A Leave Request Processor on n8n that validates employee identity, checks leave balances, makes an approval decision and notifies the employee automatically. No back-and-forth emails. No waiting for a manager to remember to respond. No HR team manually cross-checking spreadsheets. Day 24 of my 30-Day Automation Challenge (Tools: n8n, Gmail, Goggle Sheets) Here is exactly how the workflow operates: 📋 New Leave Request Trigger fires the moment a new leave request row is added to Google Sheets 🔍 Validate Employee ID and Calculate Leave Days node verifies the submission and calculates the number of leave days being requested ✅ Check if Employee ID is Valid node confirms whether the requesting employee exists in the system and routes accordingly If the Employee ID is Invalid: 📧 Send Mail for Invalid ID node immediately fires an email notifying the requester that their submission could not be processed due to an unrecognized employee ID. If the Employee ID is Valid: 📊 Get Leave Balance node reads the employee’s current leave balance from Google Sheets checking how many days they have remaining 🔀 If You Still Have Leave Days Accrued node checks whether the requested days fall within the available balance and routes to the correct outcome If Leave Balance is Sufficient: ✅ Leave Request Approved node sends a personalized approval email to the employee confirming their leave has been granted If Leave Balance is Insufficient: ❌ Leave Request Denied node sends a professional email informing the employee that their request cannot be approved due to insufficient leave days remaining Request submitted. Identity verified. Balance checked. Decision made. Employee notified. All automatically. What makes this workflow genuinely valuable is the logic chain. It is not simply approving or rejecting requests randomly. It is making a structured decision based on real data. Is this a valid employee? Do they have enough leave days? The answers to those two questions determine the entire outcome and the workflow handles both gracefully with appropriate communication at every stage. The Invalid ID path is the detail that most basic leave systems miss entirely. When an unrecognized submission comes through, the workflow does not stall or fail silently. It immediately notifies the requester so they can correct and resubmit. That kind of graceful error handling is what makes automation trustworthy in a real HR environment. Replicating @DDataknight build today was a reminder that learning by doing is always more valuable than learning by watching. Following the logic, connecting the nodes and making it run cleanly yourself is how the understanding becomes permanent. Think about every growing business managing leave requests manually. HR managers receiving WhatsApp messages asking for approval. Employees following up repeatedly because they are not sure if their request was seen. Managers cross-checking spreadsheets to remember how many days someone has left. All of that friction disappears with this workflow. Does your organization process leave requests manually or do you have a system that handles approvals automatically? I would genuinely love to know how your HR team currently manages this below. #WorkflowAutomation #n8n #Revobridge #30DayChallenge #HRAutomation #BuildinPublic
