Create the client's Vapi assistant from the inbound answering template and save a secret-free local client record. Reuses an existing local record by default.

Render a local template with the client's settings and PATCH the existing Vapi assistant. Optional overrides are deep-merged last.

Update selected first-message, system-prompt, model, and voice fields while preserving the assistant's other model settings and attached tool IDs.

Bind an existing Vapi phone-number ID, or create/import a number from a provider-specific Vapi REST body. The client assistantId is always enforced.

Create reusable Vapi tools and/or attach existing tool IDs, preserving current assistant model configuration. Supports transfer, callback, calendar, CRM, API-request, and MCP tool payloads accepted by Vapi.

Create structured outputs attached to the client assistant. With no definitions, uses the template schema for name, number, reason, callback window, and transfer outcome.

Place a real, potentially billable outbound call using the client assistant. Requires explicit confirmation. Optionally poll and return transcript and structured data.

Read the local client record and current Vapi assistant, bound phone, and latest call. Partial remote failures are returned in errors.
