How to get notified about tax adjustments on customer charges?

[GPUSA]

Is there a flow option to be notified when a customer is charged for underestimated taxes or refunded when they paid too much tax? (This would be after they paid the initial amount)

Probably worth trying out the Order Paid trigger to see if it fires when the under/over-estimated charge/refund hits. If that doesn't work, I'd imagine the only way would be an order updated trigger, but flow doesn't support that.

I'm guessing the over/under charge will show up somewhere in the order json but not sure I've seen this before. If you want to drop an example order json in here I can take a look.
