Retell AI Install Auth

Overview

Install the Retell AI SDK and configure API key authentication for building voice agents.

Prerequisites

Retell AI account at retellai.com
API key from the Retell AI dashboard
Node.js 18+ or Python 3.9+

Instructions

Step 1: Install SDK

set -euo pipefail
# Node.js
npm install retell-sdk
 
# Python
pip install retell-sdk

Step 2: Configure Environment

# .env

Step 3: Initialize Client (Node.js)

import Retell from 'retell-sdk';
 
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });
 
// Verify connection — list agents
const agents = await retell.agent.list();
console.log(`Connected! ${agents.length} agent(s) configured.`);

Step 4: Initialize Client (Python)

from retell import Retell
import os
 
retell = Retell(api_key=os.environ["RETELL_API_KEY"])
agents = retell.agent.list()
print(f"Connected! {len(agents)} agent(s) configured.")

Output
