complete booking process without checkout page

Hi Thanks for reaching WCMp Support!!

In general, the customer cannot buy/book anything without checkout in WooCommerce.

However, in order create your own custom module, you have to add your own checkout flow by overriding woocommerce checkout process by using their hook and filter. You can refer to their GitHub for further assistance: https://github.com/woocommerce/woocommerce

Let us know if you have any further query.
