Hi everyone,
I'm fairly new to the Now Experience and currently working on a SIR Workspace where I need to add a button that:
- Triggers an asynchronous REST call to an external service.
- Once the call completes, reloads the data in a Data Resource called "Look up data 1" [look_up_data_1] attached to the "Rich text 10" [rich_text_10].
Right now, I’ve implemented this using a UI Action with the following setup:
- Checked Workspace Form Button and Workspace Client Script.
- In the Workspace Client Script, I use GlideAjax to call a Script Include, which then triggers the REST call via RESTMessageV2.
- I’ve also configured the REST Message, HTTP Method, and a System Property to load the endpoint configuration.
This setup works, but I’d like to move this logic into UI Builder, using a Button component, so it’s fully integrated with Workspace and more maintainable, and be able to reload content of Data Resource.
Unfortunately, I’m not sure how to:
- trigger the REST call from the Button component.
- wait for the response.
- then reload the Data Resource.
Here’s the current Workspace Client Script for reference:
function onClick(g_form) {
var sysId = g_form.getUniqueValue();
var ga = new GlideAjax('Custom_ScriptInclude');
ga.addParam('sysparm_name', 'triggerAjax');
ga.addParam('sysparm_security_incident_sysid', sysId);
ga.getXMLAnswer(function(response) {
g_form.reload();
});
}
Any guidance or examples on how to achieve this in UI Builder would be greatly appreciated!
Thanks in advance!
