Delete user by userId

Asynchronous. Deletes a specific user by <code>userId</code>. Does not prevent future data collection about the user. If multiple users share the same <code>userId</code>, they'll all be deleted. This endpoint can be used to delete users from email-based projects, userID-based projects, and hybrid projects.<br/><br/>On Iterable's API Documentation page, this endpoint does not work for <code>userId</code> values that contain a <code>/</code> character. In such cases, you can still call this endpoint with a tool like curl or Postman, or from your code.
