Submitting Credit Card Transactions

Submitting Purchasing Card Transactions

Example Partial Authorization

The following is an example partial authorization.

1. You submit the initial authorization as a partial authorization.

TRXTYPE=A&TENDER=C&AMT=100.00&ACCT=4111111111111111&EXPDATE=0119

&PARTIALAUTH=Y&VERBOSITY=HIGH

2. The card issuer notes that the card has a remaining balance of $80.00.

3. The card issuer sends a partial authorization for $80.00.

RESULT=0&PNREF=VRNS1A3B33C9&RESPMSG=Partial

Approval&AUTHCODE=11111&HOSTCODE=E&PROCAVS=U&TRANSTIME=2010-04-21

11:30:45&AMT=80.00&ORIGAMT=100.00&BALAMT=0&ACCT=1111&EXPDATE=0119&IAVS=X

RESPMSG is Partial Approval, AMT is now the actual amount approved, ORIGAMT is

the original requested amount, and BALAMT is the balance on the card.

Since the amount charged is greater than the amount available on the card, the response

sets the balance amount (BALAMT) to zero. If BALAMT is zero, check if there is a balance

due by comparing the original amount to the amount charged (ORIGAMT-AMT).

4. You can choose to perform one of the following tasks:

– Accept the $80.00 and request an alternate payment from the buyer for the additional

$20.00.

– Reject the partial authorization by sending the card issuer an authorization reversal

(void) for $80.

Submitting Purchasing Card Transactions

A purchasing card (also referred to as a commercial card, corporate card, procurement card or

business card) is a credit card that an employer requests to be issued. A purchasing card is

usually reserved for business-related charges. The card issuer provides specialized reporting

for this card type so the employer can monitor the use of the card. There is no method for

determining whether a card is a purchase card or a commercial card based on the card number.

Parameter Description

PARTIALAUTH (Required) Set to Y to submit a partial authorization.

Limitations: 1 alphanumeric character.

VERBOSITY (Required) Set to HIGH to obtain information about a partial authorization in the

response.
