We’re excited to announce the official launch of the new Telnyx API, which is now out of beta and ready for action. The new API has been designed for fast, seamless integration and effortless scaling.


Whether you’re introducing voice and messaging capabilities to better engage customers, secure their data, or connect teams globally — you’ll now be able to access SDKs in your favourite programming languages, as well as robust documentation to help you build exactly what you need, faster.


The shiny new Telnyx API covers SIP Trunking, Numbers, Messaging and Call Control, and includes five SDK’s — Python, Node, Ruby, PHP and .NET, with more to come in the near future. These API wrappers mean you can easily integrate with the Telnyx API without having to build RESTful requests for each interaction. This, along with consistent API formatting and behaviour means a faster, more streamlined go-to-market.


Not only is the new API easier to use, it’s also highly performant. To more effectively load balance traffic across our infrastructure, we’ve deployed an edge proxy across multiple regions in the US. And, several ingress points across the country, combined with more machine power per region means that we’ve been able to deliver consistently lower latency levels.


Telnyx can receive inputs from an application anywhere in the world, act on them, and provide webhooks back to those applications in a fraction of a second. The result? A smoother, faster experience for your end users.


In building the new API, our team of engineers have also completely redesigned the Developer Center — giving you access to robust documentation no matter what your use case. There are now quickstart guides, tutorials, and product overviews available in the docs section. Whether you’re just getting started and want to search for a number and send your first SMS, or you’re working on more complex integrations like two factor authentication or introducing conferencing capabilities — you’ll be able to find a step-by-step guide with handy code snippets to help you get the job done.

We’d love your feedback

As you’re using our developer docs, let us know if they’re working for you by clicking YES or NO at the bottom of the page. Can’t find what you’re looking for? Stuck on a step? Our team of engineers and product managers are on slack 24/7 to help. Even if what you want doesn’t exist yet, we’ll work around the clock to try and come up with a solution.

Current voice or SMS provider holding you hostage?

If you’re currently using Twilio for programmable voice or SMS, you’re probably paying too much for subpar service. That’s why in addition to the new Telnyx API, SDKs and developer docs — we’ve also developed a set of tools to make switching from Twilio to Telnyx a breeze.

Twexit API

Our Twexit API means you can switch your programmable SMS API from Twilio to Telnyx with minimal changes to your existing code. And, by making a Twexit you could save up to 70% on your messaging costs.

TeXML Translator

TeXML Translator allows you to build applications with embedded voice using Telnyx numbers — fast. If you already have a TwiML application using programmable voice verbs, simply configure your Telnyx portal connection to point at your endpoint and when a call comes in, we’ll do the rest.

By using the Telnyx API for voice and messaging, you’ll unlock superior quality, lower rates, more control, and better support.

Using API v1?

If you’re an existing customer using version one of our API, don’t worry — you’ll continue to receive exactly the same level of support you do now. But, to reap the benefits of a faster and easier-to-use API, we do recommend switching to the new version when you’re ready.


To help make sure the switch is risk and hassle free, we’ve put together a couple of simple guides with everything you need to know for a smooth transition.
