Telegram link to chat with text

Question

Can I create telegram link with preset text just like Whatsapp did?

I couldn't find any of tips on the net.

I had tried this. It only open up telegram without text

tg://to=@username&text=presettext

Answer 1

I don't know if this worked before, and I couldn't find any official description of such a format, but now the format that works is similar to the one used in WhatsApp:

https://t.me/contact?text=text

This works both using the username (without @) and using the phone number (with +).

Answer 2

Now you can use draft_text param
