manage_call
Manage Call
Create, retrieve, or delete Vapi voice calls. Create outbound phone calls or web calls using a specific assistant. Retrieve call details including status, transcript, recording URLs, and cost breakdown.
Ask your agent in plain language. Each of these maps to a real tool on the server.
manage_call
Create, retrieve, or delete Vapi voice calls. Create outbound phone calls or web calls using a specific assistant. Retrieve call details including status, transcript, recording URLs, and cost breakdown.
manage_assistant
Create, update, retrieve, or delete a Vapi voice AI assistant. Assistants combine a transcriber, LLM, and voice to handle voice conversations. Use this to configure assistant behavior including first message, system prompt, voice settings, model, and turn-taking behavior.
list_calls
List voice calls in your Vapi account. Filter by assistant, phone number, or timestamps. Returns call metadata including status, type, duration, and costs.
get_call_transcript
Retrieve the full transcript, recording URL, analysis summary, and conversation messages for a specific call. Use this to access post-call artifacts after a call has ended.
list_assistants
List voice AI assistants in your Vapi account. Supports pagination and filtering by creation or update timestamps.
list_files
List files uploaded to your Vapi account. Files can be used as knowledge sources for assistants' retrieval-augmented generation.
manage_campaign
Create, update, retrieve, cancel, or delete outbound call campaigns. Campaigns use an assistant or squad and a list of customer numbers. Use list_campaigns to discover existing campaigns.
manage_squad
Create, update, retrieve, or delete a Vapi squad. Squads orchestrate multiple assistants with context-preserving transfers, enabling workflows where specialized assistants handle different parts of a conversation.
manage_tool
Create, update, retrieve, or delete tools that assistants can invoke during conversations. Configure function and direct API request tools with the typed fields, or use configuration for other current Vapi tool types such as endCall, handoff, and transferCall. Use list_tools to discover reusable tool IDs.
list_phone_numbers
List phone numbers provisioned in your Vapi account. Returns phone numbers across all providers (Vapi, Twilio, Vonage, Telnyx, BYO) with their routing configuration.
manage_phone_number
Create, update, retrieve, or delete phone numbers for inbound and outbound calling. Supports Vapi-managed numbers, Twilio, Vonage, Telnyx, and BYO (bring your own) phone numbers. Assign assistants or squads to handle inbound calls.
manage_workflow
DEPRECATED — use manage_assistant or manage_squad instead. Vapi retired Workflows on August 18, 2026. This tool is retained for compatibility and no longer performs operations.
download_call_artifact
Download a call recording, video, logs, or packet capture through the authenticated Vapi download endpoint. The call must have generated the requested artifact.
list_campaigns
Discover outbound campaigns with status and page-based pagination before managing a campaign.
manage_file
Upload a text knowledge-source file, retrieve file metadata, rename a file, or delete it. Use list_files to discover existing file IDs.
list_tools
Discover reusable Vapi tools and their IDs for assistant model.toolIds or manage_tool.
list_squads
Discover squads and their assistant members before managing squads or creating calls.
