[image] sahilpaudel: I want to get just the id and name from the object the rest of the data are irrelevant to me. What have you tried so far?

I don’t know where to start I tried this but obviously it failed def format_response({ok, response}) do response |> Enum.flat_map(fn params -> show(params) end) end def show(%{"id" => id, "name" => name}) do %{ id: id, name: name } end

When it fails, You should always include error messages. Also, it looks like a list of map, but You use it with tuple syntax. Why Enum.flat_map? Enum.map should do the trick as well.

[image] sahilpaudel: |> Enum.map(fn x -> %{id: x.id, name: x.name} end) This would have worked too |> Enum.map(& %{id: &1.id, name: &1.name}) BTW “id” is not equal to id:, but the working code uses :id…

|> Enum.map(fn x -> %{id: x.id, name: x.name} end)

This seems to have worked
