# 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`](/docs/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

| Field | Type | Description |
| - | - | - |
| `location` | `'crm.record.tab'` \| `'crm.record.sidebar'` \| `'crm.preview'` \| `'helpdesk.sidebar'` \| `'settings'` \| `'home'` | The UI extension's location. |
| `portal.id` | Number | The ID of the HubSpot account. |
| `portal.timezone` | String | The account's timezone. |
| `portal.dataHostingLocation` | `'na1'` \| `'na2'` \| `'na3'` \| `'ap1'` \| `'eu1'` | Geographic identifier that denotes the region where the current portal is hosted. See [HubSpot Cloud Infrastructure FAQ](https://knowledge.hubspot.com/account-security/hubspot-cloud-infrastructure-and-data-hosting-frequently-asked-questions) for more details. |
| `user.id` | Number | The user's ID. |
| `user.email` | String | The user's primary email address. |
| `user.emails` | Array | All of the user's associated email addresses. |
| `user.firstName` | String | The user's first name. |
| `user.lastName` | String | The user's last name. |
| `user.locale` | String | The user's locale. |
| `user.language` | String | The user's UI display language, as selected in their HubSpot profile preferences. Represented as a BCP 47 language code (e.g., `"en"`, `"de"`, `"fr"`). Note that this differs from `user.locale`, which controls date and number formatting — `language` reflects the actual UI language the user has selected in HubSpot. Defaults to `"en"` if the user has not opted into a non-English UI language. |
| `user.teams` | Array | An array containing information about teams that the user is assigned to. Each team object contains the `id` and `name` of the team, along with a `teammates` array that lists the IDs of other users on the team. |
| `user.permissions` | Array | An array of permission strings (e.g., `'integrations-management-write'`). |
| `variables` | Object | All of the project's [config profile](/docs/developer-tooling/local-development/build-with-config-profiles) variables. |

### CRM-specific fields

The following fields are only available in CRM extension points (`crm.record.tab`, `crm.record.sidebar`, `crm.preview`, `helpdesk.sidebar`):

| Field | Type | Description |

| `crm.objectId` | Number | The ID of the CRM record (e.g., contact ID). |
| `crm.objectTypeId` | String | The ID of the CRM record's object type (e.g., `0-1`). See the [full list of object IDs](/docs/api-reference/latest/crm/understanding-the-crm#object-type-ids) for reference. |
