Social Intents integrates with Twilio to add SMS as a customer communication channel. Customers text your Twilio phone number, and messages are routed to your team in Microsoft Teams, Slack, Google Chat, or the web inbox - the same way as website chats and WhatsApp conversations.
Prerequisites
- A Twilio account (twilio.com)
- A Twilio phone number with SMS capability
- Your Twilio Account SID and Auth Token (found in the Twilio Console dashboard)
- A Social Intents chat widget connected to a team platform
Setup
Enter Twilio Credentials
Go to Settings > Channels and expand SMS (Twilio). Enter your Twilio Account SID, Twilio auth token, and the number you purchased in Send-from number using E.164 format. If you use a Twilio Messaging Service, add its SID in Messaging Service SID (optional). You can also reach this section from Integrations > SMS card > Set up.
Set the Webhook URL
Social Intents shows the exact webhook URL for your account in Settings > Channels > SMS (Twilio) under Twilio webhook URL, with a Copy button. In your Twilio Console, open your phone number settings and paste it as the incoming message webhook. It has this form:
https://www.socialintents.com/v1/api/twilio/chat/{YOUR_WIDGET_ID}Replace {YOUR_WIDGET_ID} with your Social Intents widget ID. Set the method to POST.
Route to a Widget
In the same SMS (Twilio) section, use Route SMS chats to to select the widget that handles SMS conversations. This determines which team channel or space receives the messages.
Configure Session Settings
Set the auto-close interval for inactive SMS conversations and configure any outbound compose preferences.
Test
Send a text message from your personal phone to your Twilio number. The message should appear in your team platform within seconds.
How SMS Conversations Work
- A customer sends a text message to your Twilio phone number
- Twilio forwards the message to Social Intents via webhook
- Social Intents routes it to your connected platform as a new conversation
- Agents reply from Teams, Slack, Google Chat, or the web inbox
- Social Intents sends the reply back to the customer as an SMS via the Twilio API
The agent experience is the same as handling any other conversation - the only difference is a label indicating the source is SMS.

All chatbot features work the same as website chat - custom training data, AI actions, escalation to human agents, and conversation context. Configure your chatbot on the widget's AI Agent tab.
