To improve message reliability and security, we are updating the Toll-Free Verification process to require business registration numbers.

These fields are available now in Console and API.

We're transitioning TLS certificate management for Twilio's classic HTTP REST APIs from manually managed DigiCert certificates to AWS Certificate Manager (ACM). This change prepares Twilio for industry-wide changes that will reduce maximum certificate lifespans to 47 days by 2029.

Starting April 28, 2026, we’re deprecating these region-specific API domain patterns: 

• api.ie1.twilio.com

• api.au1.twilio.com

• api.br1.twilio.com

• api.de1.twilio.com

• api.jp1.twilio.com

• api.sg1.twilio.com

• api.us2.twilio.com

The Event Types will be restricted after 30 January 2026 at 22:00 UTC. Learn more about using restricted Event Types in Restricted Event Types. If you delete any of your existing subscriptions or remove one of the restricted Event Types, you will not be able to create a new subscription or add the restricted Event Types back.

Twilio Expands Branded Calling Globally!

Starting September 24, 2026, we're requiring HTTPS for all traffic to Functions and Assets, which means customers need to update any webhook or callback subscriptions for these URLs to use https:// instead of http://. After September 24, 2026, any HTTP requests will receive a 301 redirect response and disrupt customers’ Functions. 

Starting January 31, 2026, any new function customers create will default to Node.js v22. Existing functions will keep running on Node.js v18, and they'll only move to v22 when customers choose to redeploy them. 

We fixed an issue where newly created subaccounts didn’t inherit Voice Insights Advanced Features even though it was enabled on the parent account. If you created subaccounts between September 1, 2025 and January 9, 2026 and relied on automatic inheritance of Advanced Features, you can enable those subaccounts in the Subaccounts tab of Voice Insights Settings or via the Voice Insights Settings API.
