    How to Collect Times and Dates in Voice Calls or SMS using JavaScript How to Collect Times and Dates in Voice Calls or SMS using JavaScript

    Twilio offers a wide variety of channels you can use to connect with your customers, for example, through an SMS or Phone Call. One of the ways you can use these channels is to collect data from your customers. Depending on the type of data, this can be a complex undertaking. Collecting individual words or numbers is usually pretty straightforward. However, when asking customers to share specific Times and Dates, this can be far more complex. A typical use-case might be the scheduling of an appointment. This is especially true when allowing customers to communicate in free form (for example, “I would like an appointment next Tuesday at 3 pm”).

    In this blog, I will show you how you can extract Times and Dates during a phone call using JavaScript and serverless Twilio Functions without the need for any 3rd party integrations.

    MMS for Long Text Messages is Generally Available MMS for Long Text Messages

    In certain instances, businesses need to send longer text messages to communicate effectively. Perhaps it’s a doctor’s office sending post-appointment care notes or a retailer sending a promotion that includes emojis. But the increased character counts in such messages can cause them to be sent across several text messages (segments) which may diminish the recipient's experience and increase costs.

    That’s why we’re excited to announce that MMS for Long Text Messages is now generally available!

    This feature allows Twilio customers to deliver those longer messages to their recipients via a single MMS message instead of it being broken up into smaller SMS segments. MMS for Long Text Messages is available at no additional cost as part of our Messaging Services features. It is available in the US and Canada and can be used with Short Code, Toll-Free, and A2P 10DLC sender types.

    This is another step in …

    Introducing the Twilio Dev Phone dev-phone-banner

    I used to be an adjunct professor at Berkeley City College. My class was learning about 3rd party APIs, and so I set aside a classroom day to work on Twilioquest. On the day of the event, my students showed up and fired up their laptops...

    And I learned that my classroom had no cell service.

    While it was funny to watch my students run outside to a window to try and get some service and "catch" the text message, situations like this show us a clear issue: sometimes, our personal cell phones can be a blocker to our Twilio development. That's why Twilio's Developer Advocacy team is excited to announce the Twilio Dev Phone, a Twilio CLI plugin that allows you to send and receive calls and SMS straight from your local development environment.

    How to better configure C# and .NET applications for Twilio How to better configure C# and .NET apps for Twilio

    There are a hundred different ways to provide configuration to your applications. For almost any programming language, you can use environment variables and .env files, but configuration can also be stored in other file formats like JSON, YAML, TOML, XML, INI, and the list keeps on going. Though, in some scenarios configuration isn't pulled from files, but instead is pulled from a service like Azure Key Vault, HashiCorp Vault, or a similar vault service. It is rare that your configuration will come from a single source. Luckily, there are APIs in .NET that can help you grab configuration from multiple sources and merge them together.

    In this tutorial, you'll start with an application that sends text messages using Twilio Programmable SMS, where the configuration is fetched directly from the environment variables. You'll then refactor the app to

    What's new in the Twilio helper library for ASP.NET (v5.73.0 - April 2022) What's new in the Twilio helper library for ASP.NET (v5.73.0 - April 2022)

    The Twilio helper library for ASP.NET (Twilio.AspNet) is a community-driven open-source project to make integrating Twilio with ASP.NET easier, for both ASP.NET Core and ASP.NET MVC on .NET Framework. The library helps you with very common use cases like:

    • Responding to Twilio webhook requests with TwiML objects from the official Twilio SDK for C# and .NET.
    • Binding data from Twilio webhook requests to strongly typed .NET objects.
    • Validating webhook requests originate from Twilio and rejecting them if not.

    As .NET and ASP.NET is evolving, the Twilio.AspNet contributors are enhancing the library to take advantage of the newest capabilities and best practices. So what's new?

    What's old in Twilio.AspNet

    Actually, before I share the shiny new additions, let me share what is already part of the library. After all, this is the first blog post to share news about the library.

    Handle Twilio webhook requests with ASP.NET

    In previous versions …
