I know I can set variable in script and use it in body. but I don’t want to save the variable, I want to use “return”, this works in similar tools.

example of what I want to achieve :

**pre-request script :**  
return “hello from script”

**request body :**  
{“message” : {{\*\*\*}}

is it possible? what there should be instead of \*\*\*

The intended way is to use variables. If you really don’t like them being saved, you can always use `pm.variables.set("var", "hello from script");` so they don’t show up in your collection or environment and will be deleted after the request has finished running. Then your request’s body can be `{ "message" : {{var}} }`.
