Read on to learn how to transform your Digital Services Act trust & safety evidence logs from a manual burden into an automated, scalable workflow.

The Problem: Digital Services Act Compliance Challenges in Lisbon

The client is a SaaS product company based in Lisbon, Portugal, operating in the digital services vertical. Their operations team was responsible for managing trust and safety tasks essential to comply with the European Union’s Digital Services Act (DSA). This regulation requires platforms to maintain meticulous evidence logs documenting safety operations, user notices, takedown actions, and risk assessments to ensure platform accountability and transparency.

Before automation, the team relied heavily on manual processes: spreadsheets, email threads, and siloed documentation. This led to:

• High manual workload: Operations staff spent up to 15 hours per week compiling and validating logs.
• Error-prone record keeping: Human error caused frequent omissions and inaccurate timestamps.
• Lack of audit-readiness: At audit time, incomplete documentation caused delays and raised compliance risks.
• Poor visibility: Reporting was fragmented, reducing situational awareness for management and compliance officers.

These issues caused delays responding to user notice-and-action requests, stretched limited operations resources, and increased regulatory risk — potentially jeopardizing platform licenses and user trust.

Our Approach: Discovery and Automation Strategy by RestFlow

RestFlow partnered with the client to map and analyze their trust and safety operations. Our discovery phase involved:

• Interviewing the operations team in Lisbon to document current workflows and pain points.
• Identifying key systems in use: Gmail for communications, Google Sheets for logging, Slack for alerts, and a custom CRM for case management.
• Understanding regulatory requirements: DSA themes like platform accountability, transparency, notice-and-action, and risk assessments.

We proposed an automation architecture based on n8n’s open-source workflow automation platform, hosted and managed by RestFlow. We recommended fully automating evidence log creation, updates, and audit reporting to ensure compliance and reduce manual effort. Our proposal included:

• Connecting Gmail and Slack for automated notifications and escalation.
• Using Google Sheets as a centralized data store for logs, due to existing user familiarity and real-time collaboration features.
• Integrating with the client’s CRM to synchronize case statuses and updates.
• Designing a workflow with embedded controls, automated approvals, error handling, and real-time dashboards.

This approach ensures efficiency and regulatory compliance, with flexible extensibility and scalable hosting by RestFlow’s Automation-as-a-Service model.

The Solution: Architecture & Workflow

Global Architecture Overview

The automated workflow is orchestrated via n8n, triggered by multiple real-world events:

• Trigger: Incoming user notice emails received in Gmail with specific DSA-related labels.
• Workflow tool: n8n, managed and hosted by RestFlow.
• External Services Integrated: Gmail (Email parsing and notifications), Google Sheets (evidence log storage), Slack (real-time alerts), Custom CRM API (case sync).
• Outputs: Audit-ready evidence logs stored centrally, real-time Slack updates to operations, automated summary reports emailed weekly to compliance officers.

End-to-End Workflow Walkthrough

Step by step, the workflow executes as follows:

1. Trigger: New email labeled with “DSA Notice” arrives in Gmail inbox.
2. Email Parsing: Extract notice details—case ID, timestamps, user ID, complaint type.
3. Validation: Check completeness of extracted data; if incomplete, send Slack alert to operations for manual review.
4. Data Logging: Add verified entry to Google Sheets trust & safety log with timestamp and auto-generated unique ID.
5. CRM Sync: Update the custom CRM case status and attach relevant evidence links.
6. Approval Check: If certain risk thresholds or content types are detected, trigger Slack approval request to compliance lead.
7. Final Notification: On approval, send confirmation email to the original user and log the action.
8. Weekly Reporting: Aggregate weekly logs and email summary report to compliance officers for audit readiness.

This end-to-end flow transforms previously manual checklist tasks into a streamlined, automated compliance operation.

Step-by-Step Node Breakdown of the Workflow 🚀

1. Gmail Trigger Node

This node triggers the workflow each time a new email arrives with the “DSA Notice” label in Gmail.
Key configuration:
– Watch for new emails with label “DSA Notice”.
– Fetch email content and metadata.
Output:
– Email subject, sender, timestamp, body.

2. Email Parser Node

Parses the email content to extract trust & safety relevant fields:
– Case ID.
– User ID.
– Complaint type.
– Date of the incident.
Uses regex filters and n8n expressions to detect and extract fields.
If parsing fails, triggers error handling.

3. Data Validator Node ⚠️

Checks if all required fields are present and valid.
– If valid, proceed.
– If missing data, send Slack alert to operations channel for manual intervention.
This condition uses ‘if’ logic in n8n with expressions checking JSON paths.

4. Google Sheets Append Node

Adds the parsed and validated data as a new row in the dedicated “Trust & Safety Evidence Logs” spreadsheet.
Key fields mapped:
– Timestamp.
– Case ID.
– Complaint Type.
– User ID.
Includes formulas to generate unique record IDs.

5. CRM Update Node

Calls custom CRM API to update the respective case record:
– Finds case by Case ID.
– Updates status and attaches evidence link from Google Sheets.
Uses OAuth2 for secure authentication.
Implements retries for API call failures.

6. Slack Approval Request Node 🛠️

If complaint type requires manager approval based on risk assessment:
– Posts a Slack message to compliance lead channel with action buttons.
– Waits for approval or rejection response.
– Uses Slack interactions API to listen for button clicks.
– Depending on response, continues or aborts workflow.

7. Email Notification Node

Sends confirmation email back to the user informing about takedown or action taken.
Uses Gmail SMTP integration.
Includes dynamic content based on workflow data.

8. Weekly Report Aggregator Node

Scheduled to run every Monday morning:
– Queries Google Sheets for past week entries.
– Generates summarized report (CSV and PDF).
– Emails report to compliance officers’ distribution list.

Error Handling, Robustness & Security

Error Handling and Retries

Every external API call (Google Sheets, CRM, Slack) has retry logic with exponential backoff in case of transient failures. Workflow branches on failures to alert operations immediately by Slack, ensuring no unnoticed errors. Any critical failure triggers Slack alert with detailed logs.

Logging and Observability

n8n maintains execution history for each workflow run. RestFlow’s monitoring dashboard consolidates logs to detect anomalies. Alerts are sent on error rate thresholds via Slack and email. Additionally, a fallback Google Sheet logs error cases for offline review.

Idempotency and Deduplication

Unique record IDs prevent duplicate processing. The workflow checks if an email with a given case ID has been processed before appending to Google Sheets.

Security and Data Protection

• All API tokens and credentials are securely stored using n8n’s encrypted credential store.
• Least privilege principles applied to all integrations.
• User PII data masked or excluded when not strictly needed.
• Access controls enforce only authorized users can edit workflows or view sensitive data.

Performance, Scaling & Extensibility

The workflow is designed to scale as case volume grows:

• Webhook triggers from Gmail: Efficient event-driven design avoids polling overhead.
• Batch processing: Weekly reports are generated by batching entries to avoid overwhelming API limits.
• Parallelization: n8n handles multiple concurrent workflow executions safely.
• Modular workflows: The architecture modularizes parsing, validation, and notification steps for easy maintenance.
• Extensibility: New complaint types or teams can be added by updating conditional logic and Slack channels.

Combined with RestFlow’s managed hosting, the system remains resilient and performant.
