beans.scala - class contains connection to server

 lazy val ConnectionFlow: Flow[HttpRequest, HttpResponse, Any] =
    Http().outgoingConnection(config.getString("host"), config.getInt("port"))

  lazy val AppService = new Service(config, ConnectionFlow)

Service.scala class

def Request(request: HttpRequest): Future[HttpResponse] =
    Source.single(request).via(ConnectionFlow).runWith(Sink.head)

//building Json request 
val reqJs = Json.obj("PARAMS" -> Json.obj("param1" -> value1))

Request(RequestBuilding.Post("/services/serviceName",reqJS).flatMap { response =>
// need response to be in JSobject format but the service returns application/xml format

If I understand correctly, you're asking how to modify the request s.t. it indicates to the server it expects a JSON response.

To do that, you can try

val builder = RequestBuilding.Post("/services/serviceName",reqJS)
builder.addHeader(Accept(MediaRange(`application/json`)))
// send out the request as you did

According to https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept, Accept Header only advertisers which content types the client is able to understand, while it is fully on the server's mercy to respect this request. That being said, the server could literally respond with anything they want, despite the header you send.
