### Introduction
Product teams in startups and scale-ups rely heavily on feature usage data to make informed decisions about development priorities, user engagement, and product improvements. Traditionally, generating feature usage reports involves manual aggregation and analysis of data from various sources such as analytics platforms, databases, and CRM systems. This process can be time-consuming, error-prone, and slow, hindering quick iterations and timely insights.
Automating feature usage reports ensures that product managers and engineers have up-to-date, accurate data without manual effort. This guide demonstrates how to build an end-to-end automation workflow using n8n — an open-source no-code/low-code automation tool — to generate and deliver feature usage reports automatically.
### Use Case Overview
– **Problem:** Manual feature usage report generation is inefficient and delays insight delivery.
– **Beneficiaries:** Product managers, data analysts, and engineering leads.
– **Goal:** Automate the collection, aggregation, formatting, and distribution of feature usage reports on a daily or weekly basis.
### Tools and Integrations
– **n8n:** The core automation engine.
– **Google Analytics or Segment:** For feature usage event data. (We’ll use Google Analytics API here as an example.)
– **Google Sheets:** To aggregate and store the usage data in a structured format.
– **Slack or Email:** To distribute the report automatically.
### Workflow Overview
1. **Trigger node:** Scheduled trigger (e.g., daily or weekly).
2. **Data retrieval node:** Query Google Analytics Reporting API to fetch feature usage events.
3. **Data processing node:** Transform and aggregate the raw event data.
4. **Google Sheets node:** Append or update aggregated data in a Google Sheet.
5. **Reporting node:** Generate summary or charts if required.
6. **Notification node:** Post link or summary report to Slack or send via email.

### Step-By-Step Technical Tutorial
#### Prerequisites
– An n8n instance (cloud or self-hosted).
– Access to Google Analytics account with read permissions and credentials for API.
– Google Sheets set up with an appropriate spreadsheet for storing data.
– Slack workspace/email account for notifications.
#### Step 1: Set Up the Scheduled Trigger
– Add a **Cron** node in n8n.
– Configure the schedule (e.g., every day at 7 AM UTC or weekly on Monday at 8 AM).
– This will initiate the workflow at a regular cadence.
#### Step 2: Configure Google Analytics API Access
– In n8n, add an **HTTP Request** node to query the Google Analytics Reporting API.
– Use OAuth2 credentials configured in n8n or API credentials.
– Construct the API request to fetch feature usage events. Example query:
– **Endpoint:** `https://analyticsreporting.googleapis.com/v4/reports:batchGet`
– **Request body:** Specify the date range (e.g., last 7 days), metrics (event count), and dimensions (event label or event action for feature names).
– Example request body (JSON):
“`json
{
“reportRequests”: [
{
“viewId”: “YOUR_VIEW_ID”,
“dateRanges”: [{“startDate”: “7daysAgo”, “endDate”: “today”}],
“metrics”: [{“expression”: “ga:totalEvents”}],
“dimensions”: [{“name”: “ga:eventLabel”}]
}
]
}
“`
– Parse the response JSON to extract event labels and their counts.
#### Step 3: Process and Aggregate Data
– Add a **Function** or **Code** node to transform the API data into a tabular format that Google Sheets can consume.
– Example transformation:
– Extract each event label (feature name).
– Extract the total event count (usage count).
– Optionally calculate percentage shares or compare with previous periods.
– Output an array of objects like:
“`json
[
{“Feature”: “Login”, “UsageCount”: 1234},
{“Feature”: “New Dashboard”, “UsageCount”: 876},
{“Feature”: “Search”, “UsageCount”: 450}
]
“`
#### Step 4: Append or Update Data in Google Sheets
– Set up a **Google Sheets** node in n8n.
– Authenticate with your Google account.
– Select the spreadsheet and worksheet where you want to store the reports.
– Configure the node to append rows or update existing rows based on a unique key like feature name.
– Make sure the sheet columns correspond to the object keys: Feature, UsageCount, Date.
– You can add a column with the report date for reference.
#### Step 5 (Optional): Generate Summary or Charts
– You can add another Function node to calculate summary statistics from the data.
– Alternatively, configure Google Sheets to generate charts based on the data.
– If you want n8n to generate a PDF or image of the report, consider integrating with Google Docs API or third-party reporting tools.
#### Step 6: Send Notifications
– Add a **Slack** node to post a message to a specific channel with a summary of feature usage or a link to the Google Sheet.
– Alternatively, use the **Email Send** node to dispatch a formatted report to stakeholders.
– Example Slack message:
“`
New feature usage report for the last week is available: [Google Sheets Link]
Top used feature: Login with 1,234 events.
“`
### Common Errors and Robustness Tips
– **API Rate Limits:** Google Analytics API has daily quotas. Add error handling and retries in n8n.
– **Data Freshness:** Ensure your query date ranges do not overlap or skip days.
– **Authentication Expiry:** Set up OAuth2 credentials properly and monitor token expiry.
– **Data Schema Changes:** If event names or dimensions change, update your request and parsing logic.
– **Partial Failures:** Use n8n’s error workflows to capture failures and notify admins.
### Scaling and Adaptation
– To scale, add more data sources such as Segment, Mixpanel, or your custom event databases.
– Use n8n’s workflow parameters or environment variables to change report frequency or feature sets.
– Integrate BI tools like Looker or Tableau by exporting processed data.
– Add data cleansing steps or anomaly detection to highlight unusual usage patterns.
### Summary and Bonus Tip
Automating feature usage report generation with n8n streamlines product analytics workflows and delivers timely insights without manual overhead. By scheduling data retrieval, processing, and notification in a single pipeline, product teams can focus on decision-making rather than data wrangling.
**Bonus Tip:** To enhance your workflow, implement incremental data fetching by storing the last run timestamp and querying only new events. This reduces API usage and processing time, especially useful for large datasets.
