REST API Issue for service-now catalog

[adityamadhira]

Hi I am planning to use REST API for service   catalog in C# and facing below issue while testing. Please help me to fix this issue -

To test I navigated to "REST API Explorer"   in service now. While testing Add Item To Cart   (POST) call fails. Please refer attached screen short.

Error -

{
  "error": {
  "detail": "",
  "message": "Invalid Quantity value"
  },
  "status": "failure"
}

Please help me what the issue is?

Did you ever get this error resolved?   I'm having the same issue.   Adding a catalog item to the cart with the API getting the same error.   When I set the sysparm_quantity value to 1 I get the same error.

Using the REST API Explorer withing ServiceNow I was able to get the sysparm_quantity variable to be passed, but now it's giving me another error:

Mandatory Variables are required

I looked at the catalog item.   When I go to that catalog item's form and right-click and select Configure variables, there is only one variable listed: service_offering.
