ElevenAgents

Workspace-wide conversation tickets: Added List workspace tickets to retrieve conversation triage tickets across accessible agents. Filter by status or assignee and use cursor pagination to retrieve up to 100 tickets per page.
Dynamic variable conversation filters: List conversations and Text search conversation messages now accept repeatable dynamic_variable_params filters. Use name:op:value with eq, gt, gte, lt or lte; comparison operators require numeric values.
Twilio answering machine detection: Outbound telephony and batch call configurations now support optional twilio_machine_detection. Choose enable for an early human-or-machine verdict or detect_message_end to wait for a voicemail greeting to finish. Results arrive through the new answering_machine_detection webhook event.
Data collection value constraints: Data collection properties can now use allowed_values to name a dynamic variable containing the permitted values. The previous allowed_values_dynamic_variable field is deprecated.
Agent metadata: List agent branches responses now indicate when a draft was created and whether it predates the branch tip. Agent and Speech Engine summaries now require voice_id.
Knowledge base source URLs: Agent RAG query chunks now include required nullable source_url, containing the tracked URL for URL documents.
Agent response attachments: agent_response WebSocket events now include optional attachments. Each attachment requires url and name and can include mime_type.

Workspaces

API key platform limits: Service account API key responses can now include enterprise platform_limits for credits, Professional Voice Clones, and TTS, Dubbing, and Music concurrency.
