ElevenAgents matured its workflow and configuration infrastructure, moving from basic agent capabilities toward fine-grained control systems for multi-agent deployments. The platform shipped version control for agents—full branching, merging, and deployment endpoints—alongside workspace-level configuration management through environment variables and auth connections that agents reference at runtime. Simultaneously, the team tightened execution control: MCP tools can now be scoped per workflow node, guardrails gained configurable execution modes and trigger actions, and conversation analysis became scopable to individual agents in multi-agent workflows. The product also expanded integration surface area with SIP header exposure as dynamic variables, file upload support in conversations, and oauth/advanced auth for MCP servers, while UI refinements like widget dismissibility and agent status indicators made deployment more flexible for end users.
Environment variable support and guardrail automation expanded the platform's configuration depth. Schemas now model environment variable references in MCP server configs, trigger actions for conditional call handling, and auth connection management. The Agents Users page reached general availability with unified conversation history, while custom SIP X-headers became directly accessible as dynamic variables in call flows.

### ElevenAgents
-
**Conversation topic discovery**: A new [conversation topics](/docs/api-reference/conversations/get) endpoint (`GET /v1/convai/agents/{agent_id}/topics`) returns the latest topic discovery results for a given agent, surfacing recurring themes across conversations. The [list conversations](/docs/api-reference/conversations/list) endpoint now accepts a `topic_ids` query parameter to filter conversations by discovered topic.
-
**Knowledge base content search**: A new [search knowledge base](/docs/api-reference/knowledge-base/search) endpoint (`GET /v1/convai/knowledge-base/search`) provides fuzzy text search over knowledge base document content. Results include highlighted snippets with `SearchHighlightSegment` objects and support cursor-based pagination with configurable page sizes (up to 100, default 30). Filter by document type with the optional `types` parameter.
-
**Flexible branch merging**: The [merge branch](/docs/api-reference/agents/branches/merge) endpoint no longer restricts merges to the main branch -- any branch can now be used as a merge target. A new optional `force` boolean parameter overrides timestamp-based conflict resolution when set to `true`. Branch metadata responses now include `parent_branch_id` and `merged_from_version_id` for better lineage tracking.
-
**Secret dependency management**: A new [get secret dependencies](/docs/api-reference/workspace/secrets/get-dependencies) endpoint (`GET /v1/convai/secrets/{secret_id}/dependencies/{resource_type}`) returns paginated dependency lookups filtered by resource type (`tools`, `agents`, or `phone_numbers`). The [list secrets](/docs/api-reference/workspace/secrets/list) endpoint now accepts a `dependency_limit` query parameter to control how many dependencies are previewed per secret, with `agents_has_more`, `tools_has_more`, and `phone_numbers_has_more` flags indicating when additional dependents exist beyond the preview.
-
**New LLM options**: Added `gemini-3.1-pro-preview`, `qwen35-35b-a3b`, and `qwen35-397b-a17b` to the list of available LLM providers for agent configuration.
### Voices
- **Non-community voice filter**: The `voice_type` query parameter on the [list voices](/docs/api-reference/voices/search) endpoint now accepts `non-community`, which returns `personal` and `workspace` voices combined while excluding library copies. This provides a convenient filter for teams that want to see only their own voices without community-shared ones.
### SDK Releases
#### Python SDK
- [v2.43.0](https://github.com/elevenlabs/elevenlabs-python/releases/tag/v2.43.0) - Fern regeneration for the April 13, 2026 API schema, including knowledge base content search, conversation topics, flexible branch merging, and new LLM providers.
#### JavaScript SDK
- [v2.43.0](https://github.com/elevenlabs/elevenlabs-js/releases/tag/v2.43.0) - Fern regeneration for the April 13, 2026 API schema, including knowledge base content search, conversation topics, flexible branch merging, and new LLM providers.
#### Swift SDK
- [v3.1.3](https://github.com/elevenlabs/ElevenLabsSwift/releases/tag/v3.1.3) - Reduced background noise detection in software muted VAD, preventing false voice activity triggers when the microphone is muted.
