Twilio Changelog

It is now possible to track the status of each message in a Conversation with the Delivery Receipts feature for the Conversations API.

The same statuses you rely on for your messaging functionality are now supported for the Conversations API, offering instant status updates like "sent" or "delivered" via REST API. These Receipts show detailed information on each message in a conversation, including the "read" status for WhatsApp.

Aggregated statuses are visible directly in the REST API Messages resource and you are able to see individual receipts by setting up a dedicated webhook or through the Receipts API resource. Direct SDK exposure is also to follow soon.

Check documentation and use-cases for more information!

Twilio Voice Client Mobile SDK for Android and iOS now have the CallerInfo object and TVOCallerInfo class to represent information about the caller. It can be used to display a trust indicator to the recipient when an incoming call, from the public telephone network, has been verified under the SHAKEN/STIR framework.

A verified call that has been given the highest attestation under SHAKEN/STIR means that the carrier that originated the call both (1) knows the identity of the caller, and (2) knows the caller has the right to use the phone number as the caller ID.

When your application receives a request webhook that has the new StirStatus parameter, all you have to do is <Dial><Client> and Twilio will implicitly pass the StirStatus to the Mobile Client.

Twilio SendGrid now provides two security features that allow you to verify that email event data is being posted by Twilio SendGrid: a Signed Event Webhook and OAuth 2.0. These security features are independent of one another and can be used together.

Twilio SendGrid’s Signed Event Webhook uses the Elliptic Curve Digital Signature Algorithm to sign requests. The signature allows customers to verify that event data is being posted by Twilio SendGrid.

OAuth 2.0 for the Twilio SendGrid Event Webhook allows customers to verify that Twilio SendGrid is properly authorized by them to post to their URLs using the Client Credentials grant type.

We have updated all Flex projects that use Automatic Updates to Flex UI 1.20.

This release of Flex UI introduces image and file sharing for chat channels in Flex. Agents and webchat users can now share images, documents, and other files during a chat conversation. This is currently available as a Pilot feature. You can learn more about this feature and how to enable it within our documentation.

Other notable features include:

• Notification to signal connectivity issues: Users will now be notified if Flex UI has lost network connectivity and is trying to reconnect.
• Initialization error page: If Flex UI encounters an error during initialization, users will now see details of the error and they can download a report which will provide technical details for troubleshooting.
• FlexError class: Developers can use a new API to unify the experience when working with Flex exceptions.

Reminder: You can pin to individual versions of the Flex UI or manage your Automatic Updates within the Flex Admin UI.

This release includes support for the expansion of Twilio’s Global Infrastructure via Edge Locations which allows connectivity control into and out of Twilio’s platform. These changes will provide an improved experience bringing Twilio’s public and private connectivity closer to your application.

Note: All these changes are backward compatible and will not impact existing configurations.

Programmable Messaging supports Edge Locations for connections to Twilio’s infrastructure via the Base URL in Twilio's API api.{edge}.us1.twilio.com.

Twilio is open sourcing a Voice Notification App built in ReactJS for the Web. This reference app can be deployed to Heroku in minutes and demonstrates how to leverage Programmable Voice and Twilio SDKs to create a voice notification system to make calls to your customers to deliver time-sensitive messages. Whether you are building a voice notifications solution for Emergency Alerts, Appointment Reminders or Sales & Marketing use cases, this reference app can be used as a starting point.

Access to the source code will help customers understand how to use Twilio “building blocks” and Programmable Voice APIs to build an application for their own notification use case and accelerate development.

For additional information on getting started see the source code repo here.

.We are excited to announce the General Availability of Messaging Insights for all customers in console. Messaging Insights offers unprecedented transparency for customers to monitor, troubleshoot, and optimize message deliverability and engagement on Twilio.

The GA launch enables multidimensional filters, a Message List view and the following four reports.

1. Overview: high-level view of your outgoing and incoming messages
2. Delivery & Errors: deep dive into factors that affect deliverability to help you identify what is causing an issue
3. Responses: visualize and filter the inbound messages that you’re receiving back from your end users
4. OTP Conversion: aggregate and visualizes the information that you have sent to Twilio about successful OTP messages

Messaging Insights is available on the Twilio console for all customers. To learn more see the Messaging Insights docs.

The Programmable Voice Conference REST API and <Conference> TwiML now supports adding custom labels when creating and adding participants into a conference. Prior to this change, developers were required to use Participant’s Call Sid to read or update specific participants in a conference. Developers can now provide a label to a participant at the time of adding them into the conference. The label can then be used to read, update or delete participants. The custom participant label means developers no longer have to use Twilio identifiers, and instead use participant labels that make sense for your specific use case.

For example, if you have access to the Participant’s CallSid, this code snippet shows how to mute a participant using the CallSid. Alternatively, this code snippet demonstrates how to mute a participant that was given the label of Customer at the time of being added into the conference.
