Help expressing a value in Json?

General
1

This is an existing issue, I don't think I'm asking the question properly.

I have no issue capturing the data or sending data to my controller. My issue is I cant seam to figure out how to send my captured date (payload) to my output string. what i need to automate is the changing of the "value"

The string I send to my controller is

Json

What ever I set in "value": "X" presently ( "value": "85"), get written no issues.

how do i make this my payload value?

The quick way is to change the 5 to say msg.payload, then change the type of the field in the Change node rule to be Expression rather than JSON

What you have shown is static JSON. You need something dynamic. You have a number of choices.

One way would be to use the JSONata feature instead of plain JSON. That would let you substitute payload as a property instead of your fixed "85" string.

Another way would be to have 2 changes in your change node. The first to create the JSON and the second to set msg.payload.propertyReferences[0].value to `payload1.

UPDATE: My first example is what Nick just described.
