Overview

The node interacts with the LINE Messaging API to retrieve profile information related to group members. Specifically, the "Get Group Member Profile" operation fetches the profile details of a user who is a member of a specified group in LINE. This can be useful in scenarios where you want to obtain user information such as display name, user ID, or profile picture within a group context.

Practical examples include:

  • Retrieving a group member's profile to personalize messages sent to them.
  • Displaying group member information in dashboards or reports.
  • Automating workflows that depend on group member attributes.

Properties

Name Meaning
User ID The unique identifier of the user whose profile you want to retrieve within the group.
Group ID The unique identifier of the group where the user is a member.

Output

The output JSON contains the profile information of the specified group member. This typically includes fields such as:

  • userId: The user's unique LINE ID.
  • displayName: The display name of the user.
  • pictureUrl: URL to the user's profile picture.
  • Other profile-related metadata provided by the LINE Messaging API.

No binary data output is indicated for this operation.

Dependencies

  • Requires an API key credential for the LINE Messaging API (referred generically as an API key credential).
  • Optionally uses an additional API validation service via a secondary API key credential to validate subscription and access rights.
  • The node depends on the bundled line-api module which abstracts the LINE API calls.
  • Proper configuration of credentials in n8n is necessary for successful execution.

Troubleshooting

  • Invalid Subscription or API Key: If the node throws an error indicating invalid subscription or API key, verify that the API key credential is correctly configured and active.
  • Missing or Incorrect User ID / Group ID: Ensure that the User ID and Group ID inputs are correct and correspond to existing entities in LINE.
  • Permission Issues: The authenticated API key must have permission to access group member profiles; otherwise, the request will fail.
  • Network or API Errors: General HTTP errors from the LINE API should be checked for rate limits, connectivity, or service availability.
