How to start a workflow without any callUrl to daily? I want it in my own frontend

You can start a Vapi assistant conversation directly in your frontend using the Vapi Web SDK, without needing a callUrl or external telephony provider. For example:

javascript
import Vapi from "@vapi-ai/web";
const vapi = new Vapi({ apiKey: "YOUR_API_KEY" });
vapi.start(assistantOptions);

This runs the conversation in your web app ([docs](https://docs.vapi.ai/documentation/get-started/make-a-web-call)). Clarifying question: Are you looking to trigger a specific workflow (built in the Vapi workflow builder) from your frontend, or do you just want to start a general assistant conversation in the browser?

not working...

i know how to fix it

Hey Adrian! You just need to pass workflow ID as 4th parameter to Vapi web SDK initialisation code, or transient workflow as 5th parameter, and the first 3 parameters as NULL. It's all because of how parameters are currently being passed to the SDK, but I will do the rework and make it easier as an object type.
