PTechECommerce Class

Properties   Methods   Events   Config Settings   Errors  

The PTECHECOMMERCE class is an advanced tool used to authorize credit card transactions in both Direct Marketing and E-Commerce environments with the Paymentech NetConnect system on the Tampa platform. It allows for simple, direct, secure communication to the Paymentech TLS/SSL gateway through a standard Internet connection. This class can be integrated into web pages or stand-alone Point Of Sale applications. Because all TLS/SSL communications are handled inside the class, any application or web page can be deployed without the need for expensive dedicated TLS/SSL servers.

Syntax

class dpaymentssdk.PTechECommerce

Remarks

Setting up the class and authorizing a transaction is easy. First, set the merchant_number, terminal_number, client_number, user_id, and password with the information given to you when you signed up for Paymentech service. You should also set your industry_type to either Direct Marketing (mail order/telephone order) or E-Commerce at this time.

After the merchant information is setup, you may enter transaction data. The Credit Card's card_entry_data_source must be Manually Entered for this class, so the card_number, card_exp_month, and card_exp_year properties should be filled out and the card_magnetic_stripe left empty. Address Verification Service (AVS) data may be sent by filling the customer_address and customer_zip properties. In addition, the transaction_amount should be set with the total amount for the transaction, including any taxes.

Now simply call the sale or auth_only method to send the authorization to the Paymentech server.

The status of the authorization request will be stored in the response_code property, with human-readable text appearing in the response_text property. There are several other Response properties which will contain data that should be logged.

Once an authorization request is approved, one of three things happen. If you are using the Host Capture settlement_mode, and your Paymentech account is setup with the Host Auto Close feature, you need take no further action. The host will close the current open batch at a designated time each day. This means that there is no end of day batch processing required from the merchant. In order for the merchant's batch to be included in the Paymentech Host Auto Close process, the merchant parameter file on the host must indicate that the merchant is Auto Close. Without this flag being set, the merchant's transactions must be settled with a Manual Batch Release.

If you are using the Host Capture settlement_mode, and your Paymentech account not setup with Host Auto Close, then after an authorization is approved the transaction is added to the current batch on the Paymentech server, and the money in the customer's account is blocked and tagged for the merchant. The transaction must go through the Manual Batch Release Settlement process in order for the blocked money to be transferred to the merchant's account. To release a batch for settlement, please see the PTechHostSettle class.

If you are using the Terminal Capture settlement_mode, you must store the XML aggregate returned from the get_detail_aggregate method and submit it at the end of the day in a manual batch settlement. A detail aggregate for each authorized transaction must be sent in a batch using the PTechManualSettle class. A transaction that has been authorized and then subsequently voided with this class must NOT be added to the batch settlement, and must not be submitted with the PTechManualSettle class. Any transaction not submitted with PTechManualSettle will eventually time out, and the block on the customer's card will be removed (essentially, you may void transactions by simply not sending them in the batch settlement). The Terminal Capture settlement_mode is required for the Restaurant and Hotel industry_types. This is because both industry_types will generally have additional charges added on to the original authorization (for example: a tip for your server, or a drink from the hotel bar charged to your room). Other industry_types may benefit from this functionality as well, but if you do not require your transactions to be authorized for one amount and then settled for a different amount, it is highly recommended you use the much simpler Host Capture settlement_mode.

Note that a transaction authorized in the Host Capture settlement_mode MUST be released for settlement using the PTechHostSettle class. It cannot be added to a manual batch settlement using the PTechManualSettle class. Doing so will result in charging the customer twice! Likewise, transactions authorized with settlement_mode set to Terminal Capture cannot be released using the PTechHostSettle class, because no record of the transaction has been stored on the Paymentech server.

Also note that you cannot mix Host Capture and Terminal Capture settlement_modes on the same merchant_number / terminal_number pair. Contact Paymentech to setup your merchant account for Terminal Capture.

Default Value

FALSE

Remarks

Determines whether data set to the card_number or card_magnetic_stripe fields is validated.

By default, when the card_number or card_magnetic_stripe fields are set, the value will be validated and normalized. For instance, "4444-33332222 1111" will be normalized as "4444333322221111" and card_magnetic_stripe data will be parsed for the track specified by card_entry_data_source. However, any other non-numerical data entered will cause an exception to be thrown. It may be useful in some gateways to send other data in the card_number or card_magnetic_stripe fields, and this can be accomplished by setting IsEncrypted to true. However, please note that in doing so automatic calculation of the card_type may be affected, and the card number will not be verified.

card_magnetic_stripe Property

This includes everything after but not including the start sentinel (% or ;) and up to but not including the end sentinel (?) and LRC check character. You may only set this property with track 1 or track 2 data, and may not pass both. Use the card_entry_data_source property to indicate which track you are sending.

