Review and approve Google Sheets orders by email and notify via LINE

Description

Automatically processes new orders added to Google Sheets. Small orders are approved instantly; large orders trigger an HTML email with one-click Approve / Reject links — each handled by an independent webhook, so multiple orders can be reviewed simultaneously without blocking each other. What makes this different Unlike Wait-node designs that block when multiple orders queue up, this workflow uses a stateless token pattern: each order gets a unique token written back to the sheet. Approval links carry the token; the handler validates it on every click — safe, idempotent, and fully concurrent. Key features Google Sheets Trigger polls for new rows automatically — no external caller needed Configurable approval threshold (default: 500) Duplicate-processing guard: skips rows that already have a status One-click Approve / Reject email with styled HTML buttons Token validation: tampered or expired links return a 403 error page Already-processed guard: clicking the same link twice shows a friendly message LINE push notification for every outcome (auto-approved, approved, rejected) All results written back to Google Sheets with a reviewedAt timestamp Integrations Google Sheets · Gmail · LINE Messaging API · n8n Webhook Required sheet columns orderId · customerName · amount · approvalToken · status 💡 Want more automation templates? 👉 https://jasonchuang0818.gumroad.com/l/n8n-content-automation-bundle.
