This workflow integrates LINE messaging with Google Sheets and AI to enable users to search for files easily. When a user sends a message on LINE, the workflow activates via a webhook, captures the message, and uses an AI agent to extract a filename from the user’s text. The workflow then searches a Google Sheets document for the filename and replies with the file URL if found, or indicates if the file is not available. This automation streamlines file retrieval directly from LINE, making it useful for customer support, document sharing, or internal file management.
