A free template is on the way, too. "Inquiry → LINE notification" pings you on LINE whenever a website form or Gmail inquiry arrives. We'll send it to IsauLab Weekly subscribers when it's ready.

Every template includes

  • The workflow file (JSON)
  • A setup guide with screenshots (Japanese & English, PDF)
  • Sample data for testing
  • A security checklist: which permissions to grant and how to revoke them

Before you buy

  • You'll need n8n (n8n Cloud or self-hosted).
  • You connect your own LINE, Google and other accounts. Templates never contain IsauLab credentials.
  • AI editions need your own AI provider API key (usage fees are yours).
  • Posting Google review replies automatically requires applying for Google Business Profile API access.
  • We plan to sell through BOOTH (Japan) and Lemon Squeezy (international).
