We are having the following issue with partial authorizations:
1. A user pays with a credit card
2. The card has a limit of $500 for instance.
3. The order total is $600.
4. Authorize.net charges the $500 and leaves the $100 as a remaining balance.
The intention of the user is to pay for the full amount, so the transaction should be declined.
How can we fix this?
Our environment is Magengto 2.3.1
We've used this testing guide: https://developer.authorize.net/hello_world/testing_guide.html
to generate partial authorization responses, but they have not worked.
Appreciate your help.
