Symptoms


When two-step checkout is enabled and when we use scripted web services to order an item (by passing in the custom cart with the sys_id of the item as a parameter to n_sc.CartJS), all items in the DEFAULT cart is being ordered instead of the specified item in the request body.

Cause


This is a bug in the platform and a PRB1297366 is created to fix the issue. 

 

Resolution


The dev team is working on a fix for this issue at the time of this writing (PRB1297366).
 
However, we have a workaround to resolve the issue.
 
WORKAROUND:
 
 we can make use of the OOB REST API named "Buy Item", which has this endpoint,
POST https://<instance-name>.service-now.com/api/sn_sc/servicecatalog/items/{sys_id}/order_now
 
One modification is required to get over the issue and it is to add this parameter along with other parameters to the request body,
 
'get_portal_messages': 'true'
 
Now it will directly order the item specified in the request body rather than all the items in the DEFAULT/portal cart.
 
To test the endpoint, please navigate to "System Web services" -> "REST" -> "REST API EXPLORER"
2. Select theNamespace -> sn_sc
3. Click on the API named "Buy Item (POST)"
 
4. Give the sys_id of the item being ordered.
5. Please provide variable values, if any, for the item.
6. Add the quantity (sysparm_quantity) and the above mentioned parameter, 'get_portal_messages': 'true'.
 
Click send.
 
Now we can see from the response that it orders only the item being specified and not all the items in the DEFAULT cart.
