Creating actionable email links

The other day Chris Perry asked how to create a link in a notification to assign a record to themselves and load up the newly assigned record.

To do this you'd have change your email to the user, so show the link and then load a page that knew the task and have it redirect. This is what I came up with. A UI page with the following code does it.

<?xml version="1.0" encoding="utf-8" ?><j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null"> <g2:evaluate var="jvar_unwrapped_url" jelly="true"> var currentUser = gs.getUserID(); var incidentFromURL = RP.getParameterValue('incident'); var link = ''; var incident = new GlideRecord('incident'); if(incident.get('number', incidentFromURL)) { incident.setValue('assigned_to', currentUser); incident.update(); gs.addInfoMessage(incident.getDisplayValue() + ' has been updated.'); //gs.sendRedirect(incident.getLink()); link = incident.getLink(); } link || 'incident.do?sysparm_query=number=' + incidentFromURL; </g2:evaluate> ${gs.getMessage("Redirecting to your the incident")}...</j:jelly>

Client Script

document.location.href = "$[JS:jvar_unwrapped_url]";
