# AddApplicationInput
<a name="API_AddApplicationInput"></a>

 Adds a streaming source to your SQL-based Kinesis Data Analytics application. 

You can add a streaming source when you create an application, or you can use this operation to add a streaming source after you create an application. For more information, see [CreateApplication](API_CreateApplication.md).

Any configuration update, including adding a streaming source using this operation, results in a new version of the application. You can use the [DescribeApplication](API_DescribeApplication.md) operation to find the current application version.
