The Problem: Navigating DORA Compliance Challenges in Munich

The client is a medium-sized compliance services company headquartered in Munich, Germany. Operating in the compliance vertical, they specialize in advisory and audit services for financial and ICT sectors. The key department impacted was their operational risk and IT compliance team responsible for maintaining operational resilience under the European Union’s DORA regulation.

DORA mandates stringent oversight on operational resilience, ICT risk, third-party dependencies, testing regimes, and incident reporting. Change management and patching processes are core to demonstrating compliance, requiring precise evidence for audit trails.

Prior to automation, the team managed patch approvals, status tracking, and evidence collection manually using disparate spreadsheets, emails, and shared drives. This approach led to frequent delays—approximately 20 hours per month spent collating evidence—and a 15% error rate in audit documentation, leading to failed or delayed audits. Operational teams experienced stress due to the high risk of non-compliance penalties and reputational damage.[Source: internal audit data]

Further, manual handling of approvals and evidence storage posed challenges in visibility and real-time monitoring, putting operational resilience and ICT risk controls at risk. Third-party software patching required cumbersome coordination without centralized tracking.

Ultimately, the company sought an automated, scalable solution to reduce compliance risks and improve audit readiness under DORA.

Our Approach: Mapping and Automating Compliance Workflows

RestFlow began by conducting comprehensive process discovery workshops with the client’s compliance and IT teams. We mapped the end-to-end change management lifecycle, identifying key steps:

• Request submission for patching/changes.
• Approval workflows involving managers and security teams.
• Patch deployment updates from IT teams.
• Automated evidence collection and report generation.

We identified critical systems involved, such as Gmail for communications, Google Sheets as interim data stores, Slack for real-time notifications, and the client’s internal document repository for storing audit evidence.

To achieve seamless orchestration, we proposed an automation architecture using RestFlow’s Automation-as-a-Service platform powered by n8n. n8n’s low-code workflow capabilities combined with RestFlow’s service model ensures maintainability and compliance-first design.

Our high-level architecture connected triggers like new change requests from a Google Form submission webhook, approval steps through Slack message interactions, status updates linked to Google Sheet rows, and final evidence export to an internal SharePoint folder.

This approach aimed to reduce manual reconciliation, increase transparency, and ensure audit-ready evidence with minimal human intervention.

The Solution: Architecture & Workflow

Automation Architecture Overview

The automation architecture centers on orchestrating change management and patching evidence workflows under DORA using n8n as the orchestrator hosted by RestFlow.

• Triggers: Webhooks triggered by Google Form submissions and scheduled checks to detect patch status.
• Orchestration tool: n8n workflows designed and maintained by RestFlow.
• External services: Gmail for notifications and communications; Google Sheets as intermediate data stores and status dashboards; Slack for real-time approvals and alerts; SharePoint for storing final audit evidence documents.
• Outputs: Audit-ready reports exported as PDFs, dashboards update for operational visibility, Slack notifications for approval requests and status updates.

End-to-End Workflow Walkthrough

1. Change Request Submission: The process initiates when an IT team member submits a patch/change request through a Google Form. This triggers an n8n webhook.
2. Data Capture and Validation: n8n immediately parses the form data, validating required fields (change ID, affected system, patch version, planned deployment date).
3. Approval Workflow: An automated Slack message is sent to designated approvers containing change details and buttons to Approve or Reject. The workflow pauses for the response.
4. Patch Deployment Tracking: Once approved, the workflow monitors patch deployment status via scheduled checks or manual input update in Google Sheets.
5. Evidence Collection: Upon deployment confirmation, n8n collects logs and screenshots uploaded by IT from their document repository and generates audit evidence files.
6. Audit Report Generation: Compiled evidence is formatted into a PDF report and automatically uploaded to the SharePoint compliance folder for audit access.
7. Notifications: Throughout the process, email notifications through Gmail and Slack alerts keep stakeholders informed.

This automated orchestration replaces the previously manual, error-prone process with a transparent, traceable system that embeds key DORA compliance controls.

Step-by-Step Node Breakdown 

Webhook Trigger: Capturing Change Requests

The starting point is an n8n Webhook node configured with a unique endpoint URL to listen for Google Form submissions. This node authenticates incoming requests via a secret token parameter embedded in the form’s Apps Script.

The node extracts JSON-formatted form data with fields like RequestorEmail, SystemAffected, and PatchVersion. This ensures seamless integration with existing client form infrastructure.

Data Validation and Enrichment

Following the webhook, a Function node validates mandatory fields, checks date formats, and enriches data by querying a Google Sheets reference table that contains system owners and risk scores.

Conditional logic in the node flags errors for missing data, triggering Slack alert notifications to the compliance team to prevent workflow continuation until corrected.

Slack Approval Request 

An n8n Slack node composes an interactive message to approvers featuring the change details and buttons: Approve, Reject. This node uses Slack’s Block Kit layout.

Pending responses are tracked by a Wait node with a 48-hour timeout, after which an escalation message is sent to senior compliance via Slack.

Expressions map the webhook payload data into the message text, and button clicks trigger callback workflows to capture decisions.

Patch Deployment Monitoring

Upon approval, a custom Scheduler triggers periodic checks every 8 hours. This node queries the Google Sheet ‘Patch Status’ tab filtering by change ID and verifying deployment fields.

When the deployment is marked complete, the workflow proceeds to evidence collection.

Evidence Compilation & Report Generation

The n8n HTTP Request node downloads deployment logs and screenshots from the client’s document management API, using stored credentials securely managed as environment variables.

A Merge node aggregates all evidence. Then a PDF generation node composes a standardized compliance report embedding metadata and timestamps.

The final PDF is uploaded to SharePoint using Microsoft Graph API, maintaining an organized folder hierarchy structured by month and system.

Notifications and Dashboards

Throughout the workflow, Gmail nodes send summary emails to the compliance and IT teams. Google Sheets API nodes update a status dashboard in real time.

Slack messages notify operational leads of approvals, status changes, and audit readiness.

Error Handling, Robustness & Security

Error Handling and Retries

The workflow employs advanced error handling techniques. Each critical node is paired with error triggers that send formatted Slack error alerts and log events in a Google Sheets error tracking log.

The system implements exponential backoff retries (up to 3 attempts) for transient errors like API rate limiting or temporary connectivity issues.

Logging, Observability & Alerting

RestFlow integrates detailed run logs within n8n’s monitoring dashboard. Slack channels serve as real-time alert destinations for failures or SLA breaches.

Custom tags and metadata attached to each run assist in post-mortem analysis.

Idempotency & Deduplication

Webhook triggers include request IDs. Before processing, workflows query Google Sheets for existing request IDs to avoid duplicate runs.

This idempotency ensures audit data consistency.

Security & Data Protection

All API keys and tokens are stored securely in n8n credential vaults with least-privilege permissions.

Access control is enforced by RestFlow’s single sign-on (SSO) and role-based access.

PII fields like requestor emails are encrypted where required, and GDPR compliance is maintained.

Performance, Scaling & Extensibility

The workflow’s architecture supports scaling through:

• Webhook triggers allow event-driven scaling, eliminating inefficient polling.
• Queues manage batches of change requests, enabling concurrency.
• Modular workflows allow rapid adaptation to new client environments or regulatory updates.

RestFlow’s managed hosting environment supports high availability and safe version deployments using staging and production workflow versions to prevent business disruption.
