How to update line item discount

There are two kinds of discounts for line items:

amount

and

percentage

.

I got an error when I tried to switch the discount from

amount

to

percentage

by the update API.

The error message

“Cannot set discountPercentage without clearing discount”

How could I clear the discount for a line item? I tried to set the discount to 0 or null. But not work.

The update API that I’m using:

PATCH /crm/v3/objects/line_items/{lineItemId}

Well, I figured it out by setting the discount to ‘’. :rofl:
