How to add additional Request Headers in OpenAPI Integration Service

I have created an OpenAPI Integration Service (HCLCUserOrgOpenAPISerivce). I want to add some additional Request Header parameters to the operation. I can add the parameters in Request Input tab, but those additional headers are not passed in the request. When I run the operation, I see only default headers in Integration Service Input logs -

Integration Service Input -

{
    "Header": {
        "Accept": "application/json",
        "Content-Type": "application/json"
    },
    "Payload": "",
    "Method": "GET",
    "Url": "https://commerce-preview.sbx0091.play.hclsofy.com:443/wcs/resources/store/1/person/@self"
}

Is there any way to pass additional Request Header parameters to OpenAPI Integration Service ?

Hi Ashish,

Under the Request Input tab, you should see the sub tabs for Body and Header. You can click on the Header sub-tab and can add additional request header parameters.
