This n8n workflow creates an intelligent chatbot that integrates LINE messaging, Google Calendar, and Gmail to enhance user interaction and automate scheduling tasks. The process begins with a webhook that receives messages from LINE users. The message content is processed through AI nodes, including OpenAI models, to understand the user’s intent and generate appropriate responses.
The workflow employs memory buffer nodes to maintain context during conversations, facilitating coherent and context-aware responses. If the message type is text, it is cleansed of markdown and tags for clarity. The AI agent, powered by LangChain and OpenAI, interprets the message, fetches relevant information from Wikipedia if needed, and generates a suitable reply.
In case of scheduling requests, the workflow accesses Google Calendar to read upcoming events and create new ones based on the AI’s interpretation of user commands. Gmail is used to retrieve emails received within specified dates, providing additional context or information.
The workflow ensures smooth communication with the LINE user, handling different message types and responses, whether simple replies or complex scheduling actions. Error handling nodes manage unexpected or unsupported message types, replying with a friendly prompt to the user.
Practical use cases include customer support automation, meeting scheduling, information retrieval, and enhancing user engagement through AI-driven insights and actions directly within LINE, integrated seamlessly with Google services.
