I'm using Vapi Squads with transient assistants (full configuration passed inline, not stored). My tool endpoints need to identify which team/account the call belongs to. My question: 1. Can I manually set an id field on a transient assistant definition that will be passed through to tool calls? 2. If not, what's the recommended way to map transient assistants to a team/account when they call tools? 3. Should I use metadata, the assistant name, or a different approach? Context: - I have 3 transient assistants in one squad (router + 2 specialists) - All need to access the same team's data when calling tools

You cannot set a custom

id

field on a transient assistant. The recommended approach is to encode your team/account in the assistant's

name

field, then extract it in your tool endpoint. For example:

json
{
  "assistant": {
    "name": "team-123-router",
    "model": { ... },
    "voice": { ... }
  }
}

Parse the

name

to identify the team when processing tool calls. (See documentation: [Vapi Server URL Events](https://docs.vapi.ai/server-url/events)) Source: - [Vapi Server URL Events](https://docs.vapi.ai/server-url/events)
