The LINE channel supports push via phone number notification messages. This kind of message can only be sent from LINE Official Accounts created in Japan, Thailand, or Taiwan.
These messages can only be used for important notifications. For example, they can be used for delivery updates, payment receipts, and reservation confirmations. They can't be used for marketing purposes.
There are two types of notification messages supported on the LINE channel: template notification messages and flexible notification.
Notification Messages (template) are supported through the channel_specific_message feature of Sinch's Conversation API. Detailed API documentation can be found in the API reference guide.
Template messages have a predefined structure consisting of title, description, items, and buttons. Each of these elements is predefined and unique for Japan, Thailand, and Taiwan.
Specifying a template key results in a predefined title and description being displayed at the top of the message.
See our LINE documentation for more details and available templates.
Each template can contain one large 'emphasized' item and multiple smaller items. An item consists of a predefined label and a custom value.
See our LINE documentation for more details and available items.
Each template can contain multiple buttons. A button consists of a predefined label and a custom URL.
See our LINE documentation for more details and available buttons.
Notification Messages (flexible) do not have a separate message type in Sinch's Conversation API. They may be any message type, but they must conform to an approved template. To get approval, you must:
- Contact your account manager to purchase LINE Official Notification Messages.
- Complete and return a template approval form, which will be provided to you.
- Send only approved message content to the end user using Sinch's Conversation API.
