Twilio — API, Marketing product updates and releases, tracked on megachangelog.
SendGrid now offers automatic SSL certificate provisioning for branded links, eliminating the need for external certificate management. A new auto_ssl parameter in the Link Branding API enables this feature, with certificates provisioned and hosted by SendGrid alongside traditional link branding DNS records.
Twilio Verify is automatically updating the default geo permissions for Italy and Argentina from "Allow all traffic" to "Monitor all traffic for fraud" effective August 19, 2026, to combat a rise in SMS Pumping fraud. This change only applies to existing accounts still using the default setting; accounts with custom configurations remain unaffected.
Customers can now send WhatsApp Content Templates to many recipients at once with personalization using the Bulk Messaging API, and configure fallback strategies like WhatsApp to SMS and RCS to WhatsApp for improved campaign delivery.
Twilio is retiring Functions Classic and automatically migrating all accounts to the new Functions platform. Starting September 13, 2026, new Functions (Classic) cannot be created, and between September 14 and October 26, 2026, all existing Functions, assets, URLs, environment variables, and code will be automatically migrated with no action required from customers.
The Consent Management API now allows programmatic re-opt-in of users on US and Canada Toll-Free numbers, enabling consent to be logged outside of messaging channels and automatically passed to downstream networks to clear opt-out blocks and resume messaging.
Twilio will rotate the end-user TLS certificate for all REST API endpoints on September 9, 2026. Only the end-user certificate will be renewed while root and intermediate certificates remain unchanged. Most customers won't be affected unless they manually pin certificates.
Dedicated IPs are now available for Twilio Email with built-in warm-up scheduling and IP pool segmentation, enabling better control over sending reputation and email deliverability at scale.
Twilio is adding new error codes to provide clearer feedback when Toll-Free Verification and A2P 10DLC campaign registrations are rejected, helping developers understand and resolve issues more quickly.
The Twilio Voice JavaScript SDK now includes production-ready reference components for noise cancellation, supporting both open-source RNNoise and commercially-licensed Krisp options.
Twilio is introducing a new dedicated regional IP address (3.80.20.0/25) for Event Streams webhook traffic in US East on September 15, 2026. Customers who validate webhook traffic by source IP should add this range to their allowlist; the legacy shared range will remain active alongside it temporarily.
Twilio SendGrid removed the Send to Coworker action from Domain Authentication setup due to low usage and security concerns. Users should now share DNS configuration details directly through internal communication channels like Slack or ticketing systems instead of email.
Conversations (classic) now supports WhatsApp Card and WhatsApp Flow content types, enabling you to send rich templated messages with interactive buttons and multi-step flows directly through the Conversations API, previously only available via Programmable Messaging.
Restricted API Keys now support resource-level permissions for Conversations (classic), enabling fine-grained control over operations like listing conversations, sending messages, and managing participants. This reduces security risk by limiting key scope to only necessary operations.
US Enhanced Branded Calling is now generally available for all customers, allowing them to display branded elements like logos and call reasons to increase trust and recognition when reaching customers on T-Mobile and Verizon networks.
On September 1, 2026, date_created and date_updated fields in Functions and Assets resources will be corrected to return accurate UTC timestamps instead of values shifted forward by 7 hours. The fix applies retroactively to all resources, and customers using these fields for sorting, filtering, or comparisons should review their implementations before the correction date.
Twilio Event Streams now supports real-time notifications for WhatsApp message template status and category updates, allowing you to subscribe to template lifecycle events and automatically trigger workflows when Meta approves, rejects, or recategorizes templates instead of relying on periodic polling.
Error code 30915 now applies consistently across both A2P 10DLC campaign registration and Toll-Free Verification to flag Sole Proprietor registrations that are actually registered legal entities like LLCs or corporations. The error is triggered by corporate identifiers in business names, website information, or business registration documents that indicate a registered entity rather than a sole proprietorship.
Lookup Line Status package is now in public beta, allowing you to check mobile phone number status (active, inactive, unreachable, reachable, or unknown). Use this to validate phone numbers in your contact database and improve campaign efficiency.
The RCS error code returned for undeliverable messages to unreachable devices will change from 30036 to 30046 on August 10, 2026. Error code 30046 more accurately indicates device-side conditions like offline status or no connectivity, helping developers troubleshoot failures more effectively.
The rollout of changes to the Conference list endpoint that limits results to in-progress conferences is being delayed until September 30, 2026 based on customer feedback.
Twilio Functions now supports Node.js v24 as a build runtime, selectable via the Console or Serverless Toolkit configuration. The upgrade requires @twilio/runtime-handler version 2.1.2 or later, with automatic upgrades available for compatible services during deployment.

Branded Calling is now available in Public Beta for customers in Canada, Germany, and the United Kingdom, expanding the service beyond the US market.
Email notifications are now available for A2P 10DLC campaign registrations, providing visibility into the onboarding pipeline with automated updates at four critical lifecycle stages: initial registration, approval, rejection, and resubmission. Notifications route to your Brand registration email or A2P bundle email address, with special handling for ISV subaccounts.
Organization APIs now support OAuth 2.0 client credentials authentication, enabling programmatic user and role management via new SCIM and Role Assignments APIs, with Microsoft Entra ID SCIM integration support.
Twilio will update SIP signaling IP addresses for Programmable Voice SIP and Elastic SIP Trunking over Interconnect in H2 2027, moving to the 159.26.160.0/20 range. Customers using these products must update their network firewalls to allowlist the new IPs before the cutover date.
The conference_participant field is being removed from Voice Insights Call Summary in the REST API and Event Streams on August 1, 2026. Users should migrate to the Conference Insights API or Conference Insights Event Streams for conference data.
Twilio improved RCS delivery optimization and fallback behavior so that message status updates no longer depend on queueing time, preventing premature SMS fallbacks while balancing timely message resolution. The delivery confirmation timeout has been adjusted, and users can control fallback timing via the ValidityPeriod parameter.
