Submitting Partial Authorizations

A partial authorization is a partial approval of an authorization (TRXTYPE=A) transaction. A

partial authorization approves a transaction when the balance available is less than the amount

of the transaction. The transaction response returns the amount of the original transaction and

the amount approved.

When To Use Partial Authorizations

Use partial authorizations to reduce the number of declines resulting from buyers spending

more than their balance on prepaid cards.

Say, for example, that you sell sportswear on your website. Joe purchases a pair of running

shoes in the amount of $100.00. At checkout, Joe uses a giftcard with a balance of $80.00 to

pay. You request partial authorization of $100.00. The transaction response returns the original

amount of $100.00 and the approved amount of $80.00.

You can take either of the following actions:

 Accept the $80.00 and ask the buyer to provide an alternate payment for the additional

$20.00.

 Reject the partial authorization and submit to the card issuer an authorization reversal

(Void) for $80.00.

Required Partial Authorization Parameters

To perform a partial authorization, pass the same parameters that you would for an

authorization (TRXTYPE=A, ACCT, AMT, and EXPDATE). In addition, pass the following

parameters.
