Scripted rest api

Hi,

I have a requirement to create RITM using scripted rest api. The values should be passed as json.

Any leads to do this would be highly appreciated.

TIA!

Hi Ruchi,

I believe you want to create a scripted REST API which would be consumed by 3rd party team. they would send information/variable data as json request corresponding to the variables you share with them. This will be only for single catalog item I consider

Example: if your catalog item has 4 variables as requested_for, requested_by, start_date, end_date

you can inform them to send data as below; so the json request would look like

{

"requested_for":"Abel Tuter",

"requested_by":"Fred Luddy",

"start_date":"2020-04-23",

"end_date":"2020-04-35"

}

Now example script in scripted rest API to create RITM for your catalog item with the above variable data

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {

var reqbody = request.body.dataString;

try{
var parser = new global.JSON();
var parsedData = parser.decode(reqbody);

var requestedFor = parsedData.requested_for;
var requestedBy = parsedData.requested_by;
var startDate = parsedData.start_date;
var endDate = parsedData.end_date;

var cartId = GlideGuid.generate(null);
var cart = new Cart(cartId);

// give here the sys_id of the catalog item under which those variables are present

var item = cart.addItem('4054428fdb151f0097679ec6db9619c0', 1);

//fill in the variables on the request item form
cart.setVariable(item,"requested_for", requestedFor); 
cart.setVariable(item,"requested_by", requestedBy);
cart.setVariable(item,"start_date", startDate); 
cart.setVariable(item,"end_date", endDate);

var rc = cart.placeOrder();

// rc is the request number; you can query RITM table and get the RITM number

var reqNumber = rc.number;

var ritm = new GlideRecord('sc_req_item');
ritm.get('request.number', reqNumber);
var ritmNumber = ritm.number;

var res = {};
res["status"] = "Success";
res["requestNumber"] = reqNumber;
res["requestItemNumber"] = ritmNumber;
response.setBody(JSON.stringify(res));

}
catch(ex){
var res = {};
res["status"] = "Error";
res["message"] = ex.message;
response.setBody(JSON.stringify(res));
}

})(request, response);

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

There is OOTB API set up for service catalog already: https://developer.servicenow.com/dev.do#!/reference/api/orlando/rest/c_ServiceCatalogAPI

If that doesn't fit your need, I recommend using cartJS in a custom scripted REST API: https://developer.servicenow.com/dev.do#!/reference/api/orlando/server/sn_sc-namespace/c_CartJSScope...
