Yes. Use the 'create_event' tool. Fantastical's engine is designed to parse phrases like 'Lunch with Bob at 1pm next Tuesday'. The agent will transmit the string and return the structured event data flawlessly.
How do I see my available scheduling links (Openings) via chat?
Use the 'list_openings' tool. Your agent will retrieve all your active scheduling pages, providing the booking link URLs and duration settings so you can share them with others easily.
Can I suggest multiple meeting times to someone through the agent?
