# TwiML Bins

## TwiML Bins

TwiML Bins are a serverless solution that help you provide Twilio-hosted instructions to your Twilio applications. They're a useful way to prototype and explore Twilio capabilities without needing to set up your own web server to respond to requests.

## Tutorial

```xml !sample
<Response>
  <Message>Hello, {{From}}! You wrote: "{{ Body }}"</Message>
</Response>
```

1. Twilio manages hosting, scaling, and responding to Voice and Messaging webhooks using your TwiML
2. Write Twilio's Markup Language (TwiML) and use templating using Handlebars
3. Your code responds to traffic and scales effortlessly

Tutorial code output: "Hello, +2134567890. You wrote: 'How are you?'"

Output label: "Hello"

## Get started

You can use Twilio's Markup Language (TwiML) to instruct Twilio what to do when you've an incoming message, or what should happen during a phone call. With TwiML Bins, you can host any valid TwiML directly with Twilio, and Twilio will handle hosting and scaling as you launch your app.

## Voice TwiML

```xml
<Response>
  <Say>Hello from Twilio! We'll be connecting you.</Say>
  <Dial>
    <Number>+12065551212</Number>
  </Dial>
</Response>
```

## Messaging TwiML

```xml
<Response>
  <Message to="+12065551212">
    {{From}} wrote the following: "{{Body}}"
  </Message>
</Response>
```
