Reference: https://ibkrcampus.com/docs/web-api/api-reference/trading/trading-fa-model-portfolios/is-full-master

## Authentication

- `Authorization` header (bearer token, required) — SSO bearer token.

## Servers

- `https://localhost:5000` (Client Portal Gateway, default)
- `https://api.ibkr.com` (Production)
- `https://qa.interactivebrokers.com` (Sandbox)

## Request

### Body (application/json)

This endpoint expects an object.

- `reqID` (long, required) — Request identifier to uniquely track a request.
- `subscriptionKey` (string, optional) — Subscription key. Send an empty string on the initial request.

## Response

### 200

Successfully retrieved the full-master status of the account.

- `isFullMaster` (boolean, optional) — True if the authenticated advisor is a full master account.
- `reqID` (long, optional) — Request identifier to uniquely track a request.
- `subscriptionStatus` (long, optional) — Describes if the model is in polling mode.

## Errors

### 400 Bad Request Error

- `any`

### 401 Unauthorized Error

Missing, invalid, or unparseable Authorization token.

- `status` (long, optional)
- `error` (string, optional)

### 500 Internal Server Error

internal server error, returned when incoming request cannot be processed. It can sometimes include subset of bad requests. For example, wrong accountId passed and it can only be detected later in handling request. Error contains reason of the problem.

- `error` (string, optional) — error reason

### 503 Service Unavailable Error

service is unavailable. For example if request takes more than 10s due to some internal service unavailability, request aborted and this status returned

- `error` (string, optional) — error reason
- `statusCode` (long, optional) — mimic response status code
