Overview

Unlock Automated, On-Brand Instagram Engagement with this AI Agent

This workflow transforms your n8n instance into a sophisticated AI chat agent for Instagram. It listens for incoming messages via a webhook (easily connected to tools like ManyChat), processes them with an OpenAI-powered LangChain agent, and sends back intelligent, context-aware responses. The agent is designed with conversational memory, allowing it to recall previous messages in the same session for a more natural and human-like interaction. Define your brand's exact persona, voice, and rules with a simple system prompt, and let your AI agent handle the rest.

Key Features & Benefits

  • AI-Driven Conversations: Leverages a LangChain agent with an OpenAI model (like GPT-4) to understand and generate nuanced, relevant replies.
  • Customizable Persona: Easily edit the system prompt to define your agent's personality, tone of voice, and knowledge boundaries, ensuring all responses are perfectly on-brand.
  • Conversational Memory: Remembers the last 20 messages in a conversation, enabling contextual follow-ups and avoiding repetitive interactions.
  • Effortless Integration: Connects to Instagram via any service that can send a webhook, such as ManyChat, to trigger the workflow in real-time.
  • Scalable Engagement: Frees up your team by automating responses to common questions, welcoming new followers, or providing 24/7 first-line support.

Use Cases

  • Automating responses to frequently asked questions in Instagram DMs.
  • Engaging with new followers instantly with a personalized welcome message.
  • Qualifying leads or gathering information from potential customers via chat.
  • Providing 24/7 first-line customer support directly on Instagram.

Prerequisites

  • An n8n instance (Cloud or self-hosted).
  • OpenAI API Key with access to a suitable model (e.g., gpt-3.5-turbo or gpt-4).
  • An Instagram Business account.
  • A third-party gateway tool like ManyChat to capture Instagram messages and trigger a webhook.

Setup Instructions

  1. Import the workflow into your n8n instance.
  2. Configure the 'ChatGPT model' node with your OpenAI API Key and select your desired model.
  3. In the 'Set your system promt for AI' node, customize the prompt variable to define your agent's persona and instructions.
  4. Copy the production webhook URL from the 'Getting message from Instagram' node.
  5. In your gateway tool (e.g., ManyChat), create an action that sends a POST request to the copied webhook URL.
  6. Ensure the request body from your gateway tool sends the user's message and a unique session identifier, mapped to text and session_id respectively.
  7. Activate the workflow and test the connection by sending a DM to your Instagram account.
