ElevenLabs

ElevenAgents Merge and search triage tickets: Merge tickets folds up to 50 open tickets from the same agent into one target ticket. Merged tickets keep the status merged and reference the target through merged_into_ticket_id. List tickets and List workspace tickets add a case-insensitive search parameter that matches ticket titles, descriptions, comments and turn comments, and each result includes a search_match excerpt showing where the query matched. Workflow End node outcomes: Workflow End nodes accept an outcome of success (default) or failure, so a workflow can record whether a conversation ended successfully. The conversation error type adds workflow_end_failure. Call queueing enabled for new agents: New agents are created with call queueing enabled unless platform_settings.queueing_config.enabled is set explicitly. Existing agents keep their current setting. Post-call audio webhook retries: When Enable retries is on, post_call_audiowebhooks are retried on the same schedule as transcription webhooks. Audio payloads over 50 MiB are not retried, and queued audio retries are capped at 400 MiB per webhook. Strict tool overrides: The conversation override tool_ids_strict makes an overridden tool_ids list the complete set of tools available in the conversation, including tools on workflow nodes. It is ignored when set on the agent itself. Widget end confirmation: The widget can ask users to confirm before ending a chat or call. Enable it with end_confirmation_enabled in the widget configuration or the end-confirmation attribute. Text to Speech Audio effects: Text to Speech and Text to Dialogue requests accept an optional audio_effects object. It applies a filter preset, perceived distance, a reverb environment, a looped background noise bed and stereo panning to the generated audio. List valid preset, environment and background noise IDs with GET /v1/audio-effects/catalog. Reverb and non-zero panning produce stereo audio and are rejected for ulaw_*, alaw_* and pcm_* output formats. Effects do not change the cost of a request. Speech to Text Turn prediction commit strategy: The realtime Speech to Text WebSocket adds turn_prediction as a commit_strategy value. In addition to silence-based segmentation, it commits a segment as soon as the model predicts the speaker has finished their turn. It is the default for models that predict turns, and partial transcripts from those models include turn_probability. See transcripts and commit strategies. Voices Voice collections API: Voice collections can now be managed through the API. Create, list, update and delete collections, and add or remove voices. See List voice collections. Workspaces Basic seat fallback: Update member accepts allow_downgrade_to_basic_seat. When unlocking a user whose original seat type has no seats available, the user is moved to a basic seat instead of the request failing. Workspace ID on user: Get user returns the workspace_id of the workspace the API key belongs to. SDK releases JavaScript SDK v2.72.0 - Added clients for voice collections, the audio effects catalog and triage ticket merging. Text to Speech and Text to Dialogue methods accept audio_effects, triage ticket list methods add search and filters, and the realtime Speech to Text client adds the turn_prediction commit strategy. Python SDK v2.72.0 - Added clients for voice collections, the audio effects catalog and triage ticket merging. Text to Speech and Text to Dialogue methods accept audio_effects, triage ticket list methods add search and filters, and the realtime Speech to Text client adds the turn_prediction commit strategy. play() and save() now accept any iterable of audio chunks, such as a list or tuple. RealtimeEvents.CLOSE handlers receive a dictionary with the WebSocket close code and reason; handlers without parameters continue to work. ElevenLabs CLI v1.5.0 - Regenerated API commands, adding voice collections, the audio effects catalog, triage ticket merging and agent merge proposals. Packages @elevenlabs/client@1.27.0 and @elevenlabs/react@1.17.0 - Added a previousText option to Scribe.connect() and useScribe() in microphone mode. The text is sent with the first audio chunk to give the model context, such as existing document text, for casing, punctuation and sentence continuation. MediaDeviceOutput now receives libsampleratePath, so output resampling uses the same custom libsamplerate bundle path as MediaDeviceInput. @elevenlabs/react-native@1.2.29 - Updated to @elevenlabs/client@1.27.0 and @elevenlabs/react@1.17.0. @elevenlabs/convai-widget-core@0.19.0 and @elevenlabs/convai-widget-embed@0.19.0 - Added an optional confirmation dialog before ending a chat or call, enabled with the end-confirmation attribute or end_confirmation_enabled config, with customizable text. Added carousel rich content with scrollable item cards that can include an image, subtitle, description and actions. Carousels remain in the transcript after a reply, without their actions. Rich content is now shown during voice calls when the transcript is visible. API

ElevenAgents Structured procedures compile on save and publish: Update agent and Create agent draft now compile and validate structured procedures automatically. Integrations no longer need to call the compile endpoint or manually update the generated workflow. Invalid procedures return per-procedure errors as 400 procedure_validation_failed. Agents without structured procedures are unaffected. Compile procedures endpoint is legacy: Compile procedures is marked legacy and should not be used by new integrations. It remains available for existing callers. Merge proposals: Merge proposals are available in alpha. Teams can open a proposal for an agent branch, review configuration changes and test results, leave comments or approval decisions, and merge approved changes into a target branch. See Merge proposals. SDK releases JavaScript SDK v2.71.0 - Added clients for agent merge proposals, deployment history, test invocation cancellation and Speech Engine duplication. The release also adds triage ticket priorities and sorting, batch call export limits, gpt-6.1-sol, claude-sonnet-5-5, Eleven v4 agent voice models and current agent configuration types.

