Personalized communications are powerful. The right message, at the right time, on the right channel is the difference between a customer for life – and a lifelong detractor. Whether you're in real estate, medicine, finance, retail, or really any industry, timely and useful communications are essential to keep your customers happy.
This post will show you how to personalize an SMS to a customer on an e-commerce page using Segment and Twilio Programmable SMS.
Let's build something timely!
Prerequisites
Before we get started, you'll need to sign up for a few accounts.
- Sign up for a Segment Account (if you sign up through this link, you'll get $10 when you upgrade)
- Sign up for a Twilio Account
And with that, let's get started!

If you want to send a single SMS using Twilio you'll need a Twilio account, a phone number to send them from, and of course you'll need to know the destination phone number and the content of the message. Once you have these you can send your message with a single API call either with a direct HTTP request, or using any of our helper libraries. Check out our Programmable SMS Quickstarts for more details.
What if you need to send a hundred messages? Or a thousand? Or even more? In this post I'll talk through the challenges you may face as you scale up and how to get past them. Code samples will be in Java but the same principles apply with any programming language.
Sending a single SMS
Sending one SMS with Java is covered in this blog post. Feel free to go and read it, …

A contact form is a common feature of many websites that provides a way for users to get in touch with the site’s administrators without having to open their email or hop on the phone. In a Python Django application, a contact form can be used to store a user’s contact information in the site’s database. And with Twilio SendGrid, we can also trigger an automated email containing that information as soon as the form is successfully submitted.
In this tutorial, we will build a simple contact form for a Django web application that does just that.

In this tutorial you’ll leverage Twilio Programmable Voice to receive phone calls at your Twilio phone number, and transcribe any voice messages left by the caller. This guide can be used as a foundation to build your own voicemail system.
Prerequisites
To get started with this tutorial, you’ll need the following:
- A free Twilio account (sign up with this link and get $10 in free credit when you upgrade to a paid account)
- A Twilio phone number
Create a new Twilio Functions Service
Through Twilio, you can configure a webhook that will handle any incoming calls to your Twilio phone number.
You’ll need a place to host the code for the webhook - this could be your own server, or locally running application, but for this tutorial you’ll use Twilio Functions. Twilio Functions is a serverless environment that lets you deploy backend services without the overhead of setting …

Twilio is all about powering communication and doing it conveniently and fast in any language. But if you have a Python application written with the asyncio package, it may not be completely clear how to translate the examples from the documentation into non-blocking code that works well with an asynchronous loop.
In this tutorial you’ll learn how to properly deliver SMS notifications from a FastAPI application. The techniques shown here are also applicable to other asyncio frameworks.
Tutorial requirements
- Python 3.6 or newer. If your operating system does not provide a Python interpreter, you can go to python.org to download an installer.

So you've built a video API with Twilio Programmable Video, Node.js, TypeScript, and Express. You've added CORS support so that your future video app will be able to access resources on your server. What's next?
In order for users to actually be able to connect to video rooms in your app, they will need to be authenticated using an access token. In this tutorial, you'll update your Express + TypeScript video API to add a new route that grants access tokens to the users who will be using your video app. Let's get started!
Prerequisites
You will need:
- A free Twilio account. (If you register here, you'll receive $10 in Twilio credit when you upgrade to a paid account!)
- Node.js (version 14.16.1 or higher) and npm installed on your machine.
- HTTPie or cURL.
- The code from the previous tutorial (see below).
The rest of this tutorial builds on …
Imagine you've just built a great API using Node.js, Express, and TypeScript. You've also built a client-side web app and are ready to fire it up in your browser, get it talking to your server, and hopefully share it with the world.
You open up a browser window and navigate to where your app is running, then you pop open the console in your developer tools. Your app makes its first API call to your server...but then, instead of the data you're expecting to see populate your app, you see an error like the one below in your console:
Access to fetch at 'http://localhost:5000/rooms' from origin 'http://localhost:3000'
has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present
on the requested resource. If an opaque response serves your needs, set the
request's mode to 'no-cors' to fetch the resource with CORS disabled.
Yikes! This error is due to Cross-Origin Resource …

Web Speech APIには、音声合成（text to speech）と、音声認識（speech to text）という2つの機能があります。以前の記事では音声合成について解説しましたが、今回はSpeechRecognition APIを利用したブラウザの音声認識、音声書き起こし方法について解説します。
ユーザーが発する音声コマンドを認識できれば、通常よりも没入感のあるインターフェースを提供でき、音声操作を好むユーザーを獲得しやすくなります。2018年のGoogleの報告によると、全世界のオンライン人口のうち27%がモバイルデバイスで音声検索を使用しています。今回解説するブラウザの音声認識機能を用いて、あなたのWebアプリケーションで基本的な音声検索からインタラクティブbotまで、多岐にわたる機能を提供できます。
次のセクションからAPIのしくみを理解し、何ができるか実際に確認してみましょう。
必要なもの
APIを実際に体験できるサンプルアプリケーションを作成するために次のツールを用意します。
- Google Chrome
- テキストエディタ
今回はHTML、CSS、JavaScriptを使用してアプリケーションを作成します。作業用の新しいディレクトリを作成し、このディレクトリにstarter HTMLとCSSを保存します。保存したHTMLファイルをブラウザで開くと以下のスクリーンショットと同じ画面が表示されます。
