I’m unable to find amount that was captured after the authorization.
Also when I cancel the order and refund partially, then too I do not get the amount that was refunded.
In [Orders API][1] of this transactions I only find is net amount, Shipping amt, Tax amt, Discount amt of the product, But no where I can see Captured amount or Refunded amount
Is there any way I can get the Captured amount or Refunded amount using API?
Take a look at the Transactions API for that kind of information.
