# Create a subproject

POST https://%7BYour_Space_Name%7D.signalwire.com/api/projects
Content-Type: application/json

Creates a subproject under the authenticated root project.

Creating a project is only allowed when authenticated as a top-level (root) project.
A subproject cannot itself contain subprojects, so attempting to create one while
authenticated as a subproject fails with `422 nested_subprojects_not_allowed`.

The response includes the `signing_key`. This is the only time it is returned — it
cannot be retrieved through the API afterward, so capture it from this response.

#### Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Management_.

            The client sends HTTP requests with the Authorization header
            containing

            the word Basic followed by a space and a base64-encoded string of
            project_id:token.

            The project ID will be used as the username and the API token as the
            password.


            Example:

            ```

            Authorization: Basic base64(project_id:token)