Regenerated the API client with Flows template endpoints and current schema types. API

Image & Video Sora 2 and Sora 2 Pro retired: OpenAI is discontinuing the Sora API on September 24, 2026. Both models have been removed from the Image & Video model picker and stop generating on that date. Existing generations remain available in your history. Flows and templates that use a Sora node need to be switched to another video model, such as Gemini Omni 1.1 Flash, before they can run again. Seedance 1.5 Pro deprecated: ByteDance retires Seedance 1.5 Pro on November 11, 2026. The model is no longer offered for new generations and will stop working on that date. Use a Seedance 2.0 model instead.

The client sends both file and files fields for compatibility, and React exposes the updated client API. API

ElevenLabs CLI The ElevenLabs CLI v1.0.0 is now available. Every ElevenLabs API operation is available as a subcommand, with JSON, table, YAML and CSV output, automatic pagination and shell completion. The CLI also provides local configuration workflows for ElevenAgents. Store agent, tool and test configurations as files, synchronize them with push and pull commands, manage branches, run tests, install ElevenLabs UI components and select a data residency region. Procedures Procedures are now generally available in ElevenAgents. A procedure contains task-specific instructions and a trigger that determines when they apply. During a conversation, the agent loads the relevant procedure, allowing one agent to handle distinct tasks without placing every instruction in its system prompt. Use free-form procedures when the agent can adapt the wording or order of instructions. Use structured procedures when steps must run in a defined order. Both types can be used alongside workflows on the same agent. ElevenAgents Conversation triage tickets: Added APIs for creating tickets about agent performance, creating manual follow-up tickets, listing tickets, assigning workspace members, updating status and assignee, and adding ticket-level or turn-level comments. Conversation observability: Realtime clients can receive a context_usage event after each completed agent turn. The event reports the model, prompt token count and model context limit. SDK Releases JavaScript SDK v2.65.0 - Added clients and types for conversation triage tickets and lightweight conversation summaries. Conversation APIs add procedure, invalid-tool-call and sort filters; procedure APIs add agent version selection; topic APIs add evaluation detail controls and frustration sorting.

WebRTC now uses the selected input device, preserves mute state when switching microphones and fails setup if initiation data cannot be sent. The widget adds concurrency queue status, optional language selection on the collapsed trigger and first-message rendering for agents that support both text and voice. API

MCP server Local MCP server deprecated: The local ElevenLabs MCP server and MCP player are deprecated in favor of the hosted MCP server. Both repositories are archived and will no longer receive updates. The hosted server is available at https://api.elevenlabs.io/v1/mcp, signs in with your ElevenLabs account through OAuth and requires no local installation or API key. See the hosted MCP server documentation for setup instructions for Claude, Cursor and other MCP clients.

ElevenCreative Image, video and speech generation APIs: New asynchronous Flows APIs create, list and retrieve video, image and speech generations. Generation responses expose pending, generating, completed and failed states, and requests can include a webhook target for completion events. Reusable media assets: New asset APIs upload, list, retrieve and delete workspace media. Image, video and audio references can use an uploaded asset, a previous generation or inline base64 data, allowing generation jobs to be chained. See References and assets. ElevenAgents Lightweight conversation summaries: Get conversation summary returns the generated title, transcript summary, call outcome and plain user or agent messages without loading the full transcript. The optional max_messages query parameter is an integer from 1 to 200 (default 40); longer conversations set messages_omitted to true. Useful for agents that need to preserve context. Conversation topic pagination and sorting: Get agent conversation topics adds optional cursor pagination and sorting. Use page_size (integer, 1–100), cursor (string), sort_by (conversations, sentiment or success_rate) and sort_direction (asc or desc). Responses add has_more and nullable next_cursor. Concurrency wait queues: Agent platform settings add optional queueing (AgentQueueingConfig). Set enabled to true to hold callers when the agent reaches its concurrency limit; wait_timeout_seconds is an integer up to 1,800 (default 180). Turn and workflow controls: Turn configuration adds merge_with_default_ignore_terms (boolean, default false) to combine custom interruption terms with curated defaults. Soft timeouts add disable_until_first_user_message (boolean, default false), and workflow tool locators add optional schema_overrides for per-node parameter overrides. Background audio defaults: BackgroundSoundConfig.volume now defaults to 0.15 instead of 0.6, and crossfade_loop now defaults to true instead of false. Set these fields explicitly to retain the previous behavior. SDK Releases JavaScript SDK v2.64.0 - Added client.assets for uploading, listing, retrieving and deleting assets, plus client.flows for asynchronous video, image and speech generation.

