A common need in video calling applications is to allow a user to play a media file for the other participants in the call. This can enable, for example, a teacher or doctor to share a recording with the call attendees.
The MediaStream API
But the MediaStream APIs cover much more than webcams and microphones and can be used to obtain
MediaStream objects from other sources. For example, the …

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”).
To build this solution, you will …
Eurovision is near and while you can't officially vote just yet, we thought we'd allow the public to vote already - and not just for this year but for ALL Eurovision's that have happened since the beginning of Eurovision. That includes 2020 - the year Eurovision was cancelled.
How do I vote?
Text '2022' to one of the following numbers to get the list of all the 2022 participants and their youtube videos. Once you have picked a winner, text “2022 Country” to the same number (e.g. 2022 Germany).
What about the other years... Could we maybe vote for those too?
You can text any year from 1956 to 2022 to any of the above numbers and then vote for your favourite song.
How do I see the results?
You can see the …
State variables are one of the most important building blocks in front end applications developed with the React library. When a state variable is updated, React automatically re-renders any application components that depend on it, ensuring that the application always displays updated information to the user.
The automatic state update mechanisms in React are fantastic, but they are limited to a single instance of the application. Sometimes, however, an application needs state variables that are automatically synchronized across all running instances of the application. In this tutorial you are going to learn how to create a custom React hook that implements synchronized state variables using Twilio Sync as a cloud storage back end.
To work on this tutorial you will need the following items:
- A Twilio account. If you are new to Twilio click here to create a free account now and receive $10 credit when you upgrade to …
When sending emails with Twilio SendGrid, sometimes you want to be able to keep track of the status of these emails, such as when a recipient opens the message or reports it as spam. This is made possible by the use of Event Webhooks. Let's walk through how to use Node.js and Express to track the status of emails that you send.
Prerequisites and dependencies
Make sure you have the following before moving on:
- Node.js and npm installed (do this first if you haven't already)
- A free SendGrid account
- An email address to test out this project
- A domain on which you will receive emails. For the purposes of this article, I’m going to use yourdomainhere.com. You will need to replace it with your own domain name.
Many organisations in the banking sector are still using RSA SecurID with hardware tokens for multi factor authentication (MFA). However, employees might forget their hardware token thus won’t be able to login. This leads to high support costs, poor user experience and reduced productivity. This is the exact challenge that one of our customers in banking is trying to address. So we worked together to explore how Twilio Verify Service can be leveraged as an alternative MFA. This will allow their employees to login their protected systems by using a One-Time Password (OTP) delivered to their employee’s mobile phone.
This blog post will walk you through the steps of how to integrate Twilio Verify service with RSA SecurID.
The RSA Authentication manager requires that you pin a certificate for the HTTPS endpoint of your SMS provider. This will cause your application to break when the certificates change in the future. …
Displaying your email address on a website can result in your email being scraped and used for spam. One way to get around this, but still allow people to contact you from your website, is to build a contact form.
In this post you will build a contact form using SendGrid to deliver emails to your inbox without exposing your email address.
You will build the project with Twilio Functions, but you could adapt the code to use in any Node.js environment.
How is this different to sending an email with an API?
When someone fills in a contact form, you might expect to receive an email in your inbox from their email address. However, to maintain a good email sending reputation, SendGrid only allows you to send emails from addresses that you have verified individually or from domains you have authenticated.
So, instead of using the submitted …
