Delete the “Sample Data Generator” node 1. Add “Google Sheets” node 1. Connect to your Google account 1. Configure these settings: - Operation: Read - Document: Your employee spreadsheet - Sheet: Employee data sheet - Range: A1:K100 (adjust for your data size) - Options: ✅ RAW data, ✅ Header row Step 3: Map Your Data Add a “Set” node after Google Sheets to standardize field names: Option 2: HRIS Integration (BambooHR Example) Step 1: BambooHR API Setup 1. Get your BambooHR API key from Settings > API Keys 1. Note your company subdomain (e.g., yourcompany.bamboohr.com) Step 2: Replace Sample Data Generator 1. Delete the “Sample Data Generator” node 1. Add “HTTP Request” node 1. Configure these settings: - Method: GET - URL: - Authentication: Basic Auth - Username: Your API key - Password: x (leave as ‘x’) - Headers: Accept: application/json Step 3: Transform BambooHR Data Add a “Code” node to transform the API response: Option 3: CSV File Upload Step 1: Prepare CSV File Create a CSV with the same structure as the Google Sheets format. Step 2: Use CSV Parser 1. Replace “Sample Data Generator” with “Read Binary File” node 1. Add “CSV Parser” node 1. Configure settings: - Include Headers: Yes - Delimiter: Comma - Skip Empty Lines: Yes ----- 📧 Output Integration Setup Email Notifications Step 1: Add Email Node 1. Add “Email” node after “Reminder Scheduler” 1. Connect to your email provider (Gmail/Outlook) Step 2: Configure Email Templates Slack Integration Step 1: Add Slack Node 1.
