# POST /applications

`POST /applications`

Creates an Amazon Q Business application.

There are new tiers for Amazon Q Business. Not all features in Amazon Q Business Pro are also available in Amazon Q Business Lite. For information on what's included in Amazon Q Business Lite and what's included in Amazon Q Business Pro, see [Amazon Q Business tiers](https://docs.aws.amazon.com/amazonq/latest/qbusiness-ug/tiers.html#user-sub-tiers). You must use the Amazon Q Business console to assign subscription tiers to users.

An Amazon Q Apps service linked role will be created if it's absent in the Amazon Web Services account when `QAppsConfiguration` is enabled in the request. For more information, see [Using service-linked roles for Q Apps](https://docs.aws.amazon.com/amazonq/latest/qbusiness-ug/using-service-linked-roles-qapps.html).

When you create an application, Amazon Q Business may securely transmit data for processing from your selected Amazon Web Services region, but within your geography. For more information, see [Cross region inference in Amazon Q Business](https://docs.aws.amazon.com/amazonq/latest/qbusiness-ug/cross-region-inference.html).