#### Packages
-
[@elevenlabs/client@1.2.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/client@1.2.0) - Fixed `getInputVolume()` and `getOutputVolume()` returning 0 in React Native by adding native volume providers using LiveKit's RMS and multiband FFT processors. `getInputByteFrequencyData()` and `getOutputByteFrequencyData()` now return data focused on the human voice range (100-8000 Hz), which is more useful for voice visualization, and on web `getInputVolume()` and `getOutputVolume()` are also computed from this range.
-
[@elevenlabs/react@1.1.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react@1.1.0) - Fixed `startSession` errors being swallowed instead of surfaced via `onError` in `ConversationProvider`. Previously, when `Conversation.startSession()` rejected (e.g., "agent not found"), the UI would get stuck in "connecting" with no error feedback.
-
[@elevenlabs/react-native@1.1.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react-native@1.1.0) - Updated to `@elevenlabs/client@1.2.0` and `@elevenlabs/react@1.1.0` with native volume provider fixes.
-
[@elevenlabs/convai-widget-core@0.11.3](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/convai-widget-core@0.11.3) - Fixed transcript message ordering in voice mode where agent responses could appear before user messages.
### API
## April 7, 2026
ElevenAgents
Scoped conversation analysis: Evaluation criteria and data collection items can now be scoped to conversation (full transcript) or agent (only the portion where a specific agent was active). Added scope field to PromptEvaluationCriteria, data_collection_scopes to [agent platform settings](/docs/eleven-agents/customization/agent-analysis), and a new scoped array of ScopedAnalysisResult on the [conversation analysis](/docs/api-reference/conversations/analysis/run-analysis) response. This is particularly useful for multi-agent workflows where each agent should be evaluated independently.Agent test folder management: Tests can now be organized into folders. New endpoints for [creating](/docs/api-reference/tests/test-folders/create), [retrieving](/docs/api-reference/tests/test-folders/get), [updating](/docs/api-reference/tests/test-folders/update), and [deleting](/docs/api-reference/tests/test-folders/delete) test folders, plus [bulk moving](/docs/api-reference/tests/test-folders/move) tests between folders.Tool and knowledge base overrides in workflows: Agent workflow node overrides now support tool_ids and knowledge_base fields in PromptAgentAPIModelOverrideConfig, allowing workflow nodes to control which tools and knowledge base documents each sub-agent can access.Response filter hide_all mode: Added hide_all option to ResponseFilterMode, forcing the system to hide all fields of a tool response from the agent.Visited agents in conversation history: The [get conversation](/docs/api-reference/conversations/get) response now includes a visited_agents array of VisitedAgentRef objects (with agent_id and branch_id), tracking which agents participated in a multi-agent conversation.Multimodal message support in hooks: The useConversationControls hook now exposes sendMultimodalMessage, and the MultimodalMessageInput type is exported from @elevenlabs/client, making it easier to send images and other multimodal content during conversations.
Speech to Text
Audio duration in responses: The [convert speech to text](/docs/api-reference/speech-to-text/convert) response now includes an audio_duration_secs field, providing the total duration of the transcribed audio without requiring client-side calculation.
Voices
Recording quality and review status: The [get voice](/docs/api-reference/voices/get) response now includes recording_quality (enum: studio, good, ok, poor, bad) and labelling_status (enum: in_review, review_complete) fields, providing visibility into voice quality assessment.

