# create_checkout

Create a secure checkout for a chosen hotel room and return a getmyhotels.com URL where the guest completes payment. This does NOT charge the card — the guest pays on the hosted page. Confirm the hotel, room, dates, and price with the user before calling. Call get_checkout_quote first to confirm the live price.
