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

Prerequisites

• Retell AI account at retellai.com

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.`);

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.")
