## Introduction
Sales teams and data analytics departments often face the challenge of tracking campaign performance and conversion rates in real time. Manual reporting is time-consuming, error-prone, and lacks agility. Automating sales conversion reporting by campaign can save countless hours, reduce errors, and enable quick, data-driven decision-making.
This article provides a step-by-step technical guide to building an automated workflow using n8n — an open-source no-code/low-code automation tool — to aggregate sales data, link it to marketing campaigns, calculate conversion metrics, and deliver scheduled reports.
### Who benefits?
– Data & Analytics teams who prepare sales and marketing reports
– Marketing teams tracking campaign ROI
– Sales leadership monitoring pipeline effectiveness
### What problem does this automation solve?
It eliminates manual data gathering from multiple platforms, cumbersome report building, and frequent ad hoc queries by automating the entire flow — from data ingestion to delivering digestible insights.

## Tools and Services Integrated
For this tutorial, we will integrate:
– **n8n**: Workflow automation platform
– **Google Sheets**: Stores raw sales and campaign data
– **HubSpot CRM**: Source of sales opportunities and campaign attribution
– **Slack**: Distribution channel for automated sales conversion reports
– **MySQL Database** (optional): For storing aggregated and historical data
This example demonstrates a common stack; n8n’s versatile nodes support many other platforms.

## Workflow Overview
The workflow will perform the following steps daily:
1. Trigger the workflow on a scheduled basis (e.g., every day at 7 AM).
2. Pull sales opportunities closed in the last day from HubSpot, including campaign attribution.
3. Load campaign data and sales KPIs from Google Sheets for reference.
4. Calculate sales conversion rates by campaign.
5. Store aggregated results in MySQL for historical tracking (optional).
6. Generate a formatted report.
7. Send the report to a dedicated Slack channel.

## Detailed Step-by-Step Tutorial
### Prerequisites
– Access to an n8n instance (on-prem or cloud-hosted).
– HubSpot API key with necessary read permissions.
– A Google account with a prepared Google Sheet containing campaign metadata.
– Slack webhook or bot token with permission to post messages.
– (Optional) MySQL database credentials.
### Step 1: Create a Scheduled Trigger
– Use the **Cron** node in n8n.
– Configure it to run daily at 7 AM (or your preferred time).
### Step 2: Retrieve Sales Opportunities from HubSpot
– Use the **HubSpot node** with the “Get All” operation.
– Set filters to only retrieve deals closed won during the previous day.
– Query campaign-related properties (e.g., ‘utm_campaign’, ‘source_campaign’) associated with each deal.
**Tip:** Use HubSpot’s pagination correctly to handle large volumes.
### Step 3: Load Campaign Metadata from Google Sheets
– Add a **Google Sheets node** to read campaign metadata (e.g., campaign names, budgets, start/end dates).
– This provides context for matching and validating campaign info against deals.
### Step 4: Data Processing and Aggregation
– Use the **Function node** in n8n to:
– Group deals by campaign.
– Count total opportunities and number of closed-won deals per campaign.
– Calculate conversion rates = (closed won / total opportunities) * 100.
Example snippet:
“`javascript
const deals = items.map(item => item.json);
let campaignMap = {};
deals.forEach(deal => {
const campaign = deal[‘utm_campaign’] || ‘Unknown’;
if (!campaignMap[campaign]) {
campaignMap[campaign] = { total: 0, won: 0 };
}
campaignMap[campaign].total += 1;
if (deal[‘dealstage’] === ‘closedwon’) {
campaignMap[campaign].won += 1;
}
});
return Object.entries(campaignMap).map(([campaign, data]) => ({ json: {
campaign,
totalOpportunities: data.total,
closedWon: data.won,
conversionRate: ((data.won / data.total) * 100).toFixed(2),
}}));
“`
### Step 5 (Optional): Store Aggregated Data in MySQL
– Use the **MySQL node** to insert or update daily campaign conversion metrics.
– This enables longitudinal analysis and reporting history.
### Step 6: Format Report Message
– Use a **Set node** or **Function node** to construct a Slack message with a clear tabular breakdown of:
– Campaign name
– Total opportunities
– Closed won deals
– Conversion percentage
Example Slack block section:
“`json
{
“type”: “section”,
“text”: {
“type”: “mrkdwn”,
“text”: “*Sales Conversion Report by Campaign*
| Campaign | Total Opportunities | Closed Won | Conversion Rate |
|———-|———————|————|—————–|
| {{campaign}} | {{totalOpportunities}} | {{closedWon}} | {{conversionRate}}% |”
}
}
“`
### Step 7: Post the Report to Slack
– Use the **Slack node** to send the formatted message to a designated channel.
– Choose “Post Message” operation and configure the channel ID and message content.

## Common Errors and Troubleshooting Tips
– **API Rate Limits:** Be mindful of HubSpot and Slack API quotas – implement error handling and retries in n8n.
– **Data Consistency:** Campaign names might vary across systems; consider normalizing campaign identifiers.
– **Authentication Issues:** Ensure OAuth tokens or API keys are valid and have correct permissions.
– **Pagination Handling:** For large datasets, always loop over paged API results.
– **Null or Missing Data:** Add checks to avoid runtime errors when fields like ‘utm_campaign’ are missing.
—
## Scaling and Adaptations
– **Multi-channel Reporting:** Extend workflow to aggregate data from additional CRMs or advertising platforms.
– **Advanced Analytics:** Integrate with BI tools by pushing data into data warehouses instead of Slack.
– **Custom Alerts:** Add conditional nodes to notify only when conversion rates drop below a certain threshold.
– **User Access:** Use role-based access controls or parameterize campaigns based on user groups.
