RITM creation via REST API

[Shivani29]

Hi,

I am using POST method for Buy Item: 

https://xxxx.service-now.com/api/sn_sc/servicecatalog/items/{sys_id}/order_now

 and testing via postman. Below is the json I am passing via postman:

{

     "quantity": "1",

    "variables": {

        "Variable1": "value",

        "variable2": "value",

        "variable3": "value",

          }

}

All the mandatory fields are filled and when I test this, getting error in response body

"error": {

        "message": "Invalid Quantity value",

        "detail": ""

    },

    "status": "failure"

}

Can anyone pls help me out to get this issue resolved.

Thanks & Regards,

Shivani

@Shivani29  - Try replacing   "quantity": "1" with "sysparm_quantity": "1"

Hi @Shivani29 

Instead of quantity could you please use sysparm_quantity

See below -

{

     "sysparm_quantity": 1,

    "variables": {

        "Variable1": "value",

        "variable2": "value",

        "variable3": "value",

          }

}

Please mark my answer as correct and helpful if it works for you.

Hi @Shivani29 

Ensure that the quantity field is being sent as an integer rather than a string. You can modify your JSON to

{
    "quantity": 1,
    "variables": {
        "Variable1": "value",
        "variable2": "value",
        "variable3": "value"
    }
}

I hope my answer helps you to resolve your issue, if yes please mark my answer helpful and correct.

thank you

Rajesh

Hello @Shivani29 ,

The error you're seeing suggests that the quantity field is being passed incorrectly. For the REST API request to work properly, the quantity field should be sent as an integer, not as a string.

Here are two options you can try:

1. Send quantity as an integer:

   {
       "quantity": 1,
       "variables": {
           "Variable1": "value",
           "variable2": "value",
           "variable3": "value"
       }
   }
   

2. Use sysparm_quantity instead of quantity:

   {
       "sysparm_quantity": 1,
       "variables": {
           "Variable1": "value",
           "variable2": "value",
           "variable3": "value"
       }
   }
   ​

Either approach should resolve the "Invalid Quantity value" error. Let me know if you encounter any other issues!

Please Mark ✅Correct if this solves your query and also mark 👍Helpful if you find my response worthy based on the impact.

Hi @Shivani29 

In ServiceNow's REST API, the quantity might need to be passed as an integer instead of a string. Try removing the quotes around the quantity value, like this:

{
"quantity": 1,
"variables": {
"Variable1": "value",
"variable2": "value",
"variable3": "value"
}
}

Hi @Shivani29 

Replace quantity by sysparm_quantity should do the trick.

Invalid quantity value: Indicates that either the sysparm_quantity parameter is not provided or contains an invalid value.
