Package VersionHex Docs

Installation

gleam add telega_wisp

Usage

telega_wisp provides a handle_bot middleware that plugs into your Wisp request handler. It validates the secret token, decodes incoming Telegram updates, and dispatches them to your bot.

import wisp.{type Request, type Response}

import telega.{type Telega}

import telega_wisp



fn handle_request(req: Request, telega: Telega(session, error)) -> Response {

  use <- telega_wisp.handle_bot(telega:, req:)



  // Your other routes here...

  wisp.not_found()

}

The middleware will:

  1. Check if the request matches the bot's webhook path
  2. Validate the x-telegram-bot-api-secret-token header
  3. Decode the update and pass it to the bot asynchronously
  4. Return 200 OK immediately so Telegram doesn't retry
