OAuth for Twilio APIs is now in GA

Mon, 06 Apr 2026 14:30:00 -0400

Twilio Communications APIs now support OAuth 2.0. Upgrading to OAuth 2.0 makes your applications more secure than using traditional API keys or Auth tokens. Here is why:

Short-lived tokens: OAuth 2.0 generates short-lived access tokens instead of static, long-lasting credentials.
Scoped access: Each token only works with the specific APIs it was issued for, so a compromised token doesn't expose everything.

A2P 10DLC campaign registration will require privacy policy and terms & conditions URLs starting June 30, 2026

The error_code attribute will also be removed from each attempt. To obtain updates on message delivery status, new subscribers should now use the new Message Status Event Stream.

Verify Events: Verification Event Stream V3 released with new Tags parameter

Wed, 01 Apr 2026 19:00:00 -0400

Verify Event's Verification stream has a new version 3 that includes a new "tags" parameter in each attempt.

Voice Insights: Trust & Engagement Insights and Reports API (GA)

Tue, 31 Mar 2026 03:00:00 -0400

Voice Insights Trust & Engagement Insights and its companion Reports API are now Generally Available. This combined release provides a comprehensive solution for managing outbound calling health and campaign ROI.

Trust & Engagement Insights offers a specialized Twilio Console dashboard to detect behaviors triggering spam labeling, identify blocked calls, and optimize dialing windows with a best-time-to-call heatmap. Users can quantify campaign effectiveness through a visual engagement funnel and measure the ROI of trust investments like Branded Calls.

The Reports API serves as a zero-infrastructure companion, allowing you to programmatically retrieve these same aggregated metrics—per account or per phone number—with a single call. By outsourcing data processing to Twilio, you can accelerate decision-making and reduce operational costs by up to 90%.

Key Benefits:

Holistic Health: Monitor Trust & Engagement scores to proactively mitigate spam labeling and blocks.
Performance Optimization: Use heatmaps and human-answer rates to refine dialing strategies.
Programmatic Access: Use the Reports API to build custom dashboards or integrate metrics into your own internal tools.
ROI Attribution: Compare branded vs. unbranded call performance to justify trust product investments.

These features are available exclusively as part of Voice Insights Advanced Features.

Learn more in our Trust & Engagement Insights and the Reports API documentation.

Twilio SCIM API

Sun, 29 Mar 2026 19:00:00 -0400

Add a Flex Instance to existing Twilio account or subaccount

Thu, 26 Mar 2026 14:30:00 -0400

We are excited to announce that Flex instances can now be added to any existing Twilio account or subaccount. Key features include:

Reuse existing resources: You can now add Flex to any existing (non-Flex) Twilio account. This allows you to leverage existing phone numbers and Studio flows without the need for time-consuming resource migrations.
Subaccount support: Flex instances can now be deployed within Twilio subaccounts. This is ideal for managing distinct Flex environments for:
- Regional or departmental deployments: Separate instances for different countries or regions or departments like sales or support.
- SDLC environments: Clear separation between Dev, Staging and Production.
- Tenant isolation: ISVs can provide strict data and configuration isolation for end-customers within a multi-tenant architecture.

Detect entity context changes with data freshness for Linked Audiences in Segment

Thu, 26 Mar 2026 01:00:00 -0400

In Segment, Linked Audiences now supports data freshness detection for Identify events. When you configure an activation with the new "Profile enters or exits audience or entity values changed" trigger, Segment detects changes to entity context data between runs and emits an Identify event for affected profiles — even if their audience membership hasn't changed. This keeps enrichment values up to date in Braze, Customer.io, and AWS S3, making it easier to power time-sensitive journeys like past-due reminders, onboarding sequences, and abandoned cart campaigns.

To learn more, see our Linked Audiences docs.

Create entity-based Linked Audiences in Segment

Thu, 26 Mar 2026 01:00:00 -0400

In Segment, you can now choose to build entity-based Linked Audiences, explicitly scoped to entities such as accounts, businesses, or households. Once users select the activation target upfront, the builder dynamically adapts, ensuring conditions, operators, and validations match user expectations for that specific entity. When you preview your Linked Audience, you'll see the count of audience members who meet the criteria and a sample of matching entities.

