Stripe without using a shopping cart

It’s not that I am getting errors, I am stuck with the workflow process. I stuck right at the beginning when following the tutorial ‘Getting Started with Stripe Integration in Wappler’.

I am trying not to create a Shopping cart, and not sure how to go about just adding a single product (project) in my case straight to the payment page, with custom project_id field so that I can received it back through a web hook.

In the tutorial by @Teodor, it refers to multiple products for the Server-side integration, but my processes much simpler and need only one product. I am not sure how to go about this? I want to use the Server-side setup so I can pass through custom parameters for the product. I don’t need a shopping cart.

I am really stuck.
