When working with Webhooks, different receiving systems will treat HTML encoding differently, therefore, there should be an option for URL Macros to either be a straight text URL or an HTML encoded URL. Currently, the URL Macros (i.e. Section URL, Item URL) produce an HTML formatted link.
This was noticed from using the Slack webhook notification where it ignored the HTML encoding and then hyperlinked the URL on its own. Below is the example output received when using the Section URL Macro.
