Twilio Agent Connect AWS

AWS integrations for Twilio Agent Connect — connect AWS agent services to Twilio's communication channels.

Documentation ◆ API Reference ◆ Python SDK ◆ Examples ◆ Deployment

AWS-specific connectors for Twilio Agent Connect (TAC), enabling seamless integration with AWS agent services like Strands, Bedrock Agents, and Bedrock AgentCore.

---

Features

Agent Runtime Integration

• AWS Strands SDK - Build conversational agents with persistent session management and context-aware configuration
• AWS Bedrock Agents - Connect console-created agents with managed action groups and knowledge bases
• AWS Bedrock AgentCore - Deploy custom agent code (any framework: Strands, LangGraph, OpenAI SDK) with managed runtime
  • Lambda Deployment ⭐ Recommended - Serverless deployment with Lambda Function URL webhook proxy (no container infrastructure)
  • Fargate Deployment - Container-based deployment with BedrockAgentCoreConnector and FastAPI server on AWS Fargate

Multi-Channel Communication

• Voice and SMS support - Single codebase handles both phone calls and text messages
• Automatic conversation routing - Messages route to the correct agent instance per conversation
• Memory injection - Customer history and preferences automatically included in agent context

Deployment Options

• FastAPI server - Production-ready server with AWS ALB optimization and ngrok support for local testing (Fargate deployments)
• Lambda Function URL proxy - Serverless webhook handler with Twilio signature validation for AgentCore deployments
• AgentCore runtime integration - Server adapter for Bedrock AgentCore with HTTP (SMS) and WebSocket (voice) support

Production Ready

• Twilio webhook validation - Automatic signature verification for secure integrations
• Session persistence - Continue conversations across interactions with built-in session management
• Error handling - Robust error handling and fallbacks for production reliability

Installation

With Strands SDK

pip install twilio-agent-connect-aws[strands,server]

With Bedrock Agents

pip install twilio-agent-connect-aws[bedrock,server]

With Bedrock AgentCore

pip install twilio-agent-connect-aws[agentcore,server]

Development

# Install with development tools (includes all connectors)
pip install twilio-agent-connect-aws[dev]

Configuration

twilio-agent-connect-aws requires TAC environment variables. See TAC Configuration for details.

Required Environment Variables

# Twilio Configuration
TWILIO_ACCOUNT_SID=your_account_sid
TWILIO_AUTH_TOKEN=your_auth_token
TWILIO_API_KEY=your_api_key          # Starts with SK
TWILIO_API_SECRET=your_api_secret    # Secret for API key
TWILIO_PHONE_NUMBER=+1234567890
TWILIO_CONVERSATION_CONFIGURATION_ID=conv_configuration_xxx

# Server Configuration (for Voice)
TWILIO_VOICE_PUBLIC_DOMAIN=your-domain.ngrok.io

Examples

Full examples available in getting_started/examples/:

• strands_agents.py - Strands SDK with per-conversation agent management
• bedrock_agents.py - AWS Bedrock Agents (console-created agents)
• bedrock_agentcore_agents.py - AWS Bedrock AgentCore (custom agent code deployment)

Deployment

See the deployment guides for production deployment options:

Container-based (Fargate)

• Strands on Fargate - Deploy Strands SDK agents with FastAPI server
• Bedrock Agents on Fargate - Deploy console-created Bedrock agents
• AgentCore Connector on Fargate - Deploy custom agent code with BedrockAgentCoreConnector and FastAPI server
  • Full control over server configuration
  • Use TAC connectors for multi-channel management

Serverless (Lambda) ⭐ Recommended for AgentCore

• AgentCore with Lambda - Deploy AgentCore runtime with Lambda Function URL webhook proxy
  • No container infrastructure required
  • Automatic scaling with Lambda and AgentCore
  • Simpler deployment and lower operational overhead
  • Uses AgentCoreLambdaProxy and TACAgentCoreApp utilities
  • See deploy/agentcore_aws_lambda/ for setup guide
