# delete

> Delete a subproject.

Delete a subproject.

### Schema

```yaml
openapi: 3.1.0
info:
  title: API
  version: 1.0.0
paths:
  /api/projects/{id}:
    delete:
      operationId: subpackageProjects_delete_subproject
      summary: Delete a subproject
      description: >-
        Deletes a subproject.


        Only subprojects can be deleted through this API. Deleting the
        root/parent project

        returns `422 only_subprojects_can_be_deleted`. A project must have no
        phone numbers

        before it can be deleted; otherwise the request returns `422
        phone_numbers_must_be_removed`.


        On a successful delete, the subproject's registry brands and campaigns
        are migrated up

        to the parent project.


        Use this operation only for a subproject that is ready to retire. The
        Compatibility API cannot close an account; its [Update
        account](/docs/compatibility-api/rest/accounts/update-account) operation
        only renames one, so deleting the subproject here is the API path for
        retiring it.


        #### Permissions


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