Twilio SMS Messaging Help
Overview
I'm building an SMS reminder system using Twilio in n8n where agents receive reminders about missing documents for multiple properties. When agents reply via SMS, I cannot identify which property/conversation the reply is referring to because the Message SID changes with each message, breaking conversation continuity.
Business Context
- Real estate agents manage multiple properties simultaneously
- Agents receive SMS reminders about missing documents for different properties
- A single agent can be reminded about 3-5+ properties in the same day
- When an agent replies "I'll send it tomorrow", I need to know: Which property are they referring to?
Current Workflow
Outbound SMS Flow (Working)
- n8n identifies properties with missing documents
- HTTP Request node sends SMS via Twilio API to agent
- SMS content: "Hi [Agent], missing documents for [Property Address]. Please upload by [Date]."
- Twilio returns Message SID (e.g., SM123abc...)
- Message SID stored in database/Google Sheets
Inbound SMS Flow (Broken)
- Agent replies: "I'll send the documents tonight"
- Twilio webhook triggers n8n with new Message SID (e.g., SM456def...)
- Problem: New Message SID has no relationship to original outbound Message SID
- Cannot determine: Which property reminder is this reply for?
Attempt : Phone Number Only
- Match based on agent phone number alone
- Failed: Doesn't work when agent has multiple pending properties
Ideal Solution Criteria
- Automatically link SMS replies to specific property reminders
- Work reliably even with multiple pending reminders
- Minimal friction for agents (simple reply, not complex codes)
- Scalable across hundreds of agents and properties
- Maintain conversation history for audit trail
