# Context

> Reference information for the context object provided by the UI extensions SDK.

The `context` object in the UI extensions SDK contains data related to the authenticated user and HubSpot account, along with data about where the extension was loaded.

## Access context data

You can access context data using either approach:

* **Props-based approach:** destructure `context` from the callback passed to `hubspot.extend()`, then pass it to your component as a prop.
* **Hook-based approach:** call the [`useExtensionContext`](/apps/developer-platform/add-features/ui-extensions/ui-extensions-sdk/hooks#useextensioncontext) hook directly within your component.

## Fields

The `context` object has the following fields.

### Universal fields
