Multistep Product Customizer

Hope someone can help. I have a potential client that needs me to build a multistep “product builder” that allows customers to basically select a few different conditions that will eventually lead them to adding a “custom” product to the cart and checking out via Woocommerce. The problem I’m facing is that I believe this may require use of JSON API which I am just not advanced enough in to understand. I’m wondering if there’s an alternative, perhaps a plugin that has enough flexibility to match the exact needs of the client. The product isn’t a physical object but rather a ticket to a venue. The customizable options (conditions) include date, number of people and optional equipment.
