Then, click on the top left burger menu and find the Cloud Function. On Google Cloud console, first, select a project (create one if you’re new to Google Cloud). When the handler is called for the first time in a while, the cold start can take a few seconds.Īll major cloud providers provide function-as-a-service: Cloud Function on Google Cloud, AWS Lambda, and Azure Function on MS Azure.
The disadvantage is a potential higher response time. In response, it receives JSON containing all the messages. Given the nature of the webhook push mechanism, you’ re not charged if your bot is not used, which is nice compared to an always-on server. It works like this: when you start the application, it starts sending requests to the Telegram server, once every n seconds, at the following URL: where BotToken is your bot's token. We’ll use a cloud provider to deploy our handler as function-as-a-service, meaning you’re billed only when your handler actually uses resources. It is the de facto base for most of the bots out there. Even if it is not your approach for learning, please take a look at echobot.py. If you recognize yourself in 1., Telegram offers detailed documentation on how to set up your webhook. Our examples section contains several examples that showcase the different features of both the Bot API and python-telegram-bot. You also are comfortable with setting up certificates. You have your own server, and you know how to set up your handler to listen to a given port.Don’t worry you’re already 95% done by now. Let’s now deploy the handler and make your bot available on Telegram. Nice! All this code lives beautifully on our machine. Want to write more tests to ensure everything works as expected? Telegram does an fantastic job by providing developers with sample update JSON to use for our test cases, make sure to check them out on their documentation to build a robust handler. To check if someone has contacted the bot: def get_updates(offset=None): url = URL + "getUpdates?timeout=100" if offset: url += "&offset=".Run go test in the test file folder to run the test The libraries used are: import json import requests import urllibįirst you have to create the bot using BotFather ( ) However, if you want to make a bot in python without using specific libraries, this is the right article for you. To make a telegram bot there are a lot of libraries that allow you to do that.
