📝 Describe your problem

I would like to add a dynamic value in the body request.
I know it's possible to check the response with JSONata, I need something similar to create a dynamic JSON/XML body with the current timestamp. For instance:

{
  "parameter": $now()
}

Reassigned as feature-request instead of a help issue.

Unsure how to implement this

• without being too bad for maintenance
• without being backwards-breaking

We can basically group this together with #4383 by providing a template language (liquid.js) for the request body input.

Agree, merging into #4383 and making said issue a bit more generic.
