Whatsapp LangGraph Agent Integration is an example implementation showcasing the deployment of LangGraph-based AI agents on WhatsApp messaging. It uses Python and FastAPI to expose webhook endpoints for Twilio’s WhatsApp API, automatically parsing incoming messages into the agent’s graph workflow. The agent supports context preservation across sessions with built-in memory nodes, tool invocation for specific tasks, and dynamic decision-making via LangGraph’s modular nodes. Developers can customize graph definitions, integrate additional external APIs, and manage conversational state seamlessly. This integration acts as a template, illustrating message routing, response generation, error handling, and easy scalability to build complex interactive chatbots on WhatsApp.
