Customer Feedback Aggregator

Overview

This n8n workflow collects customer feedback from multiple sources — NPS surveys (Typeform), support tickets (Zendesk), and product reviews (G2) — runs sentiment analysis, categorizes by theme, and delivers a weekly summary to your CS team via Slack. It highlights accounts with negative feedback that need immediate attention.

Prerequisites

Before setting up this template, you'll need:

• n8n instance (self-hosted or n8n Cloud)
• Typeform — API token for accessing NPS survey responses
• Zendesk — API credentials for pulling resolved ticket data
• G2 — API access for product reviews (optional — can be removed)
• Slack workspace — Bot token with permission to post to channels

Setup Guide

Step 1: Import the Workflow

1. Open your n8n instance

2. Go to Workflows → Import from File

3. Upload the workflow.json file

Step 2: Configure Credentials

1. Typeform: Add HTTP Header Auth with your Typeform personal access token

2. Zendesk: Add Zendesk API credentials (subdomain + API token)

3. G2: Add HTTP Header Auth with your G2 API token

4. Slack: Configure Slack bot credentials

Step 3: Update API Endpoints

• Fetch NPS Responses — Replace YOUR_FORM_ID with your Typeform form ID
• Fetch Resolved Tickets — Update Zendesk subdomain
• Fetch G2 Reviews — Replace YOUR_PRODUCT_ID with your G2 product ID

Step 4: Customize Sentiment Analysis

Open the Analyze Sentiment code node to adjust:

• Score thresholds for positive/negative classification
• Theme keywords for your product's common feedback topics
• Number of flagged accounts to include in the summary

Step 5: Configure Slack Channel

Update the Post Weekly Summary node with your channel (default: #cs-feedback).

Step 6: Activate

Toggle the workflow to Active.

How to Customize

Add more feedback sources

Add HTTP Request nodes for additional sources like Intercom conversations, Delighted surveys, or Trustpilot reviews. Connect them to the Merge node.

Use AI for sentiment analysis

Replace the keyword-based sentiment analysis with an OpenAI or Claude API call for more nuanced classification and theme extraction.

Add a Google Sheets dashboard

Add a Google Sheets node to write weekly summaries for historical trend tracking.

Route critical feedback immediately

Add an IF node before the weekly summary to detect highly negative feedback (NPS ≤ 3) and send an immediate Slack DM to the assigned CSM.

Troubleshooting

• No Typeform data — Verify your form ID and that the API token has read access
• G2 API errors — G2 API access may require an enterprise plan; remove this node if unavailable
• Empty sentiment results — Check that feedback text is in the expected field names (feedback_text, comment, or description)
• Slack formatting issues — Long feedback snippets may break formatting; adjust the substring length in the code node
