Send dataset post request as JSON

For the original poster (OP) to fill in:

Introduction

We have APIs that require sending a body formatted as a JSON. Currently the field “Data to add to this request” changes the data to URl encoded characters, causing the request to fail.

User Story

guardicore, Cisco, and others require a JSON (JWT) formatted body to get a response back.

url: https://guardicore_endpoint/api/v3.0/authenticate
body:  {"username": "<username>", "password": "<password>"}
URL: https:// api.us.etd.cisco.com/v1/messages/search
body: '{"timestamp":["2023-04-01T09:34:05.361Z","2023-04-19T17:34:05.361Z"]}' 

Any chance for this to make it into the next release?
