Hi @koop_g. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The usePermissions and useCan hooks in refine serve different purposes in handling authorization and access control. Here's a breakdown of their differences: 1. usePermissions: - This hook is part of the authentication system in refine. - It calls the getPermissions method from the authProvider. - It's used to retrieve the user's permissions or roles. - Typically used for broader authorization checks, like determining a user's role. Source 2. useCan: - This hook is part of the access control system in refine. - It calls the can method from the accessControlProvider. - It's used for more granular access control checks, typically for specific resources and actions. - Returns whether a user can perform a specific action on a specific resource. Source Example usage of usePermissions:

const { data: permissionsData } = usePermissions({
  params: { tenantId: "id" },
});

// Check if user has admin role
if (permissionsData?.includes("admin")) {
  // Do something for admin users
}

const { data: permissionsData } = usePermissions({
  params: { tenantId: "id" },
});

// Check if user has admin role
if (permissionsData?.includes("admin")) {
  // Do something for admin users
}

Example usage of useCan:

const { data } = useCan({
  resource: "products",
  action: "show",
  params: { id: 1 },
});

if (data?.can) {
  // User can perform 'show' action on 'products' resource
}

const { data } = useCan({
  resource: "products",
  action: "show",
  params: { id: 1 },
});

if (data?.can) {
  // User can perform 'show' action on 'products' resource
}

In summary, usePermissions is more about retrieving the user's overall permissions or roles, while useCan is used for checking specific access rights to resources and actions within your application.
