The reversals that made on full authorization and partial authorization are tricky to understand in one leg. Here are the differences between these two.
Full Authorization Reversal
- You did a purchase for $100, and your card balance only is $50. Then, you said you will give a check for the balance. Merchant completes partial Auth.
- After some time, you decided to cancel that and to pay the entire amount with a check. Then, the merchant reverses the $50. This is called partial Authorization reversal or full authorization reversal.
Let me put it precisely, If you paid full $100 with card, that is called full Auth. If you paid a partial amount of $50, that is called partial Auth. Here is Blog post on Tricky credit Card transactions
Partial Authorization Reversal
- Suppose, you purchased for $100, you paid with card the full amount. Just after that, the Merchant decides to give a discount of $10. To do this, Merchant will initiate partial Auth reversal.
- During the settlement time, Merchant runs partial-auth reversal transaction. The acquirer then notifies the reversed amount (Discount $10) to the card issuer. The reversed amount credits to your card.
