In addition to the fact that the network is already full of information about various kinds of Telegram bots, the messenger opened its API for developers, and now everyone can create their own bot. Today, I would like to talk about an equally cool feature in Telegram, namely bots. Moreover, no one will have access to your messages. One of the main 'tricks' of Telegram is its supposed security - according to Pavel Durov, all correspondence between users is encrypted. Then, click on the top left burger menu and find the Cloud Function.Telegram has become popular these days and has more than 500 million users. 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. 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. 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. If you recognize yourself in 1., Telegram offers detailed documentation on how to set up your webhook. 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. Run go test in the test file folder to run the test