API
## April 1, 2026
ElevenAgents
MCP tool scoping in agent workflows: Agent workflow nodes can now restrict which MCP tools a sub-agent is permitted to call. When tool inheritance is disabled on a node, only the explicitly selected MCP tools are loaded for that sub-agent, giving teams precise control over tool access per workflow step.Conversation file uploads: The [create agent](/docs/api-reference/agents/create) and [update agent](/docs/api-reference/agents/update) endpoints now support a file_input field on ConversationConfig. When enabled, end users can attach images or PDFs in chat (requires an LLM with multimodal input support). Configurable with enabled (boolean) and max_files_per_conversation (integer).Re-run conversation analysis: New [run conversation analysis](/docs/api-reference/conversations/analysis/run-analysis) endpoint (POST /v1/convai/conversations/{conversation_id}/analysis/run) re-evaluates a completed conversation using the agent's current evaluation criteria and data collection settings, without needing a new call.Tool response mocking for tests: Agent simulation tests and test suite invocations now support a tool_mock_config field to control how tool calls are handled during testing. Use MockingStrategy (all, selected, none) to choose which tools are mocked and MockNoMatchBehavior (call_real_tool, raise_error) to set the fallback when no mock matches.Text search sort order: The [text search conversations](/docs/api-reference/conversations/messages/text-search) endpoint now accepts a sort_by query parameter with values search_score (default) or created_at, allowing you to control whether results are ordered by relevance or recency.mTLS auth connections: Agent auth connections now support mutual TLS (mtls) as an auth_type, in addition to the existing options. New CreateMTLSAuthRequest and MTLSAuthResponse schemas are available for creating and retrieving mTLS-authenticated connections.Max duration message: Added max_conversation_duration_message field to agent configuration. When set to a non-empty string, the agent will send this message to the user when the maximum conversation duration is reached.Branch and environment in conversation initiation: Added branch_id and environment optional fields to the conversation initiation client data (ConversationInitiationClientDataRequest) and [submit batch call](/docs/api-reference/batch-calling/create) request body, enabling routing to specific agent branches and environments.
Music
Video to music: New POST /v1/music/video-to-music endpoint generates background music from one or more video files. Videos are combined in sequence. Accepts optional description (up to 1,000 characters) and tags (up to 10 style tags such as upbeat or cinematic) to influence the generated track.
Speech to Text
Transcribe from URL: The [convert speech to text](/docs/api-reference/speech-to-text/convert) endpoint now accepts a source_url parameter (string, optional) for transcribing audio or video from a hosted URL, including YouTube videos, TikTok videos, and other video hosting services. This can be used as an alternative to uploading a file directly.
Voices
Total count in shared voices list: The [list shared voices](/docs/api-reference/voices/voice-library/get-shared) response now includes a total_count field, making it easier to implement pagination and display result counts.

Packages
This release includes the new v1.0.0 of the client side Agent SDKs. It features major breaking changes to @elevenlabs/client, @elevenlabs/react, and @elevenlabs/react-native. Review the migration guidance below before upgrading.
To help upgrade, we released a Skill to help your agents upgrade for you. Install it with
npx skills add elevenlabs/packages
You can read more about the v1 release and its improvements on our [developer blog](https://elevenlabs.io/blog/elevenagents-react-sdk-v1-0).
[@elevenlabs/client@1.0.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/client@1.0.0) — Breaking changes:Input and Output classes are no longer exported. Use the InputController and OutputController interfaces from @elevenlabs/client instead.Conversation is no longer a class — it is now a namespace object and a type alias for TextConversation | VoiceConversation. Remove any instanceof Conversation checks and subclasses.The default connectionType is now inferred from the conversation mode: voice conversations use "webrtc" by default, and text-only conversations use "websocket". To keep the previous behavior for voice, pass connectionType: "websocket" explicitly.VoiceConversation.wakeLock is now private. Pass useWakeLock: false in session options to suppress wake lock management.changeInputDevice() and changeOutputDevice() now return Promise instead of Promise or Promise.Replace conversation.input.analyser.getByteFrequencyData(data) with conversation.getInputByteFrequencyData().Replace conversation.input.setMuted(v) with conversation.setMicMuted(v).Replace conversation.output.gain.gain.value = v with conversation.setVolume({ volume: v }).getInputVolume(), getOutputVolume(), getInputByteFrequencyData(), and getOutputByteFrequencyData() now return 0 or an empty Uint8Array instead of throwing when no conversation is active.[@elevenlabs/react@1.0.