Creating your Telegram Application

We welcome all developers to use our API and source code to create Telegram-like messaging applications on our platform free of charge.

In order to ensure consistency and security across the Telegram ecosystem,
all third-party client apps must comply with the API Terms of Service.

Obtaining api_id

In order to obtain an API id and develop your own application using the Telegram API you need to do the following:

  • Sign up for Telegram using any application.
  • Log in to your Telegram core:
  • Go to ‘API development tools’ and fill out the form.
  • You will get basic addresses as well as the api_id and api_hash parameters required for user authorization.
  • For the moment each number can only have one api_id connected to it.

We will be sending important developer notifications to the phone number that you use in this process, so please use an up-to-date number connected to your active Telegram account.

Using Telegram's open source code

Everyone is welcome to use our open source code. We have included a sample API id with the code. This API id is limited on the server side and is not suitable for apps released to end-users — using it for anything but testing purposes will result in the API_ID_PUBLISHED_FLOOD error for your users. It is necessary that you obtain your own API id before you publish your app.

Please remember to publish your code as well in order to comply with the GNU GPL licences.
