## Introduction
User feedback is invaluable for product teams looking to improve their offerings and enhance user satisfaction. Community forums serve as a rich source of organic feedback, feature requests, and bug reports. However, manually sifting through forums to collect and log this feedback into internal tools or tracking systems is time-consuming and error-prone.
In this guide, we will walk through how to build an automated workflow using the powerful open-source automation tool **n8n**. This workflow will monitor a community forum (for example, powered by Discourse or a similar platform), fetch new posts containing user feedback, and log them in a centralized Google Sheets document for easy tracking and analysis.
This automation benefits **product managers**, **community managers**, and **automation engineers** by reducing manual work, improving feedback traceability, and enabling faster action on user inputs.

## Tools and Services Integrated
– **n8n**: An extendable workflow automation tool that will orchestrate the entire process.
– **Community Forum API** (e.g., Discourse REST API): To fetch new posts or topics containing feedback.
– **Google Sheets**: A shared, collaborative spreadsheet where feedback is logged and tracked.
– *(Optional)* **Slack or Email**: For alerting the product team about new important feedback.

## Overview of the Workflow
1. **Trigger:** Scheduled polling every 15 minutes to fetch new posts from the community forum via its API.
2. **Filter:** Identify which posts are relevant user feedback (e.g., based on tags, categories, keywords).
3. **Process:** Extract relevant post details—author, content, timestamp, URL.
4. **Append:** Add the extracted data as new rows in Google Sheets.
5. **Notify (Optional):** Send alerts to Slack or email if the feedback meets certain criteria (e.g., marked urgent or has many likes).

## Step-by-Step Technical Tutorial
### Prerequisites
– An n8n instance running (self-hosted or cloud).
– Access to your community forum’s API credentials (API key, username).
– Google account with a Google Sheet prepared for the feedback log.
– (Optional) Slack workspace and webhook or email SMTP details.
### Step 1: Set Up the Google Sheet
Create a Google Sheet with the following columns:
| Timestamp | Post ID | Author | Category/Tag | Content Summary | URL |
|———–|———|——–|————–|—————–|—–|
– Share this sheet with the Google service account email you’ll use in n8n or with your user account credentials.
– Note the Sheet ID (found in the URL) — you’ll need it later.
### Step 2: Configure n8n Credentials
– In n8n, set up credentials for:
– Google Sheets API (OAuth2 or service account credentials).
– If applicable, Slack Webhook or SMTP server credentials.
### Step 3: Create the n8n Workflow
Open n8n and create a new workflow.
#### Node 1: Cron Trigger
– Configure this node to run every 15 minutes (or other required interval).
#### Node 2: HTTP Request – Fetch New Forum Posts
– Method: GET
– URL: Use your forum API endpoint for recent posts or topics, e.g., `https://forum.example.com/api/latest.json` or `/posts.json`.
– Authentication: Pass API Key and necessary headers.
– Query parameters to limit posts to those newer than last run time (store last run time in workflow data or via an external database/file for incremental fetching).
**Tip:** Use a timestamp filter such as `created_after` if supported by the API to reduce data volume.
#### Node 3: Set Node (Optional but Recommended)
– Purpose: Parse and normalize the dataset from the API response.
– Use JavaScript within Set or Function node to extract relevant fields:
– Post ID
– Author Username
– Creation Date and Time
– Post Content
– Category or Tags
– URL to the post
#### Node 4: IF Node – Filter Relevant Feedback
– Implement logic to filter out non-feedback posts.
– Examples of filtering criteria:
– Posts tagged with `feedback`, `bug`, or `feature-request`.
– Posts containing certain keywords like “issue”, “problem”, or “request”.
This step ensures only meaningful feedback is logged.
#### Node 5: Google Sheets – Append Row
– Operation: Append a new row
– Spreadsheet ID: Your Google Sheet’s ID
– Sheet Name: The correct tab
– Map data fields to corresponding columns:
– `Timestamp` → Post creation date
– `Post ID` → Unique post identifier
– `Author` → Post author
– `Category/Tag` → Feedback type or category
– `Content Summary` → Short excerpt or full content
– `URL` → Link to the forum post
#### Node 6: (Optional) Slack or Email Notification
– Configure this node to send a message or email when feedback meets extra conditions.
– For instance, notify the team if a post has more than 10 likes or a `priority` tag.
### Step 4: Handle State and Incremental Fetching
– To avoid duplicate logging, store the timestamp or ID of the last processed post. Options:
– Use n8n’s “Workflow Data” or a separate Google Sheet tab to save the last run timestamp.
– Pass this timestamp as a parameter in the HTTP Request node to fetch only newer posts.
### Step 5: Test the Workflow
– Manually trigger the workflow to test.
– Verify that new feedback posts appear in Google Sheets.
– Check notifications if configured.
### Step 6: Activate and Monitor
– Activate the workflow.
– Monitor its executions for errors and fine-tune queries or filters as needed.

## Common Errors and Robustness Tips
– **API Rate Limits:** Forums might restrict API calls; respect rate limits and optimize polling frequency.
– **Authentication Failures:** Ensure API keys and OAuth tokens are up-to-date.
– **Data Inconsistency:** Validate data fields before writing to Google Sheets to avoid broken rows.
– **Duplicates:** Properly maintain state to prevent duplicates.
– **Keyword Filtering:** Review and refine keywords or tags periodically to capture relevant feedback without noise.

## How to Adapt and Scale This Workflow
– **Multi-Forum Support:** Add multiple HTTP Request nodes for different community platforms.
– **Sentiment Analysis:** Integrate NLP services (e.g., Google Natural Language, OpenAI) to analyze sentiment or categorize feedback.
– **Ticketing Integration:** Extend the workflow to automatically create issues in Jira, GitHub, or Zendesk.
– **Dashboard Reporting:** Connect Google Sheets data to BI tools for analytics.
– **Real-Time Alerts:** Switch to webhook triggers if supported by forum software for near real-time processing.

## Summary
Automating the logging of user feedback from community forums using n8n streamlines product management workflows, enhances data accuracy, and accelerates response times to user input. This tutorial covered a full practical example integrating forum API data, filtering relevant posts, logging feedback in Google Sheets, and optionally alerting teams. By leveraging the flexibility of n8n and API-driven platforms, teams can efficiently scale feedback management with minimal manual overhead.

## Bonus Tip
To make your workflow even more effective, consider implementing an **auto-tagging system** using keyword matching or machine learning to categorize feedback automatically. This will help product teams prioritize issues faster and allocate resources more efficiently.
