ElevenLabs Agents Platform
Build voice AI agents with natural conversations, multiple LLM providers, custom tools, and easy web embedding.
Setup: See Installation Guide for CLI and SDK setup.
Quick Start with CLI
The ElevenLabs CLI is the recommended way to create and manage agents:
# Install CLI and authenticate
npm install -g @elevenlabs/cli
elevenlabs auth login
# Initialize project and create an agent
elevenlabs agents init
elevenlabs agents add "My Assistant" --template complete
# Push to ElevenLabs platform
elevenlabs agents push
Available templates: complete, minimal, voice-only, text-only, customer-service, assistant
Python
from elevenlabs import ElevenLabs
client = ElevenLabs()
agent = client.conversational_ai.agents.create(
name="My Assistant",
enable_versioning=True,
conversation_config={
"agent": {
"first_message": "Hello! How can I help?",
"language": "en",
"prompt": {
"prompt": "You are a helpful assistant. Be concise and friendly.",
"llm": "gemini-2.0-flash",
"temperature": 0.7
}
},
"tts": {"voice_id": "JBFqnCBsd6RMkjVDRZzb"}
}
)
JavaScript
import { ElevenLabsClient } from "@elevenlabs/elevenlabs-js";
const client = new ElevenLabsClient();
const agent = await client.conversationalAi.agents.create({
name: "My Assistant",
enableVersioning: true,
conversationConfig: {
agent: {
firstMessage: "Hello! How can I help?",
language: "en",
prompt: {
prompt: "You are a helpful assistant.",
llm: "gemini-2.0-flash",
temperature: 0.7
}
},
tts: { voiceId: "JBFqnCBsd6RMkjVDRZzb" }
}
});
cURL
curl -X POST "https://api.elevenlabs.io/v1/convai/agents/create?enable_versioning=true" \
-H "xi-api-key: $ELEVENLABS_API_KEY" -H "Content-Type: application/json" \

Starting Conversations
Server-side (Python): Get signed URL for client connection:
signed_url = client.conversational_ai.conversations.get_signed_url(
agent_id="your-agent-id",
environment="staging",
)
Client-side (JavaScript):
import { Conversation } from "@elevenlabs/client";
const conversation = await Conversation.startSession({
agentId: "your-agent-id",
environment: "staging",
onMessage: (msg) => console.log("Agent:", msg.message),
onUserTranscript: (t) => console.log("User:", t.message),
onError: (e) => console.error(e)
});
React Hook:
import { useConversation } from "@elevenlabs/react";
const conversation = useConversation({ onMessage: (msg) => console.log(msg) });
// Get a signed URL for the target environment from your backend, then:
await conversation.startSession({ signedUrl: token });

Turn eagerness: patient (waits longer for user to finish), normal, or eager (responds quickly)
See Agent Configuration for all options.
Tools
Extend agents with webhook, client, or built-in system tools. Tools are defined inside conversation_config.agent.prompt:
Workspace environment variables can resolve per-environment server tool URLs, headers, and auth connections, and runtime system variables such as {{system__conversation_history}} can pass full conversation context into tool calls when needed.
"prompt": {
"prompt": "You are a helpful assistant that can check the weather.",
"llm": "gemini-2.0-flash",
"tools": [
# Webhook: server-side API call
{"type": "webhook", "name": "get_weather", "description": "Get weather",
"api_schema": {"url": "https://api.example.com/weather", "method": "POST",
"request_body_schema": {"type": "object", "properties": {"location": {"type": "string"}}, "required": ["location"]}}},
# Client: runs in the browser
{"type": "client", "name": "show_product", "description": "Display a product",
"parameters": {"type": "object", "properties": {"productId": {"type": "string"}}, "required": ["productId"]}}
],
"built_in_tools": {
"end_call": {},
"transfer_to_number": {"transfers": [{"transfer_destination": {"type": "phone", "phone_number": "+1234567890"}, "condition": "User asks for human support"}]}
}
}
Client tools run in browser:
clientTools: {
show_product: async ({ productId }) => {
document.getElementById("product").src = `/products/${productId}`;
return { success: true };
}
}
See Client Tools Reference for complete documentation.
Widget Embedding
<elevenlabs-convai agent-id="your-agent-id"></elevenlabs-convai>
<script src="https://unpkg.com/@elevenlabs/convai-widget-embed" async type="text/javascript"></script>
Customize with attributes: avatar-image-url, action-text, start-call-text, end-call-text.
See Widget Embedding Reference for all options.
Outbound Calls
Make outbound phone calls using your agent via Twilio integration:
Python
response = client.conversational_ai.twilio.outbound_call(
agent_id="your-agent-id",
agent_phone_number_id="your-phone-number-id",
to_number="+1234567890",
call_recording_enabled=True
)
print(f"Call initiated: {response.conversation_id}")
JavaScript
const response = await client.conversationalAi.twilio.outboundCall({
agentId: "your-agent-id",
agentPhoneNumberId: "your-phone-number-id",
toNumber: "+1234567890",
callRecordingEnabled: true,
});
cURL
curl -X POST "https://api.elevenlabs.io/v1/convai/twilio/outbound-call" \
-H "xi-api-key: $ELEVENLABS_API_KEY" -H "Content-Type: application/json" \
-d '{"agent_id": "your-agent-id", "agent_phone_number_id": "your-phone-number-id", "to_number": "+1234567890", "call_recording_enabled": true}'
See Outbound Calls Reference for configuration overrides and dynamic variables.
Managing Agents
Using CLI (Recommended)
# List agents and check status
elevenlabs agents list
elevenlabs agents status
# Import agents from platform to local config
elevenlabs agents pull # Import all agents
elevenlabs agents pull --agent <agent-id> # Import specific agent
# Push local changes to platform
elevenlabs agents push # Upload configurations
elevenlabs agents push --dry-run # Preview changes first
# Add tools
elevenlabs tools add-webhook "Weather API"
elevenlabs tools add-client "UI Tool"
Project Structure
The CLI creates a project structure for managing agents:
your_project/
├── agents.json # Agent definitions
├── tools.json # Tool configurations
├── tests.json # Test configurations
├── agent_configs/ # Individual agent configs
├── tool_configs/ # Individual tool configs
└── test_configs/ # Individual test configs
SDK Examples
# List
agents = client.conversational_ai.agents.list()
# Get
agent = client.conversational_ai.agents.get(agent_id="your-agent-id")
# Update (partial - only include fields to change)
client.conversational_ai.agents.update(agent_id="your-agent-id", name="New Name")
client.conversational_ai.agents.update(agent_id="your-agent-id",
conversation_config={
"agent": {"prompt": {"prompt": "New instructions", "llm": "claude-sonnet-4"}}
})
# Delete
client.conversational_ai.agents.delete(agent_id="your-agent-id")
See Agent Configuration for all configuration options and SDK examples.
Error Handling
try:
agent = client.conversational_ai.agents.create(...)
except Exception as e:
print(f"API error: {e}")
Common errors: 401 (invalid key), 404 (not found), 422 (invalid config), 429 (rate limit)
