# canOpen

A Boolean value that indicates whether the app can open the external link account.

```
static var canOpen: Bool { get async }
```

## Discussion

Check this property before showing any user-interface controls that enable people to open the external link account.

Don’t check this property again in response to user input; instead, call [`open()`](/documentation/StoreKit/ExternalLinkAccount/open()) immediately.

> Important:
> Only show user-interface controls that call the ``doc://com.apple.storekit/documentation/StoreKit/ExternalLinkAccount/open()`` method if this property is `true`. The ``doc://com.apple.storekit/documentation/StoreKit/ExternalLinkAccount/open()`` method always throws an error when ``doc://com.apple.storekit/documentation/StoreKit/ExternalLinkAccount/canOpen`` is `false`.
