Hey @fireproofsocks you’re very close to the right answer! The Context and Plugs section there shows how to set the Absinthe Context from plug, and pass in values from the conn.

Specifically, the function here:

  def build_context(conn) do
    with ["Bearer " <> token] <- get_req_header(conn, "authorization"),
    {:ok, current_user} <- authorize(token) do
      %{current_user: current_user}
    else
      _ -> %{}
    end
  end

could be amended to add any other value that you want. Say for example you want the client IP address just do:

%{current_user: current_user, client_ip: conn.remote_ip}

What might be tempting to do but I recommend avoiding is to just pass the whole conn into the context. Extract what you actually need for your logic, set that in the context, and go from there.
