    Introducing Twilio’s OpenAPI Specification Beta Introducing Twilio's OpenAPI Specification Beta

    Whether you are building your first product with Twilio or looking to expand your product offering, you need easy access to tools in the programming languages or environments you use. Today, we are excited to announce that we have open-sourced an OpenAPI specification in Beta for every Twilio API.

    For a long time we’ve supported and maintained helper libraries and tooling in a handful of the most popular languages and environments used by developers. We’re now expanding that coverage by providing Twilio API documentation files in accordance with the OpenAPI Specification, an industry-standard format for APIs. This makes it simple for you to auto-generate code so you can easily build with Twilio no matter the language or tools you use.

    What you can do with OpenAPI?

    Client Library Generation

    Using the power of the Twilio OpenAPI specification and open-sourced OpenAPI generator, you can now generate new client libraries. …

    How to send SMS at scale with Twilio Title: How to send SMS at scale with Twilio

    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.

    Engineering Improvements to Prevent Service Disruptions Engineering improvements to prevent service disruptions

    Twilio suffered a service disruption on Feb 26, 2021. 

    When we fall short, as we did with the service disruption on Feb 26th 2021, it motivates us to learn and to make our services more resilient and reliable. Nothing is more important than regaining your trust. We want the opportunity to show that Twilio can and will be a reliable and consistent partner. 

    We also want to revive our commitment to you that when an incident occurs that disrupts your customer communications, we will always tell you about it. “No shenanigans” is our ethos.

    Build a Contact Form for a Python Django Application with Twilio SendGrid Build a Contact Form for a Python Django Application with Twilio SendGrid

    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.

    Introducing Python Developer for Technical Content, August Allard augustallard.png

    Ask just about any programmer why they like to write code, and I’ll bet you a giant slice of chocolate cake that every single person will give at least one of these answers:

    • “I love making things!”
    • “I love learning how things work!”
    • “I love solving problems!”

    Of course, this isn’t an exhaustive list of the reasons why people like to write code, but the exclamations in this list have reliably and recurrently come up when I get into conversations with fellow developers. Often, these developers will tell me that not only do they love making things, love learning how things work, or love solving problems, they have actually always enjoyed these things, even in their childhood.

    This unique collection of interests — building, learning, solving — is the longstanding core of my identity.

    In elementary school, Mrs. Elliott was my daycare provider and watched over me …
