docs: // DeleteRequest sends an DELETE API Request to urlStr with optional body.
  // It is a shorthand combination for Client.NewRequest with Client.Do.

  // Relative URLs should always be specified without a preceding slash.
  // If specified, the value pointed to by body is JSON encoded and included as the request body.
