Twilio Changelog

We have updated the characters that can be included in the credentials for webhook authentication. Starting today, characters will be limited to those that are included on this list. Please ensure your webhook credentials (username + password) adhere to this updated list to continue uninterrupted access to our webhook.

In order to keep you in carrier compliance and ensure fair service across all customers, we now have rate limits in place for MMS service. While you can still send messages to Twilio at a rapid rate, the delivery rate for each account is now capped at 25 messages per second (MPS) and for each Twilio long code at 1 MPS.

For time-sensitive messages, we recommend that you keep a close eye on the queue length via Message Queue Insights in the console. You can also find more details on this page.

Flex admins and supervisors can now monitor live messaging conversations while managing their agents. The Flex Teams View provides a real-time transcript for any of Flex's messaging channels, like SMS, WhatsApp, or Facebook Messenger.

Learn more about supervisor capabilities and Teams View programmability in our Monitoring Agent Activity guide.

Twilio Video Recordings, previously in Public Beta, is now Generally Available. Video Recordings allows you to flexibly record any of your Twilio Video Group Room interactions, with separate recording files for each audio and video track of all Room participants. Our API and pricing has not changed with the GA release.

As part of the GA release, we are introducing Video Recordings bulk deletion capabilities in the Twilio Console. This allows you to delete a large set of Video Recordings at once instead of deleting them one-by-one.

Twilio Video Compositions now supports Bulk Deletion in the Twilio Console. This capability provides customers a much simpler way to delete large sets of Video Compositions compared to the previous process of individual Video Composition deletions.

Flex now includes a pilot dialpad, enabling your contact center agents to make outbound calls to customers, add internal employees or external numbers to a call, and send DTMF tones to connected calls. Enable the feature under the Pre-Release Features section in the Flex Admin UI.

Learn more about the Dialpad and Pre-Release Features within our End User Guide.

Twilio's Programmable Voice platform for HTTP callbacks (webhooks) has been enhanced to allow you to easily override our default connection settings on a per request basis, giving you simple and flexible control of callbacks to your server/applications.

Twilio uses HTTP callbacks (webhooks) to let your application know when events happen, such as receiving an incoming phone call. When the event occurs, Twilio makes an HTTP request (usually a POST or a GET) to the URL you configured for the webhook. Twilio has implemented the override as a URL extension in the form of "fragments" that can be added to the standard HTTP webhook URL on a per request basis.

The Connection Override parameters allow you to specify:

• Longer timeouts to better support intermittent network issues between Twilio and your server/application.
• Shorter timeouts to speed up failover (to fallback URL) in the case of an outage on your server/application.
• HTTP callback connection retries on failures/timeouts.
• The egress Twilio Edge Location for your HTTP callback
• The total timeout limit for all of the retries to complete your request.
• The use of Server Name Indication (SNI), if your server/application requires SNI to ensure a proper TLS handshake for all attempts.

For details please refer to our user documentation.

Advanced Opt-Out gives customers granular control over the end-to-end compliance experience for their customers and users. Customers can now customize opt-in, opt-out, help keywords, and confirmation messages on a global basis with per-country or per-language overrides all within the console.

Outbound Programmable Fax is now Generally Available. Customers can build production applications to send faxes at scale using a simple and reliable REST API. Inbound Programmable Fax (receiving faxes) will remain a beta product. Learn more here.

Media reconnection states and events: With this API, auto reconnect is attempted if a network disruption occurs.

New Region:de1-ix is now available in the list of regions

New Error Object: Errors emitted through Device.on(‘error’) and Connection.on(‘error’) now contain a new twilioError parameter which provides more details about the error.
