This guide walks through the fastest possible path: install an SDK, paste your credentials, and call CreateMessage to send a real SMS to your phone.

What You NeedCopy Anchor Link

Step 1 — Install the SDKCopy Anchor Link

Pick your language. The portal defaults to TypeScript; you can change languages with the selector on any code page.

npm install twilio-api-sdk

For full setup instructions per language — including authentication helpers and project scaffolding — see the Seting Up SDKs page

Step 2 — Configure CredentialsCopy Anchor Link

Replace YOUR_ACCOUNT_SID and YOUR_AUTH_TOKEN with the values from your Twilio Console.

export TWILIO_ACCOUNT_SID="ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
export TWILIO_AUTH_TOKEN="your_auth_token_here"

Step 3 — Send the SMSCopy Anchor Link

import { Client } from 'twilio-api-sdk';

const client = new Client({
  basicAuthCredentials: {
    username: process.env.TWILIO_ACCOUNT_SID!,
    password: process.env.TWILIO_AUTH_TOKEN!,
  },
});

const accountSid = process.env.TWILIO_ACCOUNT_SID!;
const to         = '+15555550123';                  // your verified phone number
const from       = '+15005550006';                  // your Twilio number
const body       = 'Hello from Twilio + APIMatic!';

const response = await client.smsApi.createMessage(
  accountSid, to,
  undefined, undefined, undefined, undefined, undefined, undefined, undefined,
  undefined, undefined, undefined, undefined, undefined, undefined, undefined,
  undefined, undefined, undefined, undefined,
  from, undefined, body,
);

console.log('Sent! SID:', response.result.sid);

If everything is wired up, you'll get a JSON response with a sid starting with SM… — and within a few seconds, an SMS will arrive on the destination phone.

Try It in the PlaygroundCopy Anchor Link

Prefer not to install anything? Open the Live API Playground on the Create Message endpoint, paste your credentials, and run the call directly from your browser.
