# Is Authorized Sync

> Check if a user has RBAC authorization for specific resources using the Stytch React Native SDK

export const organization = "Represents an instance or tenant in your application, typically mapping to each of your top-level customers.";

export const member = "Represents an individual end user's account within a given Organization, uniquely identified within that Organization by their email address.";

export const isReact_0 = true

{isReact_0 &&
<Info>
  In React, use the <a href="../../hooks/use-stytch-is-authorized"><code>useStytchIsAuthorized</code></a> hook to easily access the Member's authorization and react to changes.
</Info>
}

`rbac.isAuthorizedSync` is a synchronous method that returns an authorization verdict on a resource-action pair (that is, whether the logged-in <Tooltip tip={member}>Member</Tooltip> is authorized to perform the specified action on the specified Resource).

This method will use locally-cached instances of the Member and the configured RBAC policy. If the RBAC policy has not been loaded, this method will always return false. See the [SWR caching strategy](../../resources/swr-and-caching).

If the Member is not logged in, this method will always return `false`. If the resource or action provided are not valid for the configured RBAC policy, this method will return `false`.

If you need to asynchronously fetch guaranteed-fresh data from the API, use the [`rbac.isAuthorized`](./is-authorized) method.

<Note>
  As a best practice, authorization checks for sensitive actions should also occur on the backend.

## Parameters

<ParamField path="resource_id" type="string" required>
  The human-readable ID of the resource to check authorization for.
</ParamField>

<ParamField path="action" type="string" required>
  The action to take on the specified resource.
</ParamField>

## Response

<ResponseField name="authorized" type="boolean" required>
  `true` if the Member is authorized to perform the specified action on the specified resource, `false` otherwise.

  Will resolve to `false` if the RBAC policy has not been loaded or if the resource or action provided are not valid for the configured RBAC policy.
</ResponseField>
