Hello everyone, I have a class hierarchy like the following, and I have an API that return a list of User

I can retrieved Users using two different end-points,

The first one return recent users and the second one return popular users, for both popular and recent end-points the data returning by the API has the same structure except one thing

The recent end-point return a json like this, that differ from the popular end-point at the recent field

{
  "data": {
    "recent": { ... } // Here the difference
   }
}

And the popular end-point return a json like this, that differ from the recent end-point at the popular field

{
  "data": {
    "popular": { ... } // Here the different 
   }
}

Here the class hierarchy

@Serializable
data class ApiResponse(
  @SerialName("data")
  val apiData: Data
)

@Serializable
data class Data(
  @SerialName("recent") // My problem is here
  val page: Page
)

@Serializable
data class Page(
  val currentPage: Int,
  val from: Int,
  val perPage: Int,
  val results: List<User>,
)

For the Data class, there is a way to customize the behavior of the SerialName annotation to deal both with recent and popular name as the Page class has the same structure for recent and popular end-point without having to duplicate stuff ??

@Eric Ampire [MOD] you can add "popular" as second param to your Data data class and make them both default to null

depending on the API, appropriate field will be having your response data

there is an annotation to add multiple alternative names
