## Introduction
In today’s fast-paced sales environment, lead generation often happens across multiple platforms: website forms, social media ads, email campaigns, CRMs, and third-party lead providers. Sales teams struggle to keep track of all these inputs manually, leading to lost opportunities and inefficient workflows. Automating lead aggregation consolidates leads in one place, ensures real-time updates, improves lead response time, and enhances overall sales productivity.
This article provides a comprehensive, technical, step-by-step tutorial to build an automation workflow using n8n that aggregates leads from multiple sources like Google Forms, Facebook Lead Ads, and HubSpot into a centralized Google Sheet and sends real-time Slack notifications to sales reps. This solution is designed for sales ops specialists, automation engineers, and startup CTOs looking to streamline lead management.

## Workflow Overview
### What problem does this automation solve?
This workflow solves the problem of fragmented lead data across multiple platforms, manual data consolidation, and delayed lead notification. It benefits sales teams, sales operations, and marketing teams by providing a centralized, real-time view of incoming leads.
### How the workflow works (trigger to output)
1. **Trigger**: The workflow starts on schedule (e.g., every 15 minutes) or via webhooks triggered by lead submission events.
2. **Data Extraction**: Pull lead data from different sources:
– Fetch new form responses from Google Forms.
– Retrieve new leads from Facebook Lead Ads.
– Get recently created contacts or leads from HubSpot.
3. **Data Transformation**: Standardize and unify lead data fields.
4. **Aggregation**: Append or update the centralized Google Sheet with new leads.
5. **Notification**: Send Slack messages notifying the sales team of new leads.
6. **Error Handling**: Log errors if API calls fail or data is inconsistent.

## Step-by-Step Technical Tutorial
### Prerequisites
– n8n instance (Self-hosted or n8n.cloud account).
– Google Workspace account (Google Forms & Google Sheets).
– Facebook Developer account with Lead Ads setup.
– HubSpot CRM account.
– Slack workspace and webhook or app integration for notifications.
### Step 1: Setting up n8n
1. Log into your n8n instance.
2. Create a new workflow titled “Lead Aggregation Automation.”
### Step 2: Define Workflow Trigger
– Choose **Cron node** (if polling) or **Webhook** (if you want real-time).
For polling:
– Configure Cron to run every 15 minutes.
For webhooks (recommended for lower latency and efficiency):
– One webhook per lead source that triggers the rest of the workflow on lead submission.
### Step 3: Connect to Google Forms
Google Forms does not have a direct API in n8n, but form responses store in Google Sheets.
Approach:
– Use the **Google Sheets node** to read new rows from the Form Response spreadsheet.
Setup:
1. Add Google Sheets node.
2. Authenticate with your Google account.
3. Select ‘Read Rows’ operation.
4. Target your Form Responses sheet.
5. Filter rows based on last modified timestamp or a stored cell to avoid re-processing old leads.
Tip: Maintain a last-processed timestamp or row number in n8n workflow variables or on a separate sheet.
### Step 4: Connect to Facebook Lead Ads
1. Add Facebook Lead Ads node.
2. Authenticate using Facebook API credentials.
3. Use the ‘Get Leads’ operation.
4. Poll for leads created since the last run.
Implementation tips:
– Store the last lead ID or timestamp as workflow state to avoid fetching duplicates.
– Handle pagination if you expect many new leads.
### Step 5: Connect to HubSpot
1. Add HubSpot node.
2. Authenticate with HubSpot private app or OAuth.
3. Use the ‘Get Contacts’ or ‘Get Deals’ operation (depending on lead type).
4. Filter by creation date or use incremental updates.
### Step 6: Data Transformation and Standardization
1. After each source, add **Function nodes** to map fields uniformly.
2. For example, transform Facebook’s `full_name` to `name`, Google Forms’ `entry_1` to `email`, etc.
3. Include fields like name, email, phone, source, lead owner, creation date.
Example snippet inside Function node:
“`javascript
return items.map(item => {
const data = item.json;
return {
json: {
name: data.full_name || data.name || ”,
email: data.email_address || data.email || ”,
phone: data.phone_number || ”,
source: data.source || ‘Unknown’,
createdAt: data.created_time || new Date().toISOString(),
}
};
});
“`
### Step 7: Aggregate Leads Into Google Sheets
1. Add **Google Sheets node** configured to ‘Append’ mode.
2. Map fields to columns in your master leads sheet.
3. Use a unique field like email + source combo to prevent duplicates.
Optional:
– Use additional nodes to check if lead already exists:
– Read existing leads,
– Compare with new leads,
– Append only unique leads.
### Step 8: Send Slack Notifications
1. Add Slack node.
2. Authenticate via Slack OAuth or Webhook URL.
3. Configure message template with lead details:
> New Lead from {{ $json.source }}: {{ $json.name }} ({{ $json.email }})
4. Send notification to #sales or relevant channel.
### Step 9: Error Handling & Logging
– Add **Error Trigger node** to handle workflow failures.
– Log error details in a dedicated Google Sheet or external logging service.
– Use n8n’s Retry feature for intermittent API failures.
### Step 10: Maintain State for Incremental Fetching
– Use **Set node** and **Workflow static data** to store state variables like:
– Last row processed in Google Sheets.
– Last lead creation timestamp in Facebook and HubSpot.
This ensures only new leads are processed each run.

## Common Errors and Tips
– **API Quotas and Limits:** Facebook, HubSpot, and Google APIs have rate limits. Use throttling nodes or built-in delays in n8n to avoid hitting these.
– **Duplicate Leads:** Implement robust de-duplication strategy by checking unique identifiers.
– **Authentication Failures:** Keep tokens refreshed and monitor expiration.
– **Timezone Issues:** Normalize dates and times in UTC to avoid missing leads when filtering by creation timestamp.
– **Data Inconsistency:** Validate lead data format and required fields before appending.
– **Workflow Performance:** Avoid processing large history sets on each run; rely on incremental updates.

## How to Adapt or Scale This Workflow
– **Add More Lead Sources:** Extend with other platforms like LinkedIn Lead Gen Forms, Typeform, or custom webhooks.
– **CRM Integration:** Instead of or alongside Google Sheets, directly push leads into CRMs like Salesforce.
– **Lead Qualification:** Integrate lead scoring or enrichment services like Clearbit.
– **Multi-Channel Notifications:** Add email or SMS alerts to sales reps.
– **Error Monitoring:** Integrate monitoring tools like Sentry or PagerDuty.
– **Team Assignment:** Automatically assign leads to sales reps based on territory or load balancing rules.
