The meeting focused on a step-by-step walkthrough of integrating the n8n AI agent with ManyChat, enabling connectivity to Instagram, Facebook, WhatsApp, Telegram, and more.
The discussion covered prerequisites, template imports, webhook configuration, API credentials, and message automation for seamless cross-platform AI responses.
Testing and troubleshooting steps were shown, including real-time conversation handling, multi-message aggregation, and flexible adaptation for other platforms.
Free templates and additional instructional resources were offered through the community site.

Integration Setup Process Overview
To connect n8n AI agent to Instagram or other platforms, ManyChat is used as an intermediary, providing automation across several messaging platforms.
n8n (workflow builder and AI agent creator) and ManyChat (multi-platform, originally for Instagram) accounts must be set up and connected.
Templates for both services are supplied for free via the community, allowing for simplified import and setup.
n8n Configuration
Download and import the provided n8n template.
The template includes a webhook node (triggered by ManyChat), an OpenAI-connected AI agent node (with prompt and credential setup), a window buffer memory node (context window length set to 10), and a respond-webhook node.
Credentials for OpenAI API must be created and saved.
System prompts for the AI agent can be customized or use templates as provided.
ManyChat Template and Google Apps Script
The ManyChat template includes a message counter system to combine multiple quick user messages into one reply.
Time delay for message aggregation is adjustable (10 seconds default in demo, recommended 30-60 seconds).
A Google Apps Script is used to process and format messages before sending API requests to n8n.
The tutorial for setting up Google Apps Script is available in the community.
Webhook Linking and Testing
In n8n, ensure the webhook is set to POST, activate 'listen for test event,' and copy the test URL.
In ManyChat, initiate a test contact by direct messaging yourself on the connected Instagram account.
Test the integration by sending messages, ensuring n8n receives and processes them, and ManyChat relays the AI response back to the user.
Production Setup and Automation
After successful testing, switch the webhook to the production URL and update the ManyChat template accordingly.
Review and set automation defaults: assign the new flow as the default reply for every user message (not just once per 24 hours).
Multi-Platform Adaptation
The same ManyChat template and n8n workflow can be duplicated and adapted for Facebook Messenger or other supported channels by changing connection settings and flow assignments.
Decisions
Default reply frequency set to "every time" — To ensure the AI agent responds to each Instagram message, not just one per 24-hour period.
