Line Message

Line Message Node

Overview

This node allows sending various types of messages through the Line messaging platform. Specifically, for the "Video" operation, it sends a video message with a specified video URL and a preview image URL. This is useful in scenarios where you want to share video content directly within a chat or conversation on Line, such as promotional videos, tutorials, or personal video messages.

Practical example: A marketing automation workflow that sends a product demo video to users who subscribe to a campaign.

Properties

Name Meaning
URL The direct URL to the video file you want to send. Must be a valid URL pointing to the video content (max 2000 characters).
Preview Url The URL of an image used as a preview thumbnail for the video. This image is shown before the video plays (max 2000 characters).
Tracking ID An optional identifier to track when the recipient finishes watching the video. Useful for analytics or triggering follow-up actions.

Output

The node outputs JSON data structured as follows:

{
  "message": {
    "type": "video",
    "originalContentUrl": "<URL of the video>",
    "previewImageUrl": "<URL of the preview image>"
  }
}
  • type: Always set to "video" for this operation.
  • originalContentUrl: The video URL provided as input.
  • previewImageUrl: The preview image URL provided as input.

No binary data output is generated by this node.

Dependencies

  • Requires an active connection to the Line messaging platform.
  • Needs appropriate API credentials or authentication tokens configured in n8n to send messages via Line.
  • The URLs provided must be accessible and publicly reachable by Line servers to fetch the video and preview image.

Troubleshooting

  • Invalid URL errors: Ensure that both the video URL and preview image URL are correct, publicly accessible, and use supported protocols (e.g., HTTPS).
  • Message not sent: Verify that the API credentials are correctly configured and have permissions to send video messages.
  • Tracking ID not working: If tracking events do not trigger, confirm that the tracking ID is unique and properly handled in your Line account or webhook setup.
  • Payload errors: Make sure the preview image URL is provided when sending a video message, as it is required.
