# Migration: App namespace

> Use types under the new App namespace

## Overview

The Attio SDK has migrated from individual type imports to a unified `App` namespace system. This provides better organization, improved autocomplete, and clearer API structure.

## What changed

### Before: Individual type imports

```typescript theme={"system"}
import type {
  RecordAction,
  BulkRecordAction,
  RecordWidget,
  CallRecordingInsightTextSelectionAction,
} from "attio/client"
```

### After: App Namespace

```typescript theme={"system"}
import type {App} from "attio"

// Types are now accessed as:
// App.Record.Action
// App.Record.BulkAction
// App.Record.Widget
// App.CallRecording.Insight.TextAction
```

## Migration steps

<Steps>
  <Step title="Update your imports">
    Replace individual type imports with the App namespace import:

    #### Before:

    ```typescript theme={"system"}
    import type {RecordAction} from "attio/client"
    ```

    #### After:

    ```typescript theme={"system"}
    import type {App} from "attio"
    ```
  </Step>

  <Step title="Replace your types">
    Replace individual types with the corresponding type under the `App` namespace:

    #### Before:

    ```typescript theme={"system"}
    export const myAction: RecordAction = {
      id: "send-invoice",
      label: "Send Invoice",
      icon: "Mail",
      onTrigger: async ({recordId}) => {
        // your logic
      },
    }
    ```

    #### After:

    ```typescript theme={"system"}
    export const myAction: App.Record.Action = {
      id: "send-invoice",
      label: "Send Invoice",
      icon: "Mail",
      onTrigger: async ({recordId}) => {
        // your logic
      },
    }
    ```
  </Step>
</Steps>
