## Introduction
In fast-paced product environments, Product Managers (PMs) rely heavily on timely and accurate Key Performance Indicators (KPIs) to make informed decisions. Manually gathering data from multiple sources and then compiling reports can be time-consuming and error-prone. Automating KPI notifications streamlines this process, ensuring PMs receive real-time insights without manual effort. This article details a step-by-step tutorial on building an automation workflow using n8n that pulls product KPIs from various data sources, processes the data, and sends concise, actionable notifications to PMs via Slack and email.
This automation primarily benefits the Data & Analytics team, PMs, and operations specialists focused on data-driven product management.

## Tools and Services Integrated
– **n8n:** Open-source workflow automation tool to orchestrate the entire process.
– **Google Sheets:** Stores or retrieves raw KPI data.
– **PostgreSQL/MySQL (Optional):** Query database for KPIs if data is stored in a relational database.
– **Slack:** Sends real-time KPI updates.
– **Email (SMTP or services like SendGrid):** Backup or alternative notification channel.
– **HTTP Request Node:** To query APIs or other data sources (e.g., product analytics APIs).

## Automation Workflow Overview
**Trigger:** Scheduled interval (e.g., daily at 9 AM) to automate fetching and sending KPIs.
**Steps:**
1. **Fetch KPI Data:** Retrieve KPIs from Google Sheets, databases, or API endpoints.
2. **Process Data:** Calculate or aggregate KPIs if needed.
3. **Format Message:** Create a structured summary message highlighting key metrics.
4. **Send Notifications:** Post message to Slack channels and send email alerts.

## Step-by-Step Technical Tutorial
### Step 1: Setting Up the Trigger Node
– In n8n, drag the **Cron** node to your canvas.
– Configure it to run at your preferred interval (e.g., daily at 9 AM).
– This node will initiate the automation.
### Step 2: Fetch KPI Data
Depending on where your KPIs reside, choose one or more options:
#### Option A: Google Sheets
– Add a **Google Sheets** node.
– Authenticate with your Google account.
– Configure it to read the range of cells containing the KPI data.
– Select ‘Read Rows’ operation.
#### Option B: Database Query
– Add a **PostgreSQL** or **MySQL** node.
– Connect to your relational database by providing host, user, password, database name.
– Write an SQL query to fetch aggregated KPIs (e.g., daily active users, conversion rate).
#### Option C: API Endpoint
– Add an **HTTP Request** node.
– Set method to GET.
– Input the product analytics API URL.
– Include authentication headers as required.
### Step 3: Process and Transform Data
– Use the **Function** or **Set** node to manipulate raw data.
– Example: Calculate percentage changes, format numbers, filter important KPIs.
– Example JavaScript snippet in a Function node:
“`javascript
const data = items[0].json;
return [{ json: {
activeUsers: data.active_users,
conversionRate: (data.conversions / data.visits * 100).toFixed(2) + ‘%’,
revenue: ‘$’ + data.revenue.toFixed(2)
}}];
“`
### Step 4: Format Message for Slack and Email
– Add a **Function** node that builds a Slack message block or plain text email body.
– For Slack, use the Block Kit format for readability.
Example Slack message JSON builder:
“`javascript
return [{ json: {
channel: ‘product-management’,
text: ‘Daily Product KPIs’,
blocks: [
{ type: ‘section’, text: { type: ‘mrkdwn’, text: ‘*Daily Product KPIs Summary*’ } },
{ type: ‘divider’ },
{ type: ‘section’, text: { type: ‘mrkdwn’, text: `*Active Users:* ${items[0].json.activeUsers}` } },
{ type: ‘section’, text: { type: ‘mrkdwn’, text: `*Conversion Rate:* ${items[0].json.conversionRate}` } },
{ type: ‘section’, text: { type: ‘mrkdwn’, text: `*Revenue:* ${items[0].json.revenue}` } }
]
}}];
“`
### Step 5: Send Notifications
#### Slack Notification
– Add the **Slack** node.
– Authenticate using OAuth or webhook.
– Choose ‘Post Message’ operation.
– Use channel and message from the previous node.
#### Email Notification
– Add the **Email** node.
– Configure SMTP or integrate with providers like SendGrid.
– Compose the email using the same message content.

## Common Errors and Tips for Robustness
– **Authentication Failures:** Regularly refresh OAuth tokens or use service accounts.
– **API Rate Limits:** Implement error handling and retry mechanisms in HTTP Request nodes.
– **Data Format Changes:** Validate data input and add conditional checks in Function nodes to catch unexpected changes.
– **Notification Failures:** Use n8n’s error workflow option to catch and alert failures.
– **Time Zone Issues:** Ensure that the Cron node’s scheduling aligns with your PMs’ time zones.

## Adapting and Scaling the Workflow
– To scale for multiple products, add a loop using the **SplitInBatches** node to iterate over product list.
– Integrate additional KPIs by extending database queries or API requests.
– Send personalized notifications using dynamic Slack channels or named email recipients.
– Use n8n’s Credentials system to securely manage multiple data source connections.
– Enhance messages with links to dashboards or drill-down reports using markdown formatting.

## Summary and Bonus Tip
Automating the notification of product KPIs using n8n drastically reduces manual reporting effort, improves accuracy, and accelerates decision-making for PMs. This workflow leverages n8n’s flexible nodes to fetch, process, and deliver insightful KPI summaries through popular communication channels.
**Bonus Tip:** To enable interactive KPI tracking, integrate buttons or dropdown menus in Slack messages that trigger follow-up workflows (e.g., fetch weekly trends, enable alerts for specific metrics) using Slack’s interactive messaging features and n8n webhooks. This transforms static reports into dynamic, actionable interfaces.
By following this guide, Data & Analytics teams can empower their product teams with reliable, automated KPI visibility integral to agile product management.
