Telegram Start Parameter
A query parameter passed to a bot or mini-app via deep-link: t.me/<bot>?start=<value> opens the chat and triggers /start with the value, or t.me/<bot>/<short_name>?startapp=<value> launches the mini-app with start_param available in Web App initData. Used for routing inside mini-apps (e.g. share-link to specific screen, deep-link from web to TG context, attribution). Telegram Ads Spy uses startapp for share-creative flow: pasting a /ads/<id> link inside Telegram opens our mini-app on that exact creative.
