The response to your question is in your screenshot, your contents parameter is missing content_id key, here’s the description of that param:

I don’t understand your comment, you add item id variable where? If you want to get some help - please outline the situation in full, add some screenshots - anything to work with.

Bottom line is your contents object must be structured as the documentation requires. Your error stems from the fact you’re not sending correct payload.
