Need Help Configuring payload for HTTP request

Having difficulty getting the payload correct for an HTTP / RESTAPI call. I first develop using POSTMAN (just find it easier) and then transfer to Node-Red, either in function node or change node. I can't get the following to convert over. Below is the curl that works fine. Help and suggestions greatly appreciated. Thank you.
curl --location --request POST 'http://ec????????.compute-1.amazonaws.com//restapi/v1/vtews/update' \

--header 'Content-Type: application/json' \

--header 'Authorization: Basic ??????????????????' \

--data-raw '{

"id": "3x55",

"columns": "{\"cf_1095\":\"True\"}"

}'
