You can certainly build a Script Include which the Client Script will call, which would have the Script Include itself calling the REST API and then passing the results back down to the Client.

You would do this through a "combination client script" leveraging GlideAjax which includes both Client executable code and server executable code.

Please mark as correct answer if this solves your issue.

Try the following steps:

1. Navigate to System Web services -> Outbound -> Rest Messages, open the Http methods for the api which created and scroll down to related links to click "Preview Script usage" and copy the script.

2. Go to script include -->New
Name: integrationClientUtilities
Client callable: true
Accessible from: All application scopes
Script:

var integrationClientUtilities = Class.create();
integrationClientUtilities.prototype = {
initialize: function() {},

apicall: function() {
var asset = this.getParameter('sysparm_asset'); //value from client
var asset_name; //get the asset display name
var get_asset = new GlideRecord('alm_asset');
if (get_asset.get(asset)) {
asset_name = get_asset.display_name.toString();
}
//Paste the script which copied in Step 2
try {
var r = new sn_ws.RESTMessageV2('Integration', 'method post');
r.setStringParameterNoEscape('Asset', asset_name);
r.setStringParameterNoEscape('Type', 'outbound');
var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();
gs.info("header " + httpStatus);
gs.info("body " + responseBody);
if (httpStatus == 200)
return 'success'; //In case if you want store the output in the form, you should parse response body

} catch (ex) {
var message = ex.message;
}
},

type: 'integrationClientUtilities'
});

3. Open the catalog item to create new catalog client script

Name: onChange Asset call API
Type: onChange
UI Type: All
Variable Name: Asset
Script:

Yes, you can trigger an outbound REST API call using a Catalog Client Script in ServiceNow.

A Catalog Client Script is a script that runs on the client-side (i.e. in the user's web browser)

Here is another example:.

/*To trigger an outbound REST API call using a Catalog Client Script, you can use the XMLHttpRequest object or the fetch API to send an HTTP request to the desired API endpoint. Here's an example of how to use fetch to send an outbound REST API call from a Catalog Client Script:*/ javascript Copy code function onSubmit() { var myData = { // Data to send to the API endpoint // ... }; fetch('https://example.com/api/endpoint', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify(myData) }) .then(response => response.json()) .then(data => { // Handle the API response data // ... }) .catch(error => { // Handle the API error // ... }); }