The following example shows how to set the card_magnetic_stripe and card_entry_data_source properties if the data read off the card is "%B4788250000028291^TSYS^05121015432112345678?;4788250000028291=05121015432112345678?"

class.CardMagneticStripe = "B4788250000028291^TSYS^05121015432112345678" class.CardEntryDataSource = edsTrack1 or class.CardMagneticStripe = "4788250000028291=05121015432112345678" class.CardEntryDataSource = edsTrack2

The ssl_cert_store_type property denotes the type of the certificate store specified by ssl_cert_store. If the store is password protected, specify the password in ssl_cert_store_password.

ssl_cert_store is used in conjunction with the ssl_cert_subject property to specify client certificates. If ssl_cert_store has a value, and ssl_cert_subject or ssl_cert_encoded is set, a search for a certificate is initiated. Please see the ssl_cert_subject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

ssl_cert_store_password Property

If the type of certificate store requires a password, this property is used to specify the password needed to open the certificate store.

Syntax

def get_ssl_cert_store_password() -> str: ...
def set_ssl_cert_store_password(value: str) -> None: ...

ssl_cert_store_password = property(get_ssl_cert_store_password, set_ssl_cert_store_password)

Syntax

def get_ssl_cert_subject() -> str: ...
def set_ssl_cert_subject(value: str) -> None: ...

ssl_cert_subject = property(get_ssl_cert_subject, set_ssl_cert_subject)

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

def set_ssl_provider(value: int) -> None: ...

ssl_provider = property(get_ssl_provider, set_ssl_provider)

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the class will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The class will select a provider depending on the current platform.

When Automatic is selected, on Windows the class will use the platform implementation. On Linux/macOS the class will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

ssl_server_cert_encoded Property

This is the certificate (PEM/Base64 encoded).

Syntax

def get_ssl_server_cert_encoded() -> bytes: ...

ssl_server_cert_encoded = property(get_ssl_server_cert_encoded, None)

timeout Property

A timeout for the class.

Syntax

def get_timeout() -> int: ...
def set_timeout(value: int) -> None: ...

timeout = property(get_timeout, set_timeout)

Default Value

60

Remarks

If the timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use do_events to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not "freeze" and remains responsive.

If timeout expires, and the operation is not yet complete, the class fails with an error.

Please note that by default, all timeouts are inactivity timeouts, i.e. the timeout period is extended by timeout seconds when any amount of data is successfully sent or received.

The default value for the timeout property is 60 seconds.

transaction_amount Property

Purchase amount for an authorization.

Syntax

def get_transaction_amount() -> str: ...
def set_transaction_amount(value: str) -> None: ...

transaction_amount = property(get_transaction_amount, set_transaction_amount)

Default Value

""

Remarks

This field contains the transaction amount to be authorized. The transaction amount is presented in US Dollars with a decimal point in the proper position. If sending a Debit transaction and the customer requests cash back, the transaction_amount must include the total cost of the purchase, PLUS the debit_cash_back amount.

This must be formatted as a dollar amount with a real decimal point, excluding the dollar sign. For instance "12.00"

user_id Property

def get_user_id() -> str: ...
def set_user_id(value: str) -> None: ...

user_id = property(get_user_id, set_user_id)

Default Value

""

Remarks

The user_id will be supplied to you by PaymenTech.

xid Property

TransactionId from a 3D Secure authentication.

Syntax

def get_xid() -> str: ...
def set_xid(value: str) -> None: ...

xid = property(get_xid, set_xid)

Default Value

""

Remarks

This property is used to pass the 3D Secure TransactionId (XID) data on to the credit card processor. This property must be a 40-byte plaintext value, or a 28-byte Base-64 encoded value. This class may be used in conjunction with the IP*Works! 3D Secure MPI class or with any other 3D Secure MPI implementation. For example:

class.XID = ThreeDSecure.TransactionId

Other properties necessary for passing 3D Secure data are cavv and eci.

auth_only Method

Sends an AuthOnly transaction to the host.

Syntax

def auth_only() -> None: ...

Remarks

An Auth Only transaction is used to verify and reserve the cardholder's open-to-buy funds available at that time. This transaction is NOT added to the open batch. In order to settle (be paid) for this transaction, the merchant must run a capture transaction using the original response_approval_code obtained during this Auth Only transaction. This will add the transaction to the batch. The funds may then be captured by settling the batch with the batch_release method. Typically any funds blocked with a Sale or Auth Only transaction are reserved for approximately seven (7) to ten (10) days. This may vary from issuer to issuer. Sample transactions follow.

