Hi, I'd like to know if it's possible to use the API t to add a row with a lookup column populated. I understand there are some limits to where and how you can use lookup columns generally (i.e. not in an Excel import template) so it might just not be possible, but on the other hand, the isheet GET endpoint does return what I assume is all the data needed to actually find the desired item.
As an example, I copied the below from the output of the GET endpoint on an item I manually populated the lookup column on; I then set it as the body of the POST call and it successfully created a row and populated the text field, but not the lookup column. I've tried several different variants of the body with no luck. Would be great to learn if it is indeed a known limitation, or if anyone's figured out any workaround.
