Overview

This node interacts with the LINE Messaging API to send multicast messages to multiple users. It supports sending various types of messages including text, image, video, audio, location, sticker, and flex messages. Users can specify a comma-separated list of user IDs (up to 500) to receive the message. The node also supports adding quick reply buttons to messages, which can be configured either via a visual builder or JSON. This node is useful for scenarios where a message needs to be broadcasted to a specific group of users, such as marketing campaigns, notifications, or updates.

Use Case Examples

  1. Sending a text multicast message to multiple users to announce a new product.
  2. Sending an image multicast message with a preview to a group of users for promotional purposes.
  3. Sending a location multicast message to multiple users to share an event venue.
  4. Adding quick reply buttons to a multicast message to gather user feedback or responses.

Troubleshooting

  • Ensure the user IDs list does not exceed 500 users to avoid API errors.
  • Verify that URLs for original content and preview images use HTTPS as required by the API.
  • If sending flex messages, ensure the JSON format of flexContents is valid to prevent parsing errors.
  • When adding quick reply buttons, limit the number of items to 13 to comply with API constraints.
  • Common error messages may include authentication failures, invalid user IDs, or malformed message payloads. Check API credentials and input data for correctness.
