Need to be able to create a cart for a user through zapier.
I would then be able to add items to this cart through zapier.
When ready to check out, I can generate an invoice for this cart via zapier and get back the url.
I could get the payment status of this cart.
I could get notified when this cart has been paid
I would use this cart in my chatbots to make a more robust chatbot billing platform.
