Hello,
Seems it was my fault when trying to login the customer by sending username and password in the headers instead as json data.
I’ve manage to login the customer and using returned sw-token-context I was able to add a product to a cart without creating an empty cart.
Seems the cart is created automatically when the product is added and also using that sw-token-context the cart is assigned to the logged in customer.
The problem is now that after logging in into the storefront, I’m not able to see that cart. Is there a setting for this? Meaning when logs in to load last cart(is possible to be multiple created with API)
Best regards,
Sorin
