Answer 1

You need to add

 @SerializedName("yourInputParameter")

in your bean(model) class for your request body

For example

 public class YourClass{
       @SerializedName("yourInputParameter") String yourInputParameter;

       ...
     }

it will work

because now retrofit unable to read your request body because proguard(minifyEnabled) is true

after adding @SerializedName in your request body it will definitely work for you
