Vapi is the Voice AI platform for developers.

Vapi AI

I’m dynamically assigning an `assistantId` via a webhook, and everything is working well technically — the webhook is firing, retrieving the caller info from Airtable, and returning an assistant ID.

However, I'm running into this error:

```
"Couldn't Get Assistant. `assistantId` bd083b2a-5ba8-45e6-b59f-f999977dfaab Does Not Exist."
```

The  ID in question refers to a **workflow**, not a standard assistant.

### ❓ My questions:

1
Does the `assistantId` field in the webhook response strictly require a Vapi Assistant ID, or is it also possible to return a Workflow ID there?

2
If only possible with assistantID, could it be an easy fix on your end to add workflow IDs? 


My use case requires assigning a workflowID dynamically through a Phone Number Server URL


Thanks in advance

i tried it with a squad ID as well (which could replace a workflow) but getting the same issue. 

When i try it with a regular Assistant and assistantID, the call works, no errors

The assistantId field in the webhook must be a Vapi Assistant ID or an inline config. workflow IDs are not supported and will cause the “Does Not Exist” error; to use a workflow dynamically, link it to an assistant in the dashboard and return that assistant’s ID..