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react@1.0.0) — Breaking changes:useConversation now requires a ConversationProvider ancestor. Wrap your component tree in and move options to the provider or to the hook.DeviceFormatConfig and DeviceInputConfig exports are removed. Use FormatConfig and InputDeviceConfig from @elevenlabs/client instead.New granular hooks replace the monolithic useConversation for better render performance: useConversationControls(), useConversationStatus(), useConversationInput(), useConversationMode(), useConversationFeedback(), and useRawConversation(). Each hook subscribes only to the state it needs, preventing unnecessary re-renders.New useConversationClientTool(name, handler) hook for registering client tools that agents can invoke, with automatic cleanup on unmount.Added controlled mute support via isMuted and onMutedChange props on ConversationProvider.[@elevenlabs/react-native@1.0.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react-native@1.0.0) — Breaking changes:The previous ElevenLabsProvider and useConversation API have been removed and replaced with re-exports from @elevenlabs/react. Replace ElevenLabsProvider with ConversationProvider and useConversation with the granular hooks (useConversationControls, useConversationStatus, etc.).On React Native, the package now polyfills WebRTC globals, configures the native AudioSession, and registers a platform-specific voice session strategy on import.[@elevenlabs/types@0.8.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/types@0.8.0) - Exports the CALLBACK_KEYS runtime array containing all keys from the Callbacks interface, used internally by the React SDK for callback composition.[@elevenlabs/client@0.16.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/client@0.16.0) - Added the guardrail_triggered server-to-client WebSocket event and the onGuardrailTriggered callback, which fires when the server detects a guardrail violation during a conversation. Also added type discriminants to TextConversation and VoiceConversation to enable discriminated union narrowing, and added startSession overloads that narrow the return type based on the textOnly option.[@elevenlabs/react-native@0.6.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react-native@0.6.0) - Added the guardrail_triggered WebSocket event and onGuardrailTriggered callback, consistent with @elevenlabs/client@0.16.0.[@elevenlabs/client@1.1.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/client@1.1.0) - Added client-side support for mocking tool responses in agent conversations, enabling test scenarios that simulate tool call outcomes without invoking real tools.[@elevenlabs/types@0.9.0](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/types@0.9.0) - Added type definitions for tool response mocking in agent conversations.[@elevenlabs/react@1.0.1](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react@1.0.1) - Updated to depend on @elevenlabs/client@1.1.0.[@elevenlabs/react-native@1.0.1](https://github.com/elevenlabs/packages/releases/tag/@elevenlabs/react-native@1.0.1) - Updated to depend on @elevenlabs/client@1.1.0 and @elevenlabs/react@1.0.1.

## March 23, 2026
ElevenAgents
Environment Variables API: New [environment variables](/docs/eleven-agents/integrate/environment-variables) endpoints for managing workspace-level configuration that agents can reference at runtime via {{system_env__}} templating. Supports string, secret, and auth-connection variable types with per-environment value overrides. Endpoints include [create](/docs/api-reference/environment-variables/create), [list](/docs/api-reference/environment-variables/list), [get](/docs/api-reference/environment-variables/get), and [update](/docs/api-reference/environment-variables/update).Auth Connections management: New workspace-level auth connections API for managing authentication credentials used by agent tools and integrations. Supports multiple auth methods including OAuth2 client credentials, JWT, basic auth, bearer tokens, custom headers, and integration-managed OAuth2 authorization code flows. Endpoints include create, list, and delete operations.Knowledge Base URL refresh: New [refresh](/docs/api-reference/knowledge-base/refresh) endpoint (POST /v1/convai/knowledge-base/{documentation_id}/refresh) to re-fetch and update content for URL-sourced knowledge base documents. Knowledge base documents also now support auto-sync configuration with enable_auto_sync, auto_remove, and auto_sync_info fields.Guardrail retry with feedback: Custom and content guardrails now support configurable [trigger actions](/docs/eleven-agents/best-practices/guardrails) with EndCallTriggerAction and RetryTriggerAction options. When set to retry, the agent re-generates its response with injected system feedback up to 3 attempts. Available placeholders include {{trigger_reason}} and {{agent_message}} for contextual retry guidance.Conversation History system variable: Added a new system__conversation_history dynamic variable that provides a lazily-evaluated, JSON-serialized conversation history at runtime. This is useful for passing full conversation context to tools, webhooks, or sub-agent handoffs.Webhook tool content type: Server tools now support a configurable [content type](/docs/eleven-agents/customization/tools/server-tools) for webhook body parameters, allowing you to choose between application/json and application/x-www-form-urlencoded formats. The URL-encoded format is useful for integrating with legacy systems, OAuth token endpoints, and payment processors.WhatsApp outbound messages: Updated the WhatsApp integration with a new [outbound message dialog](/docs/eleven-agents/guides/whatsapp) in the dashboard, enabling agents to send outbound messages in addition to calls through the WhatsApp channel.Agent and resource listing filters: The [list agents](/docs/api-reference/agents/list), [list knowledge base documents](/docs/api-reference/knowledge-base/list), and [list tools](/docs/api-reference/tools/list) endpoints now support a created_by_user_id query parameter (use @me for the current user).

