Has anyone had success with this? The requirement to have input data wrap the JSON seems to be causing error

I am trying to send an Post to Manage engine Service desk. I have a data connector that is linked to the on prem server hosting the site. I can use Postman and Post/ add a ticket successfully. But when I try replicating what I’m doing in postman with the connector in Power automate it fails.

Heres what I know. Postman is wrapping its JSON with "input\_data:" 

    'input_data={

      "request": {

        "subject": "New Vulnerability Detected",

        "description": "Details of the vulnerability...",

        "template": {

          "name": "Vulnerability Remediation"

        },

        "requester": {

          "name": "Automated System"

        },

In Postman it allows me to set a "key" (Input\_data) with the json data as the value. Thats why it formats correctly. Postman is using application/x-www-form-urlencoded.

 but theres just no way to do that from what I can tell when creating a connector. Ive tried a stringified JSON object and pretty much every version of sending the request but the response is never wrapped correctly. I DONT GET IT. Why is it working in postman and not in the connector. I KNOW the connector can call to the server because I can run GET requests fine. 

ITS THAT DUMB INPUT\_DATA PART. maybe its a swagger limitation or somethin idk man. Or maybe manage engine techs can help me solve this one. Thank you!!
