Telegram advanced techniques

Using the template system
Feel free to use all the features of the Template system in Telegram step!
Processing system commands
Telegram bots have /commands, so add them in BotFather (using /setcommands) and create one scenario which triggers new objects from TMessageIn, and if there is no system commands in text field, the scenario sends an object to Router scenario.
That is essential. The best bot architecture includes only one scenario which triggers new TMessageIn objects.
Context-based architecture
Router scenario (it does not triggers by events, it is invoked) is routing messages, based on the value of the field context in TChat object.
Condition step (checking context) looks like:
Multi-context architecture
You can add as many fields in TChat structure (e.g. subcontext) and compose conditions on them. That is a way to create multi-context architecture.
Dealing with files, images and userpics
Step 1. Getting temporary file path
Call Telegram API-method getFile using Telegram step this way:
Then, save to a field temporary URL: https://api.telegram.org/file/bot_BOT_TOKEN_/{{API_response.file_path}}, where _BOT_TOKEN_ is token of your bot.
Step 2. Saving file to Directual
Use internal SDK method $D.fs.download (it can be applied both in SDK step and in Edit object step)
