API publications that do not use auto-approve must be manually approved by an administrator after creation.

## Request body

- CreateApplicationRegistrationRequest
  - `api_id` string, uuid, required: The ID of the API the application is registering for.
  - `status` 'approved' | 'pending': The status of the application registration. It must be a valid status value for a registration creation.
  - `additional_data` FormResponseInput: The developer's answers to a custom form, as a map from each field's `name` to its value. Built-in fields like `full_name` and `email` go in their own top-level properties, not here.
