Copy/Paste math.js expression?

I’m using the API Connector(old) to make a post to math.js to perform a calculation based on dynamically pulled data. I have to recreate this many times and there are a lot of values at play. Is there a way to insert dynamic data into the body of the api post under the “Plugins” tab?

I see text that reads (JSON object, use ___ for dynamic values) but I don’t know what the symbol in the blank space is.

Any help?

And now I’m realizing my new api connector won’t intialize. I receive an error that says “Internal server error”. Everything is set up exactly as it is in the old api connector…

Take a look at this https://forumapp3.bubbleapps.io/version-test/math_js?debug_mode=true. The “Calculate New API” button is using the new API connector.

Here’s the setup for the connector.
