High-level bindings to the Telegram Bot API based on servant library.
Both getUpdates request or webhook can be used to receive updates for your bot.
Inline mode is supported.
Uploading stickers, documents, video, etc is not supported yet, but you can send items which are already uploaded on the Telegram servers.
There are two ways of using Telegram Bot API. First and original way is to run IO directly for every Telegram servers request, another one is based on TelegramClient which is just ReaderT.
Use TelegramClient
{-# LANGUAGE OverloadedStrings #-}
importNetwork.HTTP.Client (newManager)
importNetwork.HTTP.Client.TLS (tlsManagerSettings)
importWeb.Telegram.API.Botmain::IO()
main =dolet token =Token"bot<token>"-- entire Token should be bot123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11
manager <- newManager tlsManagerSettings
result <- runTelegramClient token manager $do
info <- getWebhookInfoM
let request = setWebhookRequest' "https://example.com/hook"
isSet <- setWebhookM request
getMeM
print result
print"done!"
Running IO directly (planning to deprecate this option)
⚠️ This method to interact with a Telegram bot is about to be depricated and all new API calls will only have their M versions. You can run them using runTelegramClient function, for example runTelegramClient token manager $ sendMessageM message or in example below replace getMe token manager with runTelegramClient token manager getMeM to get the same behavior.
getMe example
{-# LANGUAGE OverloadedStrings #-}
importNetwork.HTTP.Client (newManager)
importNetwork.HTTP.Client.TLS (tlsManagerSettings)
importWeb.Telegram.API.Botmain::IO()
main =do
manager <- newManager tlsManagerSettings
res <- getMe token manager
case res ofLeft e ->doputStrLn"Request failed"print e
RightResponse { result = u } ->doputStrLn"Request succeded"print$ user_first_name u
where token =Token"bot<token>"-- entire Token should be bot123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11
sendMessage example
{-# LANGUAGE OverloadedStrings #-}
importNetwork.HTTP.Client (newManager)
importNetwork.HTTP.Client.TLS (tlsManagerSettings)
importWeb.Telegram.API.Botmain::IO()
main =do
manager <- newManager tlsManagerSettings
let request = sendMessageRequest chatId message
res <- sendMessage token request manager
case res ofLeft e ->doputStrLn"Request failed"print e
RightResponse { result = m } ->doputStrLn"Request succeded"print$ message_id m
print$ text m
where token =Token"bot<token>"-- entire Token should be bot123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11
chatId =ChatId<chat_id>-- use ChatId 10231 or ChatChannel "<@channelusername>"
message ="text *bold* _italic_ [github](github.com/klappvisor/haskell-telegram-api)"
Note on requests:
Many request data records have a lot of optional parameters which are usually redundant.
There are two ways to create requests:
With data type constructor:
let request =SendMessageRequest (ChatId int64_chatId) "text"Nothing (JustTrue) NothingNothingNothing
Using default instance:
let request = sendMessageRequest (ChatId int64_chatId) "text"-- only with required fields
let request = (sendMessageRequest ChatId int64_chatId) "text") {
message_disable_notification =JustTrue-- with optional fields
}

Fork repository

Create pull request
Wait for CI build and review

PROFIT
Bear in mind that the CI build won't run integration test suite against your pull request since the necessary environment
variables ($BOT_TOKEN, $STRIPE_TOKEN, $CHAT_ID and $BOT_NAME) aren't exported when a fork
starts the build (for security reasons). If you do want to run them before creating RP, you can setup integration of your fork
with CircleCI.
You can use stack to build project
stack build
To run test you have to create your own bot. Go to BotFather and create the bot. As the result you will have private bot's access token. Keep it safe!
stack test --test-arguments "--integration -c CHAT_ID -b BOT_NAME -- HSPEC_ARGS"
where
BOT_TOKEN is the token obtained from BotFather and must be defined as environment variable
PAYMENT_TOKEN is the token obtained from BotFather and must be defined as environment variable
CHAT_ID can be id of your chat with your bot. Send some messages to this chat in Telegram and do curl "https://api.telegram.org/bot<replace_with_token>/getUpdates", you'll have to parse some JSON with your brain ;-) or any other suitable tool and you will find chat id there.
BOT_NAME is the name of your bot
HSPEC_ARGS are the normal hspec arguments you can find here
The help option is available for the tests and for hspec:
stack test --test-arguments "-h"
stack test --test-arguments "--integration -c CHAT_ID -b BOT_NAME -- -h"
Note: Inline Spec is disabled for now...
If everything is fine after running the tests you will receive a few new messages from your bot.
