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.
Support of Bot-3.5 API
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.
{-# LANGUAGE OverloadedStrings #-}
import Network.HTTP.Client (newManager)
import Network.HTTP.Client.TLS (tlsManagerSettings)
import Web.Telegram.API.Bot
main :: IO ()
main = do
let 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!"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.

chatId = ChatId <chat_id> -- use ChatId 10231 or ChatChannel "<@channelusername>"
message = "text *bold* _italic_ [github](github.com/klappvisor/haskell-telegram-api)"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 (Just True) Nothing Nothing NothingUsing default instance:
let request = sendMessageRequest (ChatId int64_chatId) "text" -- only with required fieldslet request = (sendMessageRequest ChatId int64_chatId) "text") {
message_disable_notification = Just True -- with optional fields
}Contributions are welcome!
- Fork repository
- Do some changes
- 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_TOKENis the token obtained from BotFather and must be defined as environment variablePAYMENT_TOKENis the token obtained from BotFather and must be defined as environment variableCHAT_IDcan be id of your chat with your bot. Send some messages to this chat in Telegram and docurl "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_NAMEis the name of your botHSPEC_ARGSare the normalhspecarguments 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.
