How to set up the cart
Before you start the cart integration, make sure that you read Catalog.
The StreamShop system is fully anonymous, so, your e-commerce must be able to receive a new anonymous cart.
The integration can be make in different ways, but the most common way is by query params.
Example:
https://www.yourwebsite.com.br/checkout/cart/add?sku=0000001&qty=3&sku=0000002&qty=4

If your e-commerce platform is ready to receive this kind of cart, send us the documentation, and we will be pleased to make this integration work! :)