API
## March 16, 2026
ElevenAgents
Users page is now generally available: The [list users](/docs/api-reference/users/list) page, which groups conversations by a user identifier, is now available to all workspaces. This allows you to view all users who have interacted with your agents, their conversation history, and contact details in a unified view.SIP inbound headers as dynamic variables: Custom SIP X- headers from inbound SIP trunking calls are now automatically exposed as dynamic variables in ElevenAgents conversations. Any custom SIP header (e.g., X-Contact-ID, X-Campaign-ID) passed by the caller is available in the agent prompt using {{sip_contact_id}}, {{sip_campaign_id}}, etc. These variables are also visible in the conversation history under the Phone Call tab. Reserved headers such as X-Call-ID and X-Caller-ID continue to map to system__call_sid and system__caller_id and are not overridden.Conversation filtering by tool outcome: The [list conversations](/docs/api-reference/conversations/list) and [text search conversations](/docs/api-reference/conversations/messages/text-search) endpoints now accept tool_names_successful and tool_names_errored query parameters (array of strings) to filter conversations by which tools succeeded or returned errors during the call.User listing improvements: The [list users](/docs/api-reference/users/list) endpoint now supports a sort_by query parameter accepting last_contact_unix_secs (default) or conversation_count, and a branch_id query parameter to filter users by agent branch.Force delete tools: The [delete tool](/docs/api-reference/tools/delete) endpoint now accepts a force query parameter (boolean, default false). When set to true, the tool is deleted even if it is used by agents, and it is automatically removed from all dependent agents and branches.Conversation embedding retention: The [ElevenAgents settings](/docs/api-reference/workspace/get) response now includes conversation_embedding_retention_days, which controls how long conversation embeddings are retained (maximum 365 days). A null value uses the system default of 30 days.Content threshold guardrail: Added the ContentThresholdGuardrail schema, which provides a configurable threshold-based guardrail with an is_enabled flag and a threshold value for content moderation.
Workspaces
Get all workspace groups: New [GET /v1/workspace/groups](/docs/api-reference/workspace/groups/list) endpoint returns all groups in the workspace, including each group's name, ID, members, permissions, usage limit, and character count.Seat type in bulk workspace invites: The [invite multiple users](/docs/api-reference/workspace/invites/create-batch) endpoint now accepts an optional seat_type field to specify the seat type (e.g., workspace_member, workspace_admin) for all invited users in a bulk operation.Mobile SSO reliability improvements: Fixed a regression where SSO login on mobile would get stuck on "Authenticating..." after a user logged out and attempted to sign in again. Also fixed workspace switching for mobile SSO users who sign in via SAML or OIDC providers.
Music
Section duration control: The [generate music detailed](/docs/api-reference/music/compose-detailed) endpoint now supports respect_sections_durations (boolean), which controls whether the model adheres to the duration specified for each section in the composition plan.
