URL: https://developers.vsee.io/use-cases/browser-call-sdk

Use the VSee Browser Call SDK to embed video calling directly into your app. Control the call UI entirely using the VSee ID and token from the SSO response.

## Step 1: SSO with vsee fields
POST /users/sso (auth: API Key + Secret)
Call SSO with ?fields=vsee to get data.vseeid and data.vsee_token for the Browser Call SDK.
headers:
- X-ApiKey (required) — API Key
- X-ApiSecret (required) — API Secret
- X-AccountCode (required) — Account code
queryParams:
- fields (required) — Must be 'vsee' to get SDK credentials
bodyFields:
- first_name (required) — Patient's first name
- last_name (required) — Patient's last name
- type (required) — User type: 200 = Patient
- email — Patient email address
- code (required) — Unique patient identifier on your end (max 128 chars)

## Step 2: Initialize the SDK
Use data.vseeid and data.vsee_token from Step 1 to initialize the Browser Call SDK. This gives you full control over the video call UI.

## Step 3: Start or join a call
Use the SDK methods to start a new call or join an existing room. Refer to the Browser Call SDK documentation for the full API reference.
