Converting JSON input for use in the Filemaker Server API

I have set up a node to receive api data from a system. It comes in JSON format:

   "ID": "1234567890",
   "Event":"Test Node-Red",

When it appears in Node-Red, it shows up as a string with quotes

"{"ID":"1234567890","Event":"Test Node-Red","Context":"1234567-00"}"

I want to convert this data to the following format:

{ "fieldData" : 
     "Event":"Test Node-Red",

I thought this might be as easy as using a Change Function and using a JSONata formula to change msg.payload using {"fieldData": msg.payload }

The transformation "works" but because of the quotes that were added when the data came in from the POST it doesn't work. I get:

(The screenshot references NPI instead of ID. That is because the screenshot was taken before I updated my naming)
fieldData: "
{"ID":"1234567890","Event":"Test Node-Red","Context":"1234567-00"}"

Which has the extra quotes and therefore won't work with Filemaker's API

Can someone point out a better way to do this please?



Your incoming payload from the api is a JSON string, pass it through a Json node to convert is to an object.
