I am currently stuck with an implementation of a function that has to poll the Telegram API periodically and wait for a response from this. I guess there is some async / await magic that will help me to solve this problem in an elegant way. Maybe someone can jump in an give me a hint :wink: Other s…

:waving_hand: Have you considered using webhooks?

[image] idi527: Have you considered using webhooks? yep but i think it won’t help me very much.. I am using this in some browser automation where i will forward a two factor authentication code from sms to telegram to the login process handling.. so i will end up with something like that: F…

Ah, I seem to have misunderstood the question then … I’ve never used telegram’s polling api, but I guess the same principles as with webhooks would apply – in general, I abstract the polling / webhooks into a separate process which acts as a “telegram message producer” and allows other processes to…

I believe you should be returning a tuple from handle_info/2: def handle_info(:poll, state) do case get_updates(last_update_id) do [] -> Process.send_after(self(), :poll, 5000) {:noreply, state} new_messages -> state = handle_new_messages(state, new_message…

Nice, that looks like it goes into the right direction, thank you very much for the help :slight_smile: Quick additional Info: that programm is only used by me with a single chat id so I only need the last/one auth code and not a map of codes.. but I can adapt that to my needs.. Would you mind sho…

Note that 'mail' != "mail" in elixir, since the former is a charlist and the latter is a binary. Would you mind showing me an example on how I would integrate that Auther Module into my procedural browser automation code? Sure, maybe a blocking call would work fill_email_password("mail", "passw…

[image] idi527: Note that 'mail' != "mail" in elixir, since the former is a charlist and the latter is a binary. good catch.. edited my post to fix this..

[image] idi527: This can be achieved with Task.await , for example, where you’d call the Auther module to add a chat id to its internal state to wait an auth code for. And exactly thats the point where I am stuck. I couldn’t wrap my head around that. How would this look? Even after reading th…

I don’t think you need a looping async functions … I’d do something like # in Auther def wait_for_chat(server , chat_id, timeout \\ 5000) do GenServer.call(server, {:wait_for_chat, chat_id}, timeout) end @doc false def handle_call({:wait_for_chat, chat_id}, from, state) do # note that `Map.pu…
