int CreditCardProcessor::authorize	(	const int	pccardid,
		const QString &	pcvv,
		const double	pamount,
		double	ptax,
		bool	ptaxexempt,
		double	pfreight,
		double	pduty,
		const int	pcurrid,
		QString &	pneworder,
		QString &	preforder,
		int &	pccpayid,
		QString	preftype,
		int &	prefid
	)

virtualinherited

Processes pre-authorization transactions.

This method performs application-level error checking and all of the database work required to handle a pre-authorization transaction. It calls doAuthorize to handle the direct communication with the service.

Warning: This method should never be overridden. Service-specific functionality should be implemented in the doAuthorize method of the service' subclass.

Parameters

[in]	pccardid	The internal id of the credit card to preauthorize
[in]	pcvv	The CVV/CCV code of the credit card to preauthorize
[in]	pamount	The total amount to preauthorize. If the credit card processor does not preauthorize the full amount requested, the database will store the actual amount that was authorized If this occurs, the application will display an error if the amount authorized is 0 or a warning if the amount authorized is greater than 0.
[in]	ptax	The subportion of the total which is tax
[in]	ptaxexempt	Whether or not this transaction is tax exempt
[in]	pfreight	The subportion of the total which is freight
[in]	pduty	The subportion of the total which is customs duty
[in]	pcurrid	The currency of the amount to preauthorize
[in,out]	pneworder	The order number associated with this preauthorization
[out]	preforder	The reference number associated with this preauthorization (may be required to 'capture' the preauthorization)
[out]	pccpayid	The ccpay_id of the record created by this transaction
[in]	preftype	Either `cohead` or `cashrcpt` or blank
[in,out]	prefid	The cashrcpt_id or cohead_id associated with this transaction

Returns: An index into _errMsg; 0 indicates success

ParameterList CreditCardProcessor::authorize ( const ParameterList & pinput )

staticinherited

Processes pre-authorization transactions.

This version of authorize is intended for use by scripts. Instead of passing all of the arguments in order, this method allows creating a QtScript object and setting properties on this object by name. Then the script can pass this object to authorize(const int pccardid, const int pcvv, const double pamount, double ptax, bool ptaxexempt, double pfreight, double pduty, const int pcurrid, QString &pneworder, QString &preforder, int &pccpayid, QString preftype, int &prefid):

var params = new Object;
params.ccard_id = _ccardid;
params.cvv      = _cvv.text;
...
var processor = toolbox.getProcessor();
var result = processor.authorize(params);
if (result.returnVal < 0)
  // handle errors
else if (result.returnVal > 0)
  // handle warnings
...

Parameters

pinput The parameter list to unpack and use to call authorize

Returns: A parameter list containing the output parameters, plus one called returnVal holding the return value of authorize

protectedvirtualinherited

QString CreditCardProcessor::buildURL	(	const QString	pserver,
		const QString	pport,
		const bool	pinclport
	)

protectedvirtualinherited

Construct a valid URL from the information in the configuration.

Handle the case where someone leaves off a piece of the URL when entering the basic configuration. Note that a lot of people are used to typing in web browsers, which fill in some parts for them.

If the user did not enter values for the server or the port on the configuration, use the defaults provided by the service' subclass.

Parameters

pserver	Use this server, or the defaultServer if blank
pport	Use this port, or the defaultPort if blank
pinclport	Flag whether the port should be part of the constructed URL or not

See also: defaultServer; defaultPort

		QString &	pneworder,
		QString &	preforder,
		int &	pccpayid,
		QString	preftype,
		int &	prefid
	)

virtualinherited

Processes charge transactions.

This method performs application-level error checking and all of the database work required to handle a credit card charge transaction. It calls doCharge to handle the direct communication with the service.

