<CanAccess />

<CanAccess> is the component form of useCan.

It internally uses useCan's return values to provide its functionality.

Passes the given properties to the can method from your access control provider. After, if it returns true, it renders the children, otherwise, if it returns false, it renders fallback prop if provided. Otherwise, it renders null.

To learn more about authorization, check out the Authorization guide and Access Control Provider documentation.

Basic Usage​

By default, the CanAccess component will infer the current resource and the action based on your route automatically. id will also be inferred if the current route includes one.

So if you are at the /posts route, CanAccess will check authorization for the posts resource and the list action.

For /posts/show/:id route, the action will be show.

import { CanAccess } from "@refinedev/core";

const MyComponent = () => (
<CanAccess fallback={<CustomFallback />}>
<YourComponent />

Usage with props​

You may have a case like in the /posts/show/:id page, where, inferred resource is posts and action is show, but you want to authorize a different resource eg. category.

In this case, you can explicitly pass props to the CanAccess component for authorizing a different resource.

import { CanAccess } from "@refinedev/core";

export const MyComponent = () => {
return (
<CanAccess resource="posts" action="delete">


It also accepts all the properties of useCan.


Callback to be called when useCan returns false.

onUnauthorized={({ resource, reason, action, params }) =>
`You cannot access ${resource}-${} resource with ${action} action because ${reason}`,
<YourComponent />


Component to render if useCan returns false. If undefined, it renders null.

<CanAccess fallback={<div>You cannot access this section</div>}>
<YourComponent />


Accepts UseQueryOptions<CanReturnType> to customize the caching behavior of the underlying query.

<CanAccess queryOptions={{ cacheTime: 25000 }}>
<YourComponent />
