Retell AI Hello World

Overview

Minimal working example demonstrating core Retell AI functionality.

Prerequisites

• Completed retellai-install-auth setup
• Valid API credentials configured
• Development environment ready

Instructions

Step 1: Create Entry File

Create a new file for your hello world example.

Step 2: Import and Initialize Client

import { RetellAIClient } from '@retellai/sdk';

const client = new RetellAIClient({
  apiKey: process.env.RETELLAI_API_KEY,
});

Step 3: Make Your First API Call

async function main() {
  // Your first API call here
}

main().catch(console.error);

Output

• Working code file with Retell AI client initialization
• Successful API response confirming connection
• Console output showing:

Success! Your Retell AI connection is working.

Error Handling

Error	Cause	Solution
Import Error	SDK not installed	Verify with npm list or pip show
Auth Error	Invalid credentials	Check environment variable is set
Timeout	Network issues	Increase timeout or check connectivity
Rate Limit	Too many requests	Wait and retry with exponential backoff

Examples

TypeScript Example

import { RetellAIClient } from '@retellai/sdk';

const client = new RetellAIClient({
  apiKey: process.env.RETELLAI_API_KEY,
});

async function main() {
  // Your first API call here
}

main().catch(console.error);

Python Example

from retellai import RetellAIClient

client = RetellAIClient()

# Your first API call here