ElevenCreative Studio
Chapter visual content indicator: Chapter response models now include a has_visual_content boolean field indicating whether the chapter contains visual content.Text shadow and outline styles: ElevenCreative Studio text styling now supports text_shadow and text_outline options via the new StudioTextStyleShadowModel and StudioTextStyleOutlineModel schemas, enabling richer visual text customization within ElevenCreative Studio projects.Media generation clip task type: The PendingClipTask.type enum now includes the media_generation value, expanding clip task categorization to cover media generation workflows.

ElevenAgents, ElevenCreative and ElevenAPI
We’re moving from a single-product perception (“ElevenLabs”) to a platform-based structure with clearly defined product families:
ElevenAgents (Formerly Agents Platform)ElevenCreative (Formerly Creative Platform)ElevenAPI (New, the Developer Platform)
You'll already see this reflected in the docs and SDK readmes.
Global servers out of beta
Global routing is now the default rather than opt-in.
Previously the default ElevenLabs API server was located in the United States, with an opt-in beta for routing traffic through the Netherlands or Singapore based servers. As of now global routing is the default, meaning that the server will automatically be chosen based on geographic proximity to optimize latency.
The opt-in base URL api-global-preview.elevenlabs.io is now deprecated, please use the default api.elevenlabs.io base URL instead. If you're using the SDKs, this is already the default.
Text to Speech
TTS Normalizer v3.1: Upgraded the text normalizer to version 3.1, which includes improved accuracy and lower latency for text-to-speech conversion.
Agents Platform
Custom guardrails: Added support for user-defined output guardrails that allow you to create custom content filtering rules beyond standard moderation. Configure guardrails with a name, prompt instruction (up to 10,000 characters), and choice of evaluation model (gemini-2.5-flash-lite or gemini-2.0-flash). When triggered, the guardrail ends the conversation. See the [Create agent API reference](/docs/api-reference/agents/create#request.body.conversation_config.safety.guardrails.custom) for configuration details.WhatsApp outbound messaging: Added [Send outbound message](/docs/api-reference/whats-app/outbound-message) endpoint (POST /v1/convai/whatsapp/outbound-message) to initiate conversations via WhatsApp using message templates. Required fields include whatsapp_phone_number_id, whatsapp_user_id, template_name, template_language_code, template_params, and agent_id.Eleven v3 conversational model: Added eleven_v3_conversational to the available TTS models for agents, providing improved voice quality and expressiveness in agent conversations.Suggested audio tags: Added suggested_audio_tags field to TTS configuration for agents using v3 models. Define up to 20 tags (e.g., "happy", "excited") to guide expressive speech generation, with optional descriptions for when each tag should be used.Tool error handling: Added tool_error_handling_mode field to webhook tool configurations with options: auto (default, determines handling based on tool type), summarized (sends LLM-generated summary), passthrough (sends raw error), or hide (does not share error with agent).Dynamic variable sanitization: Added sanitize field (boolean, default false) to DynamicVariableAssignment. When enabled, the assignment value is removed from tool responses and transcripts while still being processed for variable assignment.Turn model selection: Added TurnModel enum with turn_v2 and turn_v3 options for selecting the turn detection model version.Workflow node transfers: Added is_workflow_node_transfer field (boolean, default false) to AgentTransfer schema for identifying transfers within workflow nodes.Transfer branch metadata: Added TransferBranchInfoTrafficSplit and TransferBranchInfoDefaultingToMain schemas for tracking branch routing information in agent transfers.Workflow node transition testing: Added workflow_node_transition assertion type for unit tests with UnitTestWorkflowNodeTransitionEvaluationNodeId schema to validate agent workflow transitions.
ElevenCreative Studio
Muted tracks endpoint: Added [Get project muted tracks](/docs/api-reference/studio/get-muted-tracks) endpoint (GET /v1/studio/projects/{project_id}/muted-tracks) that returns a list of chapter IDs with muted tracks in a project.
Workspaces
Lite member seat type: Added workspace_lite_member to the SeatType enum for workspaces with limited access permissions.Content templates resource: Added content_templates to WorkspaceResourceType enum for sharing content templates within workspaces.
