I've created a new leadsource and want to append it to a CMS landing page URL to tack our marketing activity - www.sitename.co.uk/landingpage?leadsource=xyz The guide here says it is possible (Lead Source parameter) https://developers.suitecommerce.com/three-essential-url-parameters-for-marketers This doesn't work on a CMS landing page. It seems to work on the home page or PDP. I have raised a support ticket but doubt this will be a priority. Anyone got this working on a CMS landing page?
