Toll-Free MMS

We’re excited to announce that we will now be offering MMS for Toll Free Messaging in the US and Canada. Toll Free messaging allows for high throughputs similar to short code, but costs less and can be provisioned in minutes. With this feature, customers can:

• Search and purchase MMS enabled Toll Free numbers in the Mission Control Portal
• Send and receive MMS on your Telnyx number

To get started, log into your Telnyx account, where you can search for and purchase an MMS enabled Toll Free number.

Twexit API Released

Telnyx is pleased to announce our Twexit API. This will allow users to switch their messaging services from Twilio by making minimal changes to their existing Twilio messaging code.

Follow the steps to make the switch:

1: Telnyx Portal Setup

Start by creating a new messaging profile account on your Telnyx Portal, and set the API version to “Twexit API”. Then assign an SMS-capable number to that messaging profile.

2: Send A Message

To begin sending messages, simply change the following fields in your code:

1. Update the host and AccountSid in references to the Twilio messages endpoint.
2. Twilio: POST https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Messages.json
3. Telnyx: POST https://api.telnyx.com/2010-04-01/Accounts/{organization_id}/Messages.json
4. Update Authentication Header:
5. Twilio: Authorization: Basic base64({AccountSid}:{AuthToken})
6. Telnyx: Authorization: Basic base64({organization_id}:{auth_v2_api_key})
8. Update the From number in the request payload.

Telnyx Inbound Message notifications will be in the same format as those sent by Twilio and will be sent to the inbound webhook URL set on the messaging profile.

For a full list of parameters and more API features, go to the Twexit API Developers Docs.

URL Shortener Released

Custom Shortlinks With Telnyx

Today, many customers utilize public URLs in their SMS and MMS messages. And these Common URL shorteners are increasingly being blocked or flagged as SPAM. By using a Telnyx custom URL, you can more quickly update your public URL, helping ensure that your messages get through the first time, every time.

You’ll be able to define custom URLs to communicate your use case and add your own brand name to the domain, making your links instantly recognizable to customers. And when a recipient trusts your link, they’re far more likely to click.

Custom URL Shortening is enabled per Messaging Profile. If you send SMS via phone numbers under this profile, and they contain any URLs that are part of the list of supported URLs, then they will be replaced with links that the URL Shortener service generates.

Please reach out to customer support so that they can work internally to create your customer URL shortener. Please provide the following information so customer support can process your request:

1. Your customer ID
2. Your custom domains (or let us know if you need us to provide the domains for you)
3. The profile IDs that you need the link shortner assigned to Please note that any domains that you provide need to be set up with AAA records.
