# StopApplication


Stops the application from processing data. You can stop an application only if it is in the running status, unless you set the `Force` parameter to `true`.

You can use the [DescribeApplication](API_DescribeApplication.md) operation to find the application status. 

Managed Service for Apache Flink takes a snapshot when the application is stopped, unless `Force` is set to `true`.

## Request Syntax


```
{
   "ApplicationName": "string",
   "Force": boolean
}
```

## Request Parameters


The request accepts the following data in JSON format.

 ** [ApplicationName](#API_StopApplication_RequestSyntax) **   <a name="APIReference-StopApplication-request-ApplicationName"></a>
The name of the running application to stop.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 128.  
Pattern: `[a-zA-Z0-9_.-]+`   
Required: Yes

 ** [Force](#API_StopApplication_RequestSyntax) **   <a name="APIReference-StopApplication-request-Force"></a>
Set to `true` to force the application to stop. If you set `Force` to `true`, Managed Service for Apache Flink stops the application without taking a snapshot.   
Force-stopping your application may lead to data loss or duplication. To prevent data loss or duplicate processing of data during application restarts, we recommend you to take frequent snapshots of your application.
You can only force stop a Managed Service for Apache Flink application. You can't force stop a SQL-based Kinesis Data Analytics application.  
The application must be in the `STARTING`, `UPDATING`, `STOPPING`, `AUTOSCALING`, or `RUNNING` status.   
Type: Boolean  
Required: No

Length Constraints: Minimum length of 1. Maximum length of 64.
