response to a user action. Advertisements and event notifications are prohibited, including information on discounts, shopping rewards, new products, discount coupons or promotions. For more information about the service message conditions, see Conditions for service messages.

Examples of proper usage of user data include but are not limited to:
- Automatically entering contact information such as sender, phone number, address, etc. to save the effort of entering the same information each time.
- Recommending the right products according to the user's gender, birthday, etc.