E-Commerce AuthOnly transaction: class.IndustryType = itECommerce class.CardEntryDataSource = dsManuallyEntered class.GoodsIndicator = giPhysicalGoods class.CardNumber = "4444333322221111" class.CardExpMonth = 1 class.CardExpYear = 2010 class.CustomerAddress = "123 Nowhere Ln." ' optional AVS data class.CustomerZip = "90210" ' optional AVS data class.TransactionAmount = "1.00" class.InvoiceNumber = "1234" class.AuthOnly()

Retail AuthOnly transaction: class.IndustryType = itRetail class.CardEntryDataSource = dsTrack1 class.CardMagneticStripe = "B4788250000028291^PAYMENTECH^05121015432112345678" class.TransactionAmount = "1.00" class.AuthOnly()

Retail manually keyed AuthOnly transaction: class.IndustryType = itRetail class.CardEntryDataSource = dsManuallyEntered class.CardNumber = "4444333322221111" class.CardExpMonth = 1 class.CardExpYear = 2010 class.TransactionAmount = "1.00" class.AuthOnly()

capture Method

Sends a capture transaction to the PaymenTech Server.

Syntax

def capture(approval_code: str) -> None: ...

Remarks

Capture (Prior Sales) are typically used when a merchant has previously utilized the auth_only method. A Capture transaction adds the transaction to the current open batch, and the transaction will be settled at the next call to the PTechHostSettle class's BatchRelease method. The Paymentech system treats Capture and Force transactions identically, so this method may also be used when a merchant has obtained voice approval over the phone.

Manually keyed capture: class.CardNumber = "4444333322221111" class.CardExpMonth = 1 class.CardExpYear = 2010 class.TransactionAmount = "1.00" class.Capture("123456") 'value from voice auth or previous AuthOnly trans

Note: This method is not available when using the Terminal Capture settlement_mode.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

credit Method

Credits a cardholder's account or obtains a Return Authorization.

Syntax

def credit() -> None: ...

Remarks

Also known as a Return, this transaction refunds the cardholder's account. It can be used in both Host Capture and Terminal Capture settlement_modes.

If you are using the Host Capture settlement_mode, the credit method will send a Return request to Paymentech. Paymentech will treat the request as an online purchase return authorization if the online return functionality is available for the given card brand and merchant. In this case an authorization request is sent to the card brand and if the authorization is successful the transaction is automatically included in the current batch for settlement. If that functionality is not available the request will be handled as an off-line credit request and will be included in the batch for settlement without requesting an authorization first.

If you are using the Terminal Capture settlement_mode, the credit method can only be used for online purchase return authorization requests when such functionality is available for the given card and merchant. It cannot be used for off-line credit transactions. When using the credit method in Terminal Capture mode you will need to get the authorization response and include the transaction in the batch to be settled using the PTechManualSettle class.

Manually keyed credit: class.CardNumber = "4444333322221111" class.CardExpMonth = 12 class.CardExpYear = 2025 class.CardEntryDataSource = dsManuallyEntered class.TransactionAmount = "1.00" 'credits $1.00 class.Credit()

get_detail_aggregate Method

Returns an aggregate containing details of this transaction, which is then used for manual settlement.

Syntax

def get_detail_aggregate() -> str: ...

Remarks

This method returns an aggregate containing all of the required data to send a transaction to settlement. This is only used when processing on the Terminal Capture System (TCS) and using the PTechManualSettle class Generally, you will only use detail aggregates and manual settlements for the Hotel and Restaurant industry_types.

This aggregate must be passed to the PTechManualSettle class's DetailRecords array property in order to settle the transaction. If you wish to view or change any part of the aggregate (such as adding a gratuity or extra hotel charges for instance), you may use the PTechDetailRecord class to do so.

Note: This method may only be called after a successful authorization. If the authorization was not successful the method fails with an error.

An example of how this method is used is shown below:

PTechCharge.Sale(); PTechManualSettle.DetailRecords[0] = PTechCharge.GetDetailAggregate();

interrupt Method

Interrupt the current method.

Syntax

def interrupt() -> None: ...

Remarks

If there is no method in progress, interrupt simply returns, doing nothing.

reset Method

Clears all properties to their default values.

Syntax

def reset() -> None: ...

Remarks

This method clears all properties to their default values.

sale Method

Sends a Sale transaction to the host.

Syntax

def sale() -> None: ...

