I have the specified case with Amazon Pay.
After authorized success, I want to change the original amount of order.
Example: I create an order with amount is 2000$ to Amazon Pay. I want to change amount from 2000$ to 3000$.
I can't find any APIs in Amazon Pay to change amount after authorized.
How can I change amount of order after authorized Or Amazon APIs not support ?

I found out the way to change original amount. I will re-call Authorize with amount is not exceed 15% total amount or 75$. The link API for authorized: https://developer.amazon.com/docs/amazon-pay-api/authorize.html
