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
