I am trying to make a REST service call using POST method from Avaya OD's REST editor and want to know how to set the request parameters in json format. When adding each value using input parameters option, that data is going as part of URL. I want the input request to be part of the body in json format.
This is the first time I am trying REST service in OD, can you please help me with this issue? If possible can you please send a screenshot of an example where you pass request parameters in json format.
Thank you.

Here is an example screen attached.

Any way to use session variables in message body ?

EDIT: I figured it out:

JSON{"someVar": "someStaticValue","someVar1": "_{sessionVariableName}_"}

It schould be placed in developers guide.
