[syed.atyab.hussain@gmail.com] Hello, New Teammate! – Build a One-Click Onboarding Greeting in n8n

[CodelineAtyab]

📝 User Story

As a Product Owner,
I want my team to build an n8n workflow that automatically creates and posts a friendly welcome message whenever a new employee submits their onboarding form,
so that newcomers feel acknowledged immediately and the team saves time on manual greetings.

---

✅ Acceptance Criteria

#	Criterion	Details
1	Environment Setup	• Clone the n8n-hosting repository. • Run docker-compose up. • n8n launches on localhost with PostgreSQL successfully.
2	Workflow Trigger	• Trigger type: HTTP Webhook (or Google Form integration). • Incoming JSON must contain at minimum: fullName, role, startDate.
3	Date Formatting	• A Function node converts startDate into a human-readable phrase  (e.g., “next Monday”).
4	LLM Personalization	• A Claude 3.7/4 node is invoked with the form data. • Returns a personalized, upbeat welcome message. • If any field is missing, the LLM supplies a sensible default.
5	Channel Posting	• The generated message is posted automatically to a designated Slack (or Microsoft Teams) channel. • Uses an existing credential stored in n8n.
6	Error Handling	• If the Claude call fails: – Workflow logs the error. – Sends an email alert to the admin address configured in n8n.
7	Performance	• Running the workflow with sample input results in the formatted welcome message appearing in the channel within 30 seconds, with no manual intervention required.

🔧 Technical Notes & Recommendations

• Security: Store API keys and credentials in n8n’s encrypted credential manager.
• Testing: Include unit tests for the Function node’s date conversion logic.
• Monitoring: Consider adding an additional logging node (e.g., DataDog, Loggly) for long-term observability.
• Scalability: Use environment variables for Slack/Teams channel IDs to support multiple teams.
