Retell AI Multi Env Setup

Overview

Implementation patterns for Retell AI multi env setup — voice agent and telephony platform.

Prerequisites

• Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern

import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);

Output

• Retell AI integration for multi env setup

Error Handling

Error	Cause	Solution
401 Unauthorized	Invalid API key	Check RETELL_API_KEY
429 Rate Limited	Too many requests	Implement backoff
400 Bad Request	Invalid parameters	Check API documentation

Examples

Keep development and production credentials separated

Create distinct Retell projects or explicitly named agent groups for development, staging, and production. Each environment receives its own secret reference and phone routing configuration, so a local test cannot accidentally create a live call. Verify the separation by listing agents with the development credential and confirming that production identifiers are absent; promote configuration through a controlled CI environment instead of copying keys between files.
