Personio Automation: Connect HR Processes with n8n and Make.com

Personio is a leading HR system for mid-sized businesses. Yet many companies aren't realizing its full potential: data is transferred manually between Personio and other systems, onboarding checklists are maintained in Excel, and IT tickets are created via email. In this guide, we'll show you how to take Personio to the next level with workflow automation. For a broader perspective, read our guide on HR onboarding automation.

Step-by-Step: Onboarding Workflow with n8n

Prerequisites

• n8n installation (Cloud or Self-Hosted)
• Personio API access
• Target system access (Google, Slack, etc.)

Creating the Workflow

Step 1: Set Up Personio Trigger

Since Personio doesn't offer native webhooks, we use polling:

1. Schedule Trigger: Every 5 minutes
2. Personio Node: GET /employees
3. Filter: Only employees with start date = today

Step 2: Prepare Data

// Example: Format data for Google Workspace
{
  "email": `${item.first_name.toLowerCase()}.${item.last_name.toLowerCase()}@company.com`,
  "firstName": item.first_name,
  "lastName": item.last_name,
  "department": item.department,
  "manager": item.supervisor_email
}

Step 3: Create Accounts

Execute in parallel:

• Google Admin API - Create user
• Slack API - Send invite
• Jira API - Create ticket

Step 4: Notification

• Email to new employee with credentials
• Slack message to team
• Summary to HR

Step-by-Step: Connect Personio with Make.com

Create Make.com Scenario

Step 1: Choose Trigger

• Personio Module - Watch Employees
• Or: Webhook + Personio HTTP Request

Step 2: Router for Parallelization

• Path 1: IT Systems
• Path 2: Communication
• Path 3: Documentation

Step 3: Connect Modules

• Google Workspace - Create User
• Slack - Send Message
• Jira - Create Issue

Tip: Make.com has native Personio modules, which simplifies setup.
