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);

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
