How to post parameters array with retrofit?

Question

I want to post parameter array.

My parameters look like this :

Request
{
                "ProcName" :"BR_SP_BRN_GET_STORE_ACTIVE_SHIPMENTS",
                "Parameters": [
    {
      "Name": "StoreCode",
      "Value": "B201"
    }
  ]
}

And my api interface class like this :

@FormUrlEncoded
@POST("GetDispatchList")
Call<TransferCenterStoreResponse> TRANSFER_CENTER_STORE_RESPONSE_CALL(
        @Header("Authorization") String authHeader,
        @Field("ProcName") String procName,
        @Field("Parameters") List<TransferCenterStoreParameters> objects) ;

How can i do this with retrofit? Any advice or sample code ?
