Where to enter these values in the Listing?

You simply pass through the data in the array being sent to the API.

width = 200
height = 200
data = {
"item_width": width,
"item_height": height,
}

You would need to login to the listing manager, select the listing you want to edit and scroll down the text input fields are half way down the page.

It may be beneficial to directly reach out to Etsy to inquire about the specifics.
