## Authorization transaction [#authorization-transaction]
An authorization transaction places a hold on the cardholder's available fund limit, lowering the cardholder's limit by the amount of the transaction. An authorization transaction *does not* transfer funds.
### Request [#request]
To perform an authorization, pass the `TRXTYPE=A` parameter along with the required connection, user, and [credit card transaction](/api/nvp-soap/payflow/integration-guide/submit-transactions/#core-credit-card-parameters) parameters to the appropriate endpoint.
```text lineNumbers
USER=XXXXXX&VENDOR=XXXXXXXX&PARTNER=PayPal&PWD=XXXX&TRXTYPE=A&TENDER=C&ACCT=4xxxx&EXPDATE=xxxx&CVV2=xxx&AMT=1.00&INVNUM=521aa62355f5eb5515eca3777e1f8b78&PONUM=PFDCCTEST&COMMENT1=Test Comment 1&COMMENT2=Test Comment2&VERBOSITY=HIGH&BILLTOFIRSTNAME=Frank
&BILLTOLASTNAME=Enstien&BILLTOSTREET=123 Main St.&BILLTOSTREET2=Suite 267&BILLTOCITY=GILBERT
&BILLTOSTATE=AZ&BILLTOZIP=85298&INVNUM=InvoiceNumber001&CUSTOM=CustomNumber001
```
### Response [#response]
```text lineNumbers
RESULT=0&PNREF=B10P4FFEB1AD&RESPMSG=Approved&AUTHCODE=111111&AVSADDR=Y&AVSZIP=Y&CVV2MATCH=Y&PPREF=28X110156B855103Y&CORRELATIONID=8460f71a9c548&PROCAVS=X&PROCCVV2=M&TRANSTIME=2013-08-1310:03:54&BILLTOFIRSTNAME=Frank&BILLTOLASTNAME=Einstein&AMT=1.00&ACCT=7271&EXPDATE=1220&CARDTYPE=0&IAVS=N&PREFPSMSG=NoRulesTriggered&POSTFPSMSG=No Rules Triggered
```
> **Note:** **Note:** For authorization and sale transactions, the `INVNUM` and `CUSTOM` parameters send unique identifiers for each transaction. If PayPal is your payments processor, these are displayed in your PayPal reports. You can also include the `COMMENT1` and `COMMENT2` parameters to append useful information for each transaction.
## Delayed capture transaction [#delayed-capture-transaction]
Perform a delayed capture transaction after an authorization transaction to capture the authorization amount to be collected during the net settlement period.
### Request [#request-1]
To perform a delayed capture, pass `TRXTYPE=D` and `ORIGID` (the ID of the original transaction referenced) along with the required connection, user, and [credit card transaction](/api/nvp-soap/payflow/integration-guide/submit-transactions/#core-credit-card-parameters) parameters to the appropriate endpoint.
Optionally, if you process payments through PayPal, you can include the `CAPTURECOMPLETE` parameter. This indicates whether the delayed capture transaction is the last capture you intend to make. Valid values are `Y` (default) or `N`. If `CAPTURECOMPLETE=Y` is passed, any remaining amount of the original reauthorized transaction is automatically released.
```text lineNumbers
USER=XXXXXX&VENDOR=XXXXXXXX&PARTNER=PayPal&PWD=XXXX&TRXTYPE=D&TENDER=C&AMT=1.00&ORIGID=B10P4FFEB1AD&CAPTURECOMPLETE=Y&VERBOSITY=HIGH
```
### Response [#response-1]
The `PNREF` parameter returns the `ORIGID`.
```text lineNumbers
RESULT=0&PNREF=A71AA1A79003&RESPMSG=Approved&AUTHCODE=527PNI&AVSADDR=Y&AVSZIP=Y
&CVV2MATCH=Y
```
## Sale transactions [#sale-transactions]
Sale transactions charge the specified amount against the account and marks the transaction for immediate fund transfer during the next settlement period.
> **Note:** **Note:** If you signed up for the Fraud Protection Services you need to leverage authorization `TRXTYPE=A`, delay capture `TRXTYPE=D` type transactions instead of a sale `TRXTYPE=S` to avoid charging the card if FPS declines it.
### Request [#request-2]
To perform a sale transaction, pass the `TRXTYPE=S` parameter along with the required connection, user, and [credit card transaction](/api/nvp-soap/payflow/integration-guide/submit-transactions/#core-credit-card-parameters) parameters to the appropriate endpoint.
```text lineNumbers
USER=XXXXXX&VENDOR=XXXXXXXX&PARTNER=PayPal&PWD=XXXX&TRXTYPE=S&TENDER=C&ACCT=4xxxx&EXPDATE=xxxx&CVV2=xxx&AMT=1.00&INVNUM=521aa62355f5eb5515eca3777e1f8b78&PONUM=PFDCCTEST&COMMENT1=Test Comment 1&COMMENT2=Test Comment2&VERBOSITY=HIGH&BILLTOFIRSTNAME=Frank
&BILLTOLASTNAME=Enstien&BILLTOSTREET=123 Main St.&BILLTOSTREET2=Suite 267&BILLTOCITY=GILBERT
&BILLTOSTATE=AZ&BILLTOZIP=85298&INVNUM=InvoiceNumber001&CUSTOM=CustomNumber001
```
### Response [#response-2]
```text lineNumbers

&CVV2MATCH=Y&PPREF=28X110156B855103Y&CORRELATIONID=8460f71a9c548& PROCAVS=X

&AMT=1.00&ACCT=7271&EXPDATE=1220&CARDTYPE=0&IAVS=N& PREFPSMSG=No Rules Triggered
&POSTFPSMSG=No Rules Triggered
```
## Void transaction [#void-transaction]
A void transaction prevents the capture of authorized funds from being settled. You can only void transactions that have not yet settled.
### Request [#request-3]
To perform a void transaction, pass the `TRXTYPE=V` and `ORIGID` parameters along with the required connection, user, and [credit card transaction](/api/nvp-soap/payflow/integration-guide/submit-transactions/#core-credit-card-parameters) parameters to the appropriate endpoint.
```text lineNumbers
USER=XXXXXX&VENDOR=XXXXXXXX&PARTNER=PayPal&PWD=XXXX&TRXTYPE=V&TENDER=C
&AMT=1.00&ORIGID=B10P4FFEB1AD&CAPTURECOMPLETE=Y&VERBOSITY=HIGH
```
### Response [#response-3]
```text lineNumbers
RESULT= 0&PNREF= B70P4EBC54B7&RESPMSG= Approved&PPREF= 5GY89824G17878310&
CORRELATIONID= fde19f9e30d73
```
## Credit or refund transaction [#credit-or-refund-transaction]
Credit or refund transactions refund a specified amount back to the cardholder.
### Request [#request-4]
To perform a credit or refund transaction, pass the `TRXTYPE=C` and `ORIGID` parameters along with the required connection and user parameters. To refund an amount that is less than the amount that was originally charged, specify the `AMT` parameter.
```text lineNumbers
USER=XXXXXX&VENDOR=XXXXXXXX&PARTNER=PayPal&PWD=XXXX&TRXTYPE=C&TENDER=C&AMT=1.00&ORIGID=B1PP4FFEBD85&VERBOSITY=HIGH
```
### Response [#response-4]
