Bridge Two-Way SMS Conversations into WhatsApp
Customers text your Twilio number and the agent relays the conversation into your WhatsApp so you can respond from one place. SMS replies go back through Twilio automatically.
Conversation example
New SMS from a customer. Relaying to your WhatsApp...
SMS relay active: From: +1 510 555 0244 (Jennifer K., Lite plan customer since Jan) Message: 'Hey, my invoice shows the old price — can you refund $20?' Context I pulled from Stripe: - Jennifer was grandfathered at $5 but last invoice was $10 - That billing error affected 14 customers, already flagged - Refund of $5 (not $20) is the correct fix When you reply on WhatsApp, I will forward your reply back to Jennifer as SMS via Twilio with your signature. Drafted this for you: 'Hi Jennifer, sorry for the confusion — I refunded $5 to your card (that matches your grandfathered price). It should land in 3-5 days.' Want me to send it?
More Twilio use cases
SMS Alerts for High-Priority Events
Some events need to wake someone up, not just ping WhatsApp. The agent sends an SMS via Twilio for the most urgent alerts and falls back to voice if there is no reply in 5 minutes.
Voice Call Cascade When WhatsApp Is Unread
If a WhatsApp alert goes unread for 5 minutes during an incident, the agent makes an actual phone call via Twilio with a text-to-speech briefing and a DTMF acknowledge key.
OTP Verification with Twilio Verify
The agent runs your entire OTP verification flow via Twilio Verify — send code, handle retries, check attempts, and enforce rate limits — from simple chat instructions.
Daily Twilio Messaging Cost Report
Every morning the agent pulls your Twilio usage records, breaks down cost by number and message type, flags anomalies, and delivers a report on WhatsApp.
Automated Two-Way SMS Customer Conversations
The agent handles full SMS conversations with customers — answering billing questions, updating addresses, rescheduling appointments — and only escalates to WhatsApp when a human is truly needed.
