Phoenix and Webhooks mode.

[prtngn]

Hi. How I can use bot in Webhook mode with phoenix project?

[tbm206]

I too wanted to ask a similar question. In my case, I was able to use the stateless mode in a Phoenix project but I'm also interested in the statefull mode.

My use case is to collect information sequentially and hence I need to keep state somewhere. More, the Telegram API doesn't allow to attach this state in ForceReply for example?

It's a great library BTW 🎉

Hi @tbm206.
I think your use case in not directly related to Phoenix / webhook interactions.

If you need a statefull chat, no matter if you interface via polling or webhook with the telegram servers, you can use a Telegram.ChatBot behaviour. This will give you a "per chat" state out of the box.

Or even using the "stateless" Telegram.Bot behaviour, you can manage "your state" leveraging whatever persistency (db, ets/dets, etc.).

But keep in mind is that the Telegram.ChatBot behaviour it's more natural (and correct) way of interacting with a user over a 1-1 chat, a session, where every user interact with a single Telegram.ChatBot process.

Please open a new discussion if you need help on the statefull topic

Hi @prtngn.

The current webhook library interface is designed to start an HTTP server and setup a webhook

The Telegram.Webhook operating mode starts an HTTP server (cowboy) that will receive the webook notification requests from the telegram server. The app is meant to be served over HTTP, a reverse proxy should be plance in front of it, facing the public network (public IP address) over HTTPS. Refer to the Telegram.Webhook module docs for more info.

The library takes care to setup Plug.Cowboy with a Telegram.Webhook.Router.

Personally I've not planned an integration with phoenix to serve the webhook endpoint there.

Well, if I have time, I'll try to make a module to work with the phoenix.

I also would love to see this integrated with Phoenix, reusing its Plug pipelines.

Added in 9170d29 some documentation about how to directly integrate the webhook endpoint in an existing phoenix / plug application facing the internet.

In version 2.0.0 the plug integration has been refined. Check out the documentation