[in]	ptaxexempt	Whether or not this transaction is tax exempt
[in]	pfreight	The subportion of the total which is freight
[in]	pduty	The subportion of the total which is customs duty
[in]	pcurrid	The currency of the amount to charge
[in,out]	pneworder	The order number associated with this charge
[out]	preforder	The reference number associated with this charge
[out]	pccpayid	The ccpay_id of the record created by this transaction
[in]	preftype	Either `cohead` or `cashrcpt` or blank
[in,out]	prefid	The cashrcpt_id or cohead_id associated with this transaction

Returns: An index into _errMsg; 0 indicates success

ParameterList CreditCardProcessor::charge ( const ParameterList & pinput )

staticinherited

Processes charge transactions.

This version of charge is intended for use by scripts. Instead of passing all of the arguments in order, this method allows creating a QtScript object and setting properties on this object by name. Then the script can pass this object to charge.

Parameters

pinput The parameter list to unpack and use to call charge

Returns: A parameter list containing the output parameters, plus one called returnVal holding the return value of charge

See also: authorize(const ParameterList &pinput)

		const double	pamount,
		const int	pcurrid,
		QString &	pneworder,
		QString &	preforder,
		int &	pccpayid
	)

virtualinherited

Processes 'capture' transactions, or charges against a prior preauthorization.

This method performs application-level error checking and all of the database work required to 'capture' or complete the charge against a prior preauthorization. It calls doChargePreauthorized to handle the direct communication with the service.

Warning: This method should never be overridden. Service-specific functionality should be implemented in the doChargePreauthorized method of the service' subclass.

Parameters

[in]	pcvv	The CVV/CCV code of the credit card to charge
[in]	pamount	The total amount to charge
[in]	pcurrid	The currency of the amount to charge

[in,out]	preforder	The reference number (preforder) generated by the preauthorization transaction
[in,out]	pccpayid	When calling the method, pccpayid should be the ccpay_id of the preauthorization record. On return, this is the ccpay_id of the charge record, which may be the same as the preauthorization record.

Returns: An index into _errMsg; 0 indicates success

ParameterList CreditCardProcessor::chargePreauthorized ( const ParameterList & pinput )

staticinherited

Captures preauthorized transactions.

This version of chargePreauthorized is intended for use by scripts. Instead of passing all of the arguments in order, this method allows creating a QtScript object and setting properties on this object by name. Then the script can pass this object to chargePreauthorized.

Parameters

pinput The parameter list to unpack and use to call chargePreauthorized

Returns: A parameter list containing the output parameters, plus one called returnVal holding the return value of chargePreauthorized

See also: authorize(const ParameterList &pinput)

int CreditCardProcessor::checkCreditCard	(	const int	pccid,
		const QString &	pcvv,
		QString &	pccard_x
	)

protectedvirtualinherited

Check if the given credit card is consistent and active.

This consistency check is used in a number of places before executing a credit card transaction. It confirms that the given card is marked as active in the system and has not expired. If the card has expired based on the expiration month and year, then it is marked as expired in the database. It also makes sure that the CVV has been entered if the system is configured to require it.

Parameters

	pccid	The ccard_id of the credit card to check
	pcvv	The CVV from the card holder, -1 if not known, -2 if the caller knows it is not required or available (such as for void transactions).
[out]	pccard_x	The credit card number, with most of the digits replaced with `X`. Used for reporting errors.

Returns: An index into _errMsg; 0 indicates success

ParameterList CreditCardProcessor::credit ( const ParameterList & pinput )

staticinherited

Processes credit transactions.

This version of credit is intended for use by scripts. Instead of passing all of the arguments in order, this method allows creating a QtScript object and setting properties on this object by name. Then the script can pass this object to credit.

Parameters

pinput The parameter list to unpack and use to call credit

Returns: A parameter list containing the output parameters, plus one called returnVal holding the return value of credit

This is slightly different than the version in the CurrDisplay widget because credit card processing has special error reporting needs.

Parameters

	pfrom	The source currency
	pto	The destination currency
	pamount	The value of the transaction in the source currency
[out]	perror	The CreditCardProcessor error code for a failed conversion
