# List Applications

GET https://YOUR_SPACE.signalwire.com/api/laml/2010-04-01/Accounts/{AccountSid}/Applications

Lists the account's Applications, which provide reusable voice and messaging routing. These applications are also available as addressable [cXML Applications](/docs/apis/rest/cxml-applications/list-cxml-applications) in the SignalWire REST API. Use this collection for code built around Application SIDs.

#### Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Voice_ or _Messaging_ or _Fax_.

[Learn more about API scopes](/docs/platform/your-signalwire-api-space).
