Behaviour for handling incoming WhatsApp webhook events.

Implement this behaviour in your application to receive and process webhook events dispatched by Anu.Webhook.Plug.

Example

defmodule MyApp.WhatsAppHandler do
  @behaviour Anu.Webhook.Handler

  @impl true
  def handle_event(:message_received, %Anu.Event.Message{} = event) do
    IO.puts("Message from #{event.from}: #{event.text}")
    :ok
  end

  @impl true
  def handle_event(:message_status, %Anu.Event.Status{} = event) do
    IO.puts("Message #{event.id} is now #{event.status}")
    :ok
  end
end