Remarks

A basic sale transaction. This transaction decrements the cardholder's open-to-buy funds for the sale amount. This transaction is automatically added to the current open batch, and will be settled after the current batch is released with the PTechHostSettle class. Sample transactions follow.

E-Commerce Sale transaction: class.IndustryType = itECommerce class.GoodsIndicator = giPhysicalGoods class.CardEntryDataSource = dsManuallyEntered class.CardNumber = "4444333322221111" class.CardExpMonth = 1 class.CardExpYear = 2010 class.CustomerAddress = "123 Nowhere Ln." ' optional AVS data class.CustomerZip = "90210" ' optional AVS data class.TransactionAmount = "1.00" class.Sale()

Retail Sale transaction: class.IndustryType = itRetail class.CardEntryDataSource = dsTrack1 class.CardMagneticStripe = "B4788250000028291^PAYMENTECH^05121015432112345678" class.TransactionAmount = "1.00" class.Sale()

Retail manually keyed Sale transaction: class.IndustryType = itRetail class.CardEntryDataSource = dsManuallyEntered class.CardNumber = "4444333322221111" class.CardExpMonth = 1 class.CardExpYear = 2010 class.TransactionAmount = "1.00" class.Sale()

void_transaction Method

Voids a transaction in the current batch.

Syntax

def void_transaction(retrieval_number_to_void: str, last_retrieval_number: str) -> None: ...

Remarks

This method voids a previously authorized transaction. A transaction can only be voided if it exists in the current open batch. If the batch that contained the target transaction has already been released (settled), you must use the credit method instead.

The void_transaction method has two parameters, RetrievalNumberToVoid and LastRetrievalNumber. RetrievalNumberToVoid is the response_retrieval_number of the transaction you wish to void. LastRetrievalNumber should be set to the last response_retrieval_number received from the Paymentech server. If LastRetrievalNumber is left blank, the current contents of the response_retrieval_number property will be used instead.

Before sending a void, you must make sure that the card_number property contains the card number from the original transaction. Also note that since AuthOnly transactions are not added to the current batch, they cannot be voided. Examples follow.

class.CardNumber = "4444333322221111" class.CardExpMonth = 1 class.CardExpYear = 2010 class.TransactionAmount = "1.00" class.Sale() cnumToVoid = class.CardNumber refNumToVoid = class.ResponseRetrievalNumber ... more sale transactions ... 'All that's needed for a void: class.CardNumber = cnumToVoid class.VoidTransaction(refNumToVoid, "")

Note that in the above void, if you use a new instance of the class or otherwise reset it's state, you must set the LastRetrievalNumber parameter as well.

Note: This method is not available when using the Terminal Capture settlement_mode.

on_data_packet_in Event

Fired when receiving a data packet from the transaction server.

Syntax

class PTechECommerceDataPacketInEventParams(object):

@on_data_packet_in.setter
def on_data_packet_in(event_hook: Callable[[PTechECommerceDataPacketInEventParams], None]) -> None: ...

Remarks

This event fires when a packet is received. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting, or to extract additional response properties beyond the scope of this class.

on_data_packet_out Event

Fired when sending a data packet to the transaction server.

Syntax

class PTechECommerceDataPacketOutEventParams(object):
  @property
  def data_packet() -> bytes: ...

# In class PTechECommerce:
@property
def on_data_packet_out() -> Callable[[PTechECommerceDataPacketOutEventParams], None]: ...
@on_data_packet_out.setter
def on_data_packet_out(event_hook: Callable[[PTechECommerceDataPacketOutEventParams], None]) -> None: ...

Remarks

This event fires right before each data packet is sent. The entire data packet (including all framing and error detection characters) is contained in the parameter "DataPacket". This parameter may be inspected for advanced troubleshooting.

on_error Event

Information about errors during data delivery.

Syntax

class PTechECommerceErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class PTechECommerce:
@property
def on_error() -> Callable[[PTechECommerceErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[PTechECommerceErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_ssl_server_authentication Event

Fired after the server presents its certificate to the client.

Syntax

class PTechECommerceSSLServerAuthenticationEventParams(object):
  @property
  def cert_encoded() -> bytes: ...

  @property
  def cert_subject() -> str: ...

  @property
  def cert_issuer() -> str: ...

def on_ssl_server_authentication(event_hook: Callable[[PTechECommerceSSLServerAuthenticationEventParams], None]) -> None: ...

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

on_ssl_status Event

Fired when secure connection progress messages are available.

Syntax

class PTechECommerceSSLStatusEventParams(object):
  @property
