Hi Aditya,

The parameter for quantity is sysparm_quantity, Service Catalog API - POST /sn_sc/servicecatalog/cart/{cart_item_id} . And i am able to update the quantity on the cart item by setting sysparm_quantity

I am seeing below error , after adding syspam_quantity

{
  "error": {
  "detail": "",
  "message": "Security constraints prevent ordering of Item"
  },
  "status": "failure"
}

Once Items has been added to cart, how we can do checkout with Postman? i tried to take the result of the POST (add to cart) but i couldn't able to checkout with the data. I am getting an error message as below:

{
"error": {
"message": "Cannot checkout an empty Cart",
"detail": ""
},
"status": "failure"
}

How can i checkout with the data which i added in cart?

Hi Aditya, Which sys_id are you providing in the request?

You   have to provide the sys id of the catalog item
