Cloud-based messaging app Telegram provides free, open and secure communication across any platform with automatic chat synching across devices. Telegram also provides a dedicated Bot API for building custom bots that users can interact with via messages and commands to perform predefined tasks.
Most developers view an API as a technical boundary – one they use to access the functionality of another component or service in order to improve their own offering. Combining several technical components together leads to an improved over all product for end-users. Open APIs, however, serve a far wider purpose within the current communications industries – they provide not just a technical boundary, but also an economic one.
