Substitute variable to Rest Message endpoint from script include/business rule

[John_123_Snow]

Is it possible to substitute variable to endpoint for Rest Message? I need to pass sys_id of attachment into Delete HTTP method. I have something like this:

and in my script include and I have this: 

deleteAttachment: function (helloAttachmentSysID) {
	var request = new sn_ws.RESTMessageV2('hello eBonding', 'Delete Attachment');
        request.setStringParameter("sys_id", helloAttachmentSysID);
	var response = request.execute();
	var responseBody = response.getBody();
	var httpStatus = response.getStatusCode();
}

and of course in the business rule I am passing sys_id into deleteAttachment(helloAttachmentSysID);

but I cant seem to know how to pass it into that endpoint that current sys_id? what am I doing wrong?

I know I can do something like 

var endpoint = 'attachment/sys_id/endpoint/' + current.sys_id;

request.setEnpoint(enpoint); but I do not want to overwrite that...and would like to use the feature of substituting.

How do I achieve this?

Hi John,

You're missing the $ which allows for substitution

Your actual script is fine, it's just the endpoint missing the $ which is meaning your variable isn't being correctly substituted.
