# List Resource Types

> Returns the resource types supported by the connected provider for permission checks.

```
GET /unified/list_resource_types
```

Returns a list of resource type identifiers that the connected provider supports for [Check Permissions](/permissions-check/api-reference/check-permissions) calls. Use these values as the `resource_type` component when constructing resource IDs, or to understand what types of resources you can check permissions for.

<Note>
  This endpoint is distinct from `GET /unified/iam/resource_types` in the [IAM section](/iam/api-reference/resource-types/list-resource-types). That endpoint returns types for IAM resource-scoped user queries; this one returns types for permission checks. The valid values may overlap but serve different purposes.
</Note>

No provider API call is made — the response is a static list declared by the connector.

## Authentication

Requires `Authorization: Basic {base64_encoded_api_key}` and `x-account-id: {account_id}`. See [authentication](/iam/common-guide/basic-authentication-with-stackone-api).

## Response

Returns an object with a `data: string[]` field containing resource type identifiers. Pass the values in `data` as the `resource_type` component in a composite resource ID, or use them to understand which types can be checked.

Common values: `file`, `folder`, `drive`, `channel`, `workspace`, `message`, `page`.
