Configuration

4 fields, 1 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.

Field	Type	Required	Default	Constraints	Example
to The userId values to send to, at most 500; LINE IDs from the app do not work.	array	Yes	—	1–500 characters; array of string	["U4af4980629abcdef1234567890abcdef"]
text The message to send, as plain text; this is the shortcut for a single text message.	string	No	—	—	Hello, world
messages Full LINE message objects (sticker, image, Flex…), 1 to 5 of them; use this instead of 'text'.	array	No	—	1–5 characters; array of object	[{"text":"Hello, world","type":"text"}]
notification_disabled Deliver the message without a push notification or sound on the user's device.	boolean	No	false	—	—

At least one of text, messages must be set.

  "messages": [
    {
      "text": "Hello, world",
      "type": "text"
    }
  ],
  "notification_disabled": false,
  "text": "Hello, world",
  "to": [

  ]
}
