Watch out for

Time zone mismatches between the user's local time and Google Calendar can cause wrong event times so always specify the timezone explicitly in the API call.
Telegram message handlers may drop updates if they take too long to process so implement a quick acknowledgment reply before performing heavy LLM or calendar operations.
Google Calendar API requires proper OAuth2 scopes for write access so ensure your service account or user credentials have the correct permissions enabled.
Email delivery delays can make users think their booking failed so include a unique tracking ID in the email body and log the send status immediately.
