FAQPage Schema

How do I create custom tools for voice assistants to perform actions during calls?▼

To create custom tools for voice assistants, you define function tools and API integrations that execute server-side logic. You wire these tools to fetch data, automate tasks, and interact with external services during real-time call workflows.

What are function tools and how do they work with API integrations in real-time call workflows?▼

Function tools are definitions that empower voice assistants to execute specific actions by connecting to API integrations. They work by triggering server-side logic during calls to fetch data or manage tasks across external platforms like calendars and messaging services.

Can I use custom tools to manage call control actions like transferring or ending calls?▼

Yes, you can use custom tools to manage call control actions during real-time workflows. The tools support transferring, ending calls, and DTMF interactions, allowing the voice assistant to directly manipulate the call state based on conversation logic.

How do I integrate a voice assistant with external calendars, spreadsheets, and messaging platforms?▼

You integrate a voice assistant with external calendars, spreadsheets, and messaging platforms by defining custom function tools. These tools wire API integrations to the external services, allowing the assistant to fetch and update data in real-time during calls.

What do I need to start building a tool server for voice assistant API integrations?▼

To start building a tool server for voice assistant API integrations, you need your VAPI_API_KEY and a structured server definition. You begin by creating a function tool via a POST request to your tool endpoint to establish the connection.

What safety considerations should I review when defining server-side logic for voice assistant tools?▼

When defining server-side logic for voice assistant tools, safety considerations involve managing access to external APIs and validating data fetched during calls. The structured workflow includes specific safety guidelines to ensure secure automation and call-control actions.
