This n8n template uses a Telegram chatbot to conduct a Product Satisfaction Survey and fetches questions and stores answers in a Google sheet. It augments an AI Agent to ask follow-up questions to engage the user and uncover more insights in their responses.

This template is intended to demonstrate how you'd realistically approach a workflow where there is structured conversation (static questions) but you still want to include an free-form element (follow-up questions) which can only be accomplished via AI.

Check out an example Survey results: https://docs.google.com/spreadsheets/d/e/2PACX-1vQWcREg75CzbZd8loVI12s-DzSTj3NE_02cOCpAh7umj0urazzYCfzPpYvvh7jqICWZteDTALzBO46i/pubhtml?gid=0&single=true

How it works

A chat session is started with the user who needs to enter the bot command "/next" to start the survey.
Once started, the template pulls in questions from a google sheet to ask the user. Questions are asked in sequence from left column to right column.
When the user answers the question, a text classifier node is used to determine if a follow-up question could be asked.
If so, a mini conversation is initiated by the AI agent to get more details.
If not, the survey proceeds to the next question.
All answers and mini-conversations are recorded in the Google Sheet under the respective question.
When all questions are answered, the template will stop the survey and give the user a chance to restart.

How to use

You'll need to setup a Telegram bot (see docs)
Create a google sheet with an ID column. Populate the rest of the columns with your survey questions (see sample)
Ensure you have a Redis instance to capture state. Either self-host or sign-up to Upstash for a free account.
Update the "Set Variable" node with your google sheet ID and survey title.
Share your bot to allow others to participate in your survey.

Requirements

Telegram for Chatbot
Google Sheets for Survey questions and answers
Redis for State Management and Chat Memory
Community+ license and above for Execution data node - you can remove this node if you don't have this licence.

Customising this workflow

Not using Telegram? This template technically works with other chat apps such as Whatsapp, wechat and even n8n's hosted chat!
This state management pattern can also be applied to other use-cases and scenarios. Try it for other types of surveys!

Create Product Satisfaction Surveys with Telegram, Google Sheets, and AI

This n8n workflow automates the process of collecting product satisfaction feedback through a Telegram bot, classifying the feedback using AI, and storing it in a Google Sheet. It allows for a conversational and intelligent survey experience.

What it does

Listens for Telegram Messages: The workflow is triggered by incoming messages to a configured Telegram bot.
Initial Message Check: It checks if the incoming message is an initial "Start" command or a new survey response.
Manages Chat Memory: It utilizes Redis to manage the conversation history with each user, allowing the AI to maintain context.
Generates AI Responses: If a new survey is initiated, it uses an OpenAI Chat Model to generate a welcome message and the first survey question. If a response is received, it uses an AI Agent to process the user's input and generate follow-up questions or acknowledgements.
Classifies Feedback with AI: It employs a Text Classifier to categorize the user's feedback (e.g., positive, negative, suggestion).
Stores Data in Google Sheets: The classified feedback, along with the user's Telegram ID and the full conversation, is appended as a new row in a specified Google Sheet.
Sends Telegram Responses: Based on AI-generated content or predefined messages, it sends appropriate replies back to the user via Telegram.

Prerequisites/Requirements

n8n Instance: A running n8n instance.
Telegram Bot: A Telegram bot token and the chat ID where the bot will operate.
OpenAI API Key: An API key for OpenAI to use its chat model and AI agent capabilities.
Google Sheets Account: Access to a Google Sheets document where survey responses will be stored.
Redis Instance: A Redis server for storing chat memory.
n8n Langchain Nodes: Ensure the @n8n/n8n-nodes-langchain package is installed in your n8n instance for AI functionalities.

Setup/Usage

Import the Workflow: Download the provided JSON and import it into your n8n instance.
Configure Credentials:
- Telegram Trigger & Telegram Node: Set up your Telegram Bot API credentials.
- Google Sheets Node: Configure your Google Sheets API credentials.
- OpenAI Chat Model & AI Agent Nodes: Provide your OpenAI API Key.
- Redis Chat Memory & Redis Nodes: Configure your Redis connection details.
Google Sheets Setup: Create a new Google Sheet with appropriate column headers (e.g., Telegram ID, Feedback, Classification, Conversation History). Update the "Google Sheets" node to point to your new spreadsheet and sheet name.
Activate the Workflow: Once all credentials are set and configurations are updated, activate the workflow.
Start Survey: Users can initiate the survey by sending a message (e.g., "Start Survey") to your Telegram bot. The AI will then guide them through the feedback process.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
