## Introduction
SaaS tools are integral to modern startups and enterprises, enabling teams to collaborate, streamline processes, and increase productivity. However, with the proliferation of SaaS subscriptions across departments, operations teams often struggle to maintain oversight on tool usage and access. Inefficient SaaS management can lead to ballooning costs, security risks, and compliance issues.
This article presents a detailed, step-by-step guide to building an automated workflow using n8n to track SaaS tool usage and access across your organization. By the end, operations teams, automation engineers, and startup CTOs will have a practical, scalable solution that integrates popular apps and databases to centralize SaaS usage analytics and notifications.

## What Problem Does This Automation Solve?
– **Visibility:** Gain real-time insight into who is using which SaaS tools and how frequently.
– **Access Management:** Detect unauthorized or inactive users to mitigate security risks.
– **Cost Control:** Identify underutilized licenses that can be downgraded or canceled.
– **Operational Efficiency:** Eliminate manual spreadsheets or siloed data sources.
**Primary Beneficiaries:**
– Operations teams handling SaaS vendor management
– Security teams monitoring access controls
– Finance teams managing software budgets

## Tools and Services Integrated
– **n8n:** Open-source automation platform used to orchestrate the workflow.
– **G Suite (Google Workspace):** To pull user email lists and organizational units.
– **SaaS Provider APIs:** Example providers like Slack, Zoom, GitHub, or HubSpot.
– **Google Sheets:** Centralized database to log SaaS usage data.
– **Slack:** For alerting and notifications.
– **Email:** For sending periodic summary reports.
*Note:* Specific SaaS APIs vary by provider, but most support querying active users, license assignments, and some usage metrics.

## How the Workflow Works: From Trigger to Output
The workflow is divided into three major phases:
1. **Trigger:** Scheduled daily (or weekly) execution via n8n’s Cron node.
2. **Data Aggregation:** For each SaaS tool, API calls fetch users, licenses, and usage stats;
data is normalized and appended to a centralized Google Sheet.
3. **Analysis & Notification:** The workflow processes the data to identify anomalies such as inactive users or over-provisioned licenses, sending alerts via Slack and summary emails.

## Step-by-Step Breakdown of the Automation Workflow
### Step 1: Schedule the Workflow
– Use the **Cron** node in n8n to trigger the workflow at a set time (e.g., every day at 2 AM).
### Step 2: Fetch Organizational User List
– Use the **Google Workspace API** node or **HTTP Request** node to pull the list of active employees.
– This list serves as a baseline to cross-reference SaaS user data.
### Step 3: Fetch SaaS User Data Per Tool
For each SaaS provider, create a subflow:
– **Slack:** Use Slack’s API `users.list` to get all workspace members.
– **Zoom:** Use Zoom’s API to list users and their last login timestamps.
– **GitHub:** Use GitHub’s REST API to list organization members and their last commit or activity.
– **HubSpot:** Fetch active users and license assignments via HubSpot API.
*Tip:* Add API credentials securely through n8n’s credential management.
### Step 4: Normalize and Aggregate Data
– Use n8n’s **Function** or **Set** nodes to standardize user data fields: name, email, last active date, license status.
– Consolidate results from each SaaS tool into a uniform schema.
### Step 5: Update Google Sheets
– Use the **Google Sheets** node to append or update rows for each SaaS user entry.
– Organize sheets by tool or as a master consolidated sheet.
### Step 6: Analyze the Data
– Use a **Function** node coded in JavaScript to:
– Identify users inactive beyond a defined threshold (e.g., 30 days).
– Detect users in SaaS tools not in the official org list (potential unauthorized access).
– Flag licenses assigned but seldom used.
### Step 7: Send Alerts
– For any anomalies, use the **Slack** node to send alert messages to operations/security channels.
– Use the **Email** node to send a weekly summary report with key metrics.
### Step 8: Logging and Error Handling
– Add **Error Trigger** nodes to capture runtime errors.
– Log errors to a dedicated Slack channel or email for quick remediation.

## Common Errors and Tips for Robustness
– **API Rate Limits:** Most SaaS APIs have throttling. Use n8n’s built-in rate-limiting or add delays between API calls.
– **Credential Expiration:** Refresh API tokens regularly and handle authentication errors gracefully.
– **Data Inconsistencies:** SaaS APIs may return incomplete data; implement retries and validation checks.
– **Schema Changes:** Regularly update the workflow to adjust for API changes from SaaS providers.
– **Scaling:** For organizations with many SaaS tools or thousands of users, split workflows and use batch processing.
—
## How to Adapt or Scale the Workflow
– **Add More SaaS Tools:** Build modular subflows for each additional service.
– **Real-Time Monitoring:** Instead of scheduled runs, implement webhooks or event triggers if supported.
– **Integrate with CMDB or ITSM:** Push cleaned data into Configuration Management Databases or ServiceNow for audit purposes.
– **Advanced Analytics:** Export usage data to BI tools like Looker or Power BI for deeper insights.
– **User Deprovisioning Automation:** Extend workflow to disable access or revoke licenses automatically for inactive users.

## Summary & Bonus Tip
Tracking SaaS tool usage and access through n8n automation empowers operations teams to maintain control over software assets, optimize costs, and improve security posture. By systematically pulling usage data via APIs, consolidating it into actionable formats, and alerting on abnormalities, your organization gains unprecedented visibility and responsiveness.
**Bonus Tip:** Use n8n’s workflow versioning and Git integration to manage iterative improvements and collaborate across teams. Additionally, document API credentials and workflow nodes meticulously to ease maintenance and onboarding.
