In UCCE 12.6 I am trying to pass a custom payload using Dialogflow.queryParams.payload vxml property for dialogflow element. But the payload does not show up on the google dialogflow side. In fact any other properties like geoloction, timezone are not showing up in the dialogflow request. I tried setting those properties in root doc as well as element level.
Thanks for the reply. Yes I saw this guide but it doesn't have any reference to vxml properties as such. Also I have verified that we are on latest versions 12.6.1 w/latest ESs for all of our components.
