Hi OpenAI team,
We see that the current Agentic Checkout / Commerce documentation mainly describes product purchases (with fields like id, title, price, currency, quantity, etc.).
Is there any supported or recommended way to handle vacation rentals or other booking-based use cases, where we need fields like from_date, end_date, or number of guests?
In other words, can the checkout API accept custom fields or metadata for these dynamic, time-based products — or is the schema currently limited to fixed products only?
Thanks in advance for clarifying — we’re exploring how to adapt the new commerce flow for vacation rental bookings.
