# Create Application

`POST /applications/`

Create an application artifact only.

Returns an empty application without any variants or revisions.
Most callers should use `POST /simple/applications/` instead — it
creates the artifact, a default variant, and a first committed
revision in one request.
See the [Applications guide](/reference/api-guide/applications).

## Query parameters

- `application_id` string, uuid, nullable

## Request body

See the [Applications guide](/reference/api-guide/applications).
