Moshi ignore field in Kotlin

Use the @Transient annotation.

@Transient
private val your_variable_name: String

Doc here: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.jvm/-transient/index.html

Kotlin + Retrofit + Moshi

In case where you want to conditionally ignore fields, you can set it to null.

data class  User(var id: String,  var name: string?)

val user = User()
user.id = "some id"
user.name = null

The Json generated would be

user{
"id": "some id"
}
