Send POST request with parameters in body via Play WS API

Currently, I am sending get requests via the Play WS API as follows: 

wsClient
    .url(myUrl)
    .withQueryString(getParams(): _*)
    .get()

Now I want to change this call to use HTTP Post. When calling the following:

    wsClient
        .url(myUrl)
        .withMethod("POST")
        .withBody(getParams(): _*)
        .get()

I receive the following error:

Cannot write an instance of Seq[(String, String)] to HTTP response. Try to define a Writeable[Seq[(String, String)]]

I guess it's because the method getParams returns Seq[(String, String)].

How can I fix this?

When using http post key value pairs are sent using content type application/x-www-form-urlencoded

Here is the code for posting

 client.url(myUrl)
    .withHeaders("Content-type" -> "application/x-www-form-urlencoded")
    .post(getParams.map { case (k, v) => s"$k=$v"}.mkString("&"))
