request.MultipartForm() is only for incoming requests, not for outgoing.

You will have to use multipart.NewWriter() and add the fields to that. Then you can either use io.ReadAll to read the body into a byte slice and use request.SetBody() to set it as body or use request.SetBodyStream(). Don't forget to call request.Header.SetMultipartFormBoundary() with the return value of multipart.Writer.Boundary().
