Description

The syntax for using any variable in workflow payloads is not clear. There are no examples in the documentation. There are myriad issues that touch on this issue for all three approaches. Every attempt I've made to reference a variable results in nothing being added to my payload (which is a multiline YAML string formatted as JSON).

Help. This is basic stuff and the failures are exasperating.