Dubbing v2 API Dubbing v2 is now available through the API. It translates audio and video into more than 90 languages while preserving each speaker's voice, tone and pacing. The new project-based API keeps source transcripts and translations as editable JSON. Create a project from a file or URL, add one or more target languages, edit individual transcript segments or translations, then regenerate only the regions that changed. Follow the Dubbing quickstart to create your first dub. ElevenAgents Conversation guardrail filters: List conversations adds optional guardrail_types (GuardrailType[]) and custom_guardrail_names (string array) query parameters. The existing conversation hierarchy can now be filtered with optional parent_conversation_id (string).

API

ElevenAgents Test-specific tool mocks: Agent simulations and unit tests can now define tool_mock_overrides, keyed by tool ID, to replace shared mocks for one test. ToolResponseMockConfig also adds optional is_error (boolean, default false) so a mock can exercise tool-failure paths. Translated workflow messages: Literal Say node messages add text_translations, a map of language keys to TranslatedString objects. The field is optional on input and required on output, so strict response validators must accept it. Conversation version filters: List conversations and Text search conversation messages add the optional version_id query parameter (string) to filter results by agent version. Knowledge base system tool: Agent configuration adds a knowledge_base system tool with configurable enabled_strategies (SearchStrategy[]). Agent knowledge base RAG queries add optional use_agent_defaults (boolean, default true); set it to false to use neutral retrieval settings while retaining the agent's embedding model.

DTMF input redaction: DTMFInputConfig adds optional redact_input (boolean, default false) to replace caller keypad digits in transcripts, conversation logs and analysis. Digits repeated by the agent or passed to tools remain unchanged. Speech to Text Realtime entity detection: Scribe v2 Realtime adds the entity_detection query option. It accepts all, one entity type or category, or an array of types and categories, and emits detected entities in committed_transcript_entities events. See the entity detection guide for supported categories. Voices Voice replication across data residencies: Added POST /v1/voices/{voice_id}/replicate-to-isolated-environment for copying an Instant Voice Clone or Voice Design voice to a workspace in the same consolidated billing group. Requests require target_workspace_id (string) and accept preserve_voice_id (boolean, default true); responses return the target voice_id. Character metadata: Character responses add recommended_voice_ids (string array, default []), metadata adds nullable role (CharacterRole), and CharacterAge replaces middle-aged with middle_aged. SDK Releases Packages @elevenlabs/client@1.16.0, @elevenlabs/react@1.11.0, @elevenlabs/types@0.18.0, @elevenlabs/react-native@1.2.17 and @elevenlabs/convai-widget-core@0.15.0 - Added onAgentReasoningResponsePart, which receives streaming agent reasoning events with start, delta and stop types. @elevenlabs/convai-widget-core@0.15.0 and @elevenlabs/convai-widget-embed@0.15.0 - Added show_resize_button and the show-resize-button embed attribute. Set either to false to hide the widget header's expand and collapse control. @elevenlabs/client@1.17.0, @elevenlabs/react@1.12.0, @elevenlabs/types@0.19.0, @elevenlabs/react-native@1.2.18 and @elevenlabs/convai-widget-core@0.15.1 - Added the enableLogging option to Scribe.connect and useScribe.

MCP Server v0.12.1 - Includes the v0.11 tool updates and a dependency refresh that resolves 44 security alerts. v0.11.0 - Added simulate_conversation with configurable simulated-user behavior, evaluation criteria, transcript output and pass/fail analysis. The speech_to_text tool now defaults to scribe_v2, and voice_clone now sends audio file contents instead of path strings. API