To learn more, see our Linked Audiences docs.

Configure Part of Audience to import audience conditions in Segment

Thu, 26 Mar 2026 01:00:00 -0400

In Segment, when building an audience based on audience membership, you can use existing audiences as criteria for creating new audiences. You can include or exclude profiles based on their membership in other audiences, allowing you to generate more specific audience segments. You can configure your conditions with:

Import audience conditions: This copies the conditions from the referenced audience and generates a combined SQL query. The audience runs independently, even if you disable the original audience or update it later. Use this option when you need the freshest compute result, since this eliminates the Profile Sync delay (about 1 hour).
Use audience membership traits: This references the original audience membership traits, so it may take extra time to update if that audience needs to recompute. Use this option if the base audience membership doesn’t need to be recomputed every time, in order to save on compute costs.

To learn more, see our Linked Audiences docs.

RCS support now available in Studio

Wed, 25 Mar 2026 01:00:00 -0400

Twilio Studio now natively supports RCS (rich communication services) for both outbound and incoming message flows. This means you can now build and automate rich, branded, and interactive messaging experiences directly within Studio, leveraging all the benefits of RCS—such as rich media, card crousels, and webviews—without the need for workarounds or custom integrations.

For configuration details and best practices, see our documentation:

Start Conversation widget now available in Studio

Thu, 19 Mar 2026 01:00:00 -0400

Studio now includes the Start Conversation widget, which enables Studio flows to initiate a two-way Twilio Conversation without requiring custom code or direct API calls. This widget creates a Conversation with a single participant and configures Studio to continue the flow when inbound messages are received.

Note that this widget is only for outbound/REST API triggered flows. Inbound flows already support Twilio Conversations without the Start Conversation widget.

For more information, see our Start Conversation widget docs.

Increased MMS rate limits for A2P 10DLC Phone Numbers in the U.S. starting March 18, 2026

Tue, 17 Mar 2026 02:00:00 -0400

Starting March 18, 2026, MMS rate limits for Application-to-Person (A2P) U.S. 10-digit long code (10DLC) numbers are determined by Brand Trust Score and Campaign use case, replacing the previous fixed account-level cap of 1 message per second (MPS).

Twilio Now Supports Unified Opt-Outs across RCS, SMS, and MMS channels

Sun, 15 Mar 2026 14:30:00 -0400

Twilio Programmable Messaging automatically unifies opt-out management across RCS, SMS, and MMS channels.

When an end-user replies with any opt-out keywords (such as STOP, CANCEL, or UNSUBSCRIBE etc) to an RCS message, Twilio automatically enforces that opt-out for all future SMS or MMS messages sent from that same Sender or Messaging Service. Conversely, opt outs on SMS or MMS will automatically block future RCS messages.

Any attempt to message an opted-out user across these unified channels will now fail and return Error 21610.

This cross-channel compliance is active by default to protect your sender reputation, prevent accidental messaging on fallback channels, and requires no code changes to implement.

For more information, read our documentation.

For more information, see our ConversationRelay widget docs.

More actionable error codes for A2P 10DLC Campaign registrations

Fri, 06 Mar 2026 00:00:00 -0500

Starting March 23, 2026, we’ll begin rolling out more specific and detailed error codes for US A2P 10DLC Campaign registrations.

These new codes are designed to give you clearer, more actionable feedback when a campaign is rejected or requires an edit - helping you resolve compliance issues faster and get your messaging live.

The existing error codes will still be supported, but these new granular codes provide the specific context needed for rapid troubleshooting.

What’s changing?
Currently, A2P 10DLC rejection messages can sometimes be broad, making it difficult to identify the exact compliance blocker. With this update, you’ll see granular error codes that pinpoint the specific reason.

These new codes will appear in:

API Responses
Event Streams
Twilio Console (Campaign Details Page)

What this means for you
If you have built custom logic or processes to handle A2P 10DLC registration errors, we recommend reviewing your error mapping.

Updating your tools to reflect these new, specific codes will allow your end-customers and operations teams to respond to rejections with much higher precision.

For a full list of the new codes and their meanings, please refer to the Support Article on Campaign Rejections.
