I need to pass two parameters to my end point, along with the request so that would make it three and only two are allowed per my http post request. I tried the HttpParams but that does not work in my case. The situation is when product is chosen a size must be chosen as well. It works when I add url plus end point and append the Id. I then add Id to my end point, I have already tested it, product is added to cart. There are different sizes for each product so a size must me chosen. Once I get the issue with the parameter figured out I will update the item by Id this is the reason I need both parameters. I can’t append the size and Id I will get an error.
