We’re building a production-ready AI automation system using: • n8n • Twilio (SMS + missed call handling) • Notion CRM • Stripe • Jobber (optional) • OpenAI API Before proceeding, I’d like to understand your approach. Specifically: How would you structure a scalable n8n workflow that handles: Inbound SMS Lead creation/update in Notion Conditional data validation Automated follow-up SMS Deal → Quote → Job lifecycle How do you handle: Error handling Logging Retry logic Rate limits Webhook failures Can you share an example of a similar production workflow you’ve built in n8n? We are not looking for a simple Zapier-style flow. We want something clean, modular, and scalable. Looking forward to your thoughts.