ElevenAgents WhatsApp branch and environment overrides: Outbound WhatsApp messages and outbound calls now honor branch_id and environment passed in conversation_initiation_client_data. Overrides are validated before anything is sent — an unknown branch or environment is rejected with an error — and persist for the conversation, so a customer's reply resumes on the requested branch and environment. See the WhatsApp guide for examples. Procedure APIs: Added eight public, branch-scoped operations for managing procedures. You can create, list, retrieve and remove procedures; create, retrieve or discard draft changes; and compile procedure drafts into an agent workflow. Procedure creation accepts name, content, type and trigger. An empty trigger creates a sub-procedure, while an omitted or null trigger is derived from the procedure content. Knowledge base crawl jobs: Added APIs to create, list, inspect and cancel crawl jobs. Create requests require url (string) and support crawl depth, page limits, URL patterns, sitemap URLs, folder placement, automatic synchronization and removal of unavailable documents. Bulk knowledge base management: Added bulk dependency checks and bulk deletion for 1–20 unique document or folder IDs. Dependency checks support pagination and dependent_type; deletion returns an independent success or failure for each ID. Setting force: true also removes dependencies and recursively deletes non-empty folders. Batch call result export: Added Export batch call results to download recipients and conversation results from a terminal batch as CSV. Conversation filters and analysis data: List conversations and Text search conversation messages add optional visited_agent_ids and visited_agent_branch_ids array filters, each limited to 50 values. List requests also accept data_collection_ids and evaluation_criteria_ids to include corresponding results in each conversation summary. Summaries add optional data_collection_results, evaluation_criteria_results and tag_ids. Referenced analysis configuration: Agent platform settings add the optional, nullable analysis_items field, typed as AgentAnalysisItems, to attach evaluation and data-collection items by reference. A null value indicates that the agent still uses the legacy inline fields; an empty value indicates a migrated agent with no attached items. Procedure dependency metadata: Procedure references add trigger (string) and arrays for referenced_tool_ids, referenced_kb_ids, referenced_procedure_ids and referenced_dynamic_variables. WebRTC token response: Get WebRTC token responses now require conversation_id (string) in addition to token. This is a breaking schema change for clients that validate or deserialize the response shape. Knowledge base RAG results: KnowledgeBaseRagToolResultModel adds chunks (KnowledgeBaseRagChunkModel[]) for RAG-result-in-tool-result mode. Studio Draft project status: ProjectCreationMetaResponseModel.status adds draft. The project creation type now uses the shared ProjectCreationMetaType enum with the same existing values. Voices Voice accents: Added GET /v1/voices/accents to list the accents available in the shared voice library. Results can be filtered by language and model_id, and each accent returns its accent, language, code and human-readable name. The accent value can be passed to the accent query parameter on Get shared voices to filter shared voices. Workspaces Webhook usage reporting: WebhookUsageType adds Flows. SDK Releases JavaScript SDK v2.60.0 - Added voices.accents.get to list voice accents in the shared voice library, along with the ElevenAgents procedure, knowledge base crawl job and bulk management APIs and the referenced analysis configuration from the latest schema. Python SDK v2.60.0 - Added the voice accents, ElevenAgents procedure, knowledge base crawl job and bulk management APIs from the latest schema. Also fixed AsyncConversation startup so it no longer blocks, and corrected list-of-primitive multipart fields to be sent as repeated form fields.

Music Music Finetunes API: Added API support for managing Music Finetunes. Five endpoints let you create a Finetune from uploaded audio, list accessible Finetunes, retrieve training status, update metadata and visibility, or delete a Finetune. All music generation SDK methods now expose finetune_id. ElevenAgents Resolve external conversation references: Added GET /v1/convai/conversations/resolve to resolve a Slack message URL or Zendesk ticket URL to a conversation. Requests require agent_id and reference query parameters (strings). Query agent knowledge bases: Added POST /v1/convai/agents/{agent_id}/knowledge-base/rag-query for read-only RAG queries against an agent's knowledge base. The request requires query (string), accepts optional branch_id (string), and returns ranked chunks with document, chunk, text and vector-distance metadata. This endpoint is excluded from generated SDKs. Knowledge base content formats: Knowledge base file, text and URL responses add optional content_format (html | markdown, default html). Agent voice configuration: TTS override schemas add optional client-overridable model_id (TTSConversationalModel). The default for enable_phoneme_tags changes from false to true.

WhatsApp typing indicators: WhatsApp account request and response schemas add optional enable_typing_indicator (boolean). Speech to Text Single-use batch authentication: Convert speech to text adds optional token (string) as an alternative to API key or bearer authentication. Create the single-use token with POST /v1/single-use-token/batch_scribe; it expires after 15 minutes. Realtime client reliability: @elevenlabs/client now reports microphone setup and malformed server errors through RealtimeEvents.ERROR, releases microphone resources after setup failures and connection closure, and drops late microphone frames after socket teardown. Text to Speech Archived pronunciation dictionaries: List pronunciation dictionaries adds optional include_archived (boolean, default true). Workspaces Webhook event subscriptions: Update workspace webhook requests add optional events (WorkspaceWebhookEventType[]) with voice_library_removal_notice, speech_to_text and agent_qa. Webhook responses can return the subscribed event list. Usage analytics dimensions: Get workspace usage adds surface and actor to the group_by values. Clear service account limits: Update service account API key accepts character_limit: "clear" to remove a monthly character limit, alongside "no_update" and integer values. Alerting webhook references: Alerting webhook notifier schemas now identify a workspace webhook with required webhook_id (string) instead of embedding url, method and headers.
