Posting to api using object data found in payload from network tab

I am brand new to using data found in my network tab. I am posting to an api leveraging data found in the payload. What i want to know is, if my form data payload object looks like this

 description$id: J2l_1_194_350
description$html: <p>my text here</p>
description$htmlOrgUnitId: eijlfld

How do i write that in an object? For instance seems like using "description$html" is incorrect. What is the right way to write that?
