# GetApplication
<a name="API_app-registry_GetApplication"></a>

**Note**  
 AWS Service Catalog AppRegistry will no longer be open to new customers starting July 30, 2026. If you would like to use AppRegistry, sign up prior to that date. Existing customers can continue to use the service as normal. For more information, see [AWS Service Catalog AppRegistry availability change](https://docs.aws.amazon.com/servicecatalog/latest/arguide/app-registry-availability-change.html).

 Retrieves metadata information about one of your applications. The application can be specified by its ARN, ID, or name (which is unique within one account in one region at a given point in time). Specify by ARN or ID in automated workflows if you want to make sure that the exact same application is returned or a `ResourceNotFoundException` is thrown, avoiding the ABA addressing problem.
