Amarula.Content.Options (amarula v0.4.3)

View Source

An incoming interactive message that presents a set of choices — a list menu, a buttons message, a template-button message, or a native-flow interactive message. These are what WhatsApp Business / call-center / automated flows send to ask "pick one of these". A normal linked-device client can't send them, but it receives them; the user's reply comes back as an %Amarula.Content.Response{}.

The four proto shapes are unified into one:

  • :kind — :list | :buttons | :template | :interactive.

  • :title — header/title text, if any.
  • :body — the main prompt text.
  • :footer — footer text, if any.
  • :button_text — the label that opens the option list (list messages only).
  • :options — the choices, each %{id, text, description} (description is nil for kinds that don't carry one). id is what your app keys the user's selection off; it matches the id of the later %Amarula.Content.Response{}.

For anything beyond the choices (media headers, native-flow param JSON, …), read msg.raw.
