Updating Values Via POST Method in JSON


I am trying to create a flow that will send back an Update to IoT sensors that are used to monitor fuel levels. Once an Customer Asset record is updated, in this case a Name, I would like to call a POST Method that will Post to the specific ID (in the URL) and update the value from the Customer Asset to the API (server side). I was using the "Concat" expressions but with no luck. I should mention the field data type on the Customer Asset is a "Single Line Text", this needs to be converted to JSON format in order to be sent.
