Case Context & The Problem

The client is a fast-growing customer support department based in Berlin, Germany, serving a well-known digital platform provider. Operating in the highly regulated tech sector, the team is on the front lines of content moderation and customer communication.

With the Digital Services Act (DSA) newly enacted by the European Union, the client’s team was required to handle a surge of notices regarding illegal or harmful content on their platform. The DSA mandates strict notice-and-action procedures, transparency in reporting, platform accountability, and risk assessments — all under tight timelines.

Before automation, the process was primarily manual:

• Email notices from users and authorities were collected and tracked in spreadsheets.
• Support agents manually verified, prioritized, and escalated cases.
• Multiple systems were involved without integration — Gmail, internal CRMs, Slack, and Google Sheets.
• Reporting to the legal and compliance teams was tedious and error-prone.

The manual approach led to significant challenges:

• Time wasted: Support staff spent 20+ hours weekly managing logs and chasing updates.
• Risk of missing deadlines: The DSA requires action within days; manual tracking caused delays.
• Errors and inconsistencies: Duplicate entries and miscommunication were frequent.
• Lack of real-time visibility: Management could not easily track progress or compliance status.

The business impact was tangible — compliance risk increased, SLA breaches became likely, and employee stress levels rose. The client needed a robust, scalable automation solution to regain control and ensure compliance.

Our Approach: Discovery and Proposal

RestFlow initiated the project with a comprehensive discovery phase involving detailed process mapping and requirement gathering. We collaborated closely with the client’s customer support leads and compliance officers to understand:

• How notices arrive, are classified, acted upon, and reported
• Key systems involved — Gmail for inbound notices, Google Sheets for tracking, Slack for internal alerts, internal CRM for customer data
• Pain points and bottlenecks within current workflows
• Compliance requirements from the Digital Services Act, focusing on notice-and-action workflows

After synthesizing these insights, we proposed an automation architecture leveraging RestFlow’s managed Automation-as-a-Service platform with n8n as the orchestration tool. This choice was due to n8n’s flexibility in designing complex workflows, extensive integration capabilities, and open-source nature aligned with the client’s security standards.

Our high-level design aimed to:

• Automatically capture and parse incoming DSA notices via Gmail webhook triggers
• Validate, classify, and route notices to appropriate agents with approval controls
• Track all actions within a centralized Google Sheet database with audit logs
• Notify teams via Slack for urgent or escalated cases
• Generate periodic compliance reports transparently accessible by management

This automation would ensure the client’s platform accountability and transparency mandates under the DSA, all while reducing manual labor and error risk.

The Solution: Architecture & Workflow

Global Architecture Overview

The architecture consisted of four key components:

• Triggers: Gmail webhook monitoring new incoming emails with specific keywords indicating a DSA notice
• Orchestration: n8n platform running hosted by RestFlow to process, validate, and route data
• External Services: Integrations with Gmail (inbound notices), Google Sheets (tracking and logging), Slack (notifications), and internal CRM APIs for data enrichment
• Outputs: Real-time notifications, audit logs, and automated reports for compliance management

End-to-End Workflow Walkthrough

1. Trigger: Incoming emails to a dedicated Gmail inbox are captured using a Gmail webhook.
2. Parsing & Validation: n8n parses email content using built-in nodes and extracts key fields — notice type, sender, date, and content.
3. Classification: Logic nodes decide the risk level and urgency based on keywords and metadata.
4. Data Enrichment: CRM API called to enrich sender info (e.g., user ID, previous interactions).
5. Storage: Validated and enriched data added to Google Sheets with timestamp and status columns.
6. Approval Step: Notification sent via Slack to assigned support agents for review and decision.
7. Action Logging: Agents update the status, triggering workflow nodes to reflect progress and log actions.
8. Escalation: Notices failing to meet SLAs automatically escalate via Slack alerts to managers.
9. Reporting: Weekly summary reports generated and circulated automatically to compliance stakeholders.

This streamlined workflow touches on all crucial phases of DSA-compliant notice-and-action workflow, dramatically improving speed and accuracy.

Step-by-Step Node Breakdown 🔧

1. Gmail Webhook Trigger 📩

This node listened to the Gmail dedicated mailbox, using watch label filters focused on subject lines mentioning “DSA Notice” or related terms.
Outputs were JSON payloads containing email metadata and raw message content, which served as the primary input for parsing.

2. Email Parsing and Data Extraction 🔍

Using n8n’s “HTML Extract” and “Text Parser” nodes, key elements were extracted:

• Notice ID and sender’s email
• Date of receipt
• Reported content details

Expressions such as {{$json["subject"]}} and regex filters helped validate relevant notices.

3. Classification Logic ⚖️

Conditional nodes evaluated risk:

• If keywords included “illegal”, “harmful”, or law enforcement mention ⇒ set high priority
• Else moderate or low priority

This branch dictated notification paths and SLA deadlines.

4. CRM Data Enrichment 🔗

A HTTP Request node communicated with the internal CRM API:
GET /users?email={{$json["sender"]}}
to retrieve user history, previous complaints, and risk indicators.

Mapped outputs included userId and account status, essential for compliance reporting.

5. Google Sheets Integration 🗂️

Using the Google Sheets node, the workflow created or updated rows representing notices:

• Columns included: Notice ID, Sender, Priority, Status, Assigned Agent, Timestamps
• Using filters to check for duplicates ensured idempotency

6. Slack Notifications and Approvals 🔔

Slack nodes notified the assigned support agents:

• Messages contained clickable approval buttons (approve, escalate)
• User responses triggered webhook callbacks to update the Google Sheet and proceed accordingly

7. Escalation & SLA Management ⏰

Scheduler nodes ran periodic checks on pending notices:

• Overdue entries triggered escalation Slack alerts to managers
• Actions written back to Sheets to update status

8. Compliance Reporting and Dashboard 📊

A workflow scheduled weekly generated CSV exports of notices and actions:
These reports were emailed to compliance teams and uploaded to SharePoint for transparency.

Error Handling, Robustness & Security

Error Handling and Retries

Failed API calls or network issues in CRM or Slack nodes employed exponential backoff retry policies integrated into n8n.

Errors were logged into a dedicated Google Sheet error queue monitored by the RestFlow team for proactive remediation.

Logging and Observability

All workflow executions were logged centrally, with detailed status codes and timestamps.
Slack alerts constanly notified ops teams of errors or performance anomalies.

Alerts and Deduplication

Idempotency keys based on notice IDs ensured that duplicate emails or webhook repeats did not create redundant entries.

Slack alerts for failures helped maintain SLA adherence.

Security and Data Protection

API tokens and sensitive credentials were stored securely in n8n environment variables with least privilege scopes.
All PII was handled per GDPR guidelines, with encrypted storage for sensitive fields.
Access controlled via role-based permissions to audit flows and monitor changes.

Performance, Scaling & Extensibility

The workflow was designed to scale:

• Webhooks over Polling: Gmail webhook triggers reduced polling latency and compute overhead
• Parallelization: High-priority notices forked into parallel Slack notifications and CRM lookups
• Queueing: Google Sheets error queue prevented data loss during outages
• Modular workflows: Distinct sub-workflows handled parsing, enrichment, approval, making adaptation easy

Adding new teams or expanding to new geographies primarily required updating Slack channels and CRM API endpoints without disrupting core logic.
