Web Service

The Web Service (WS) Client Application (CA) connects directly to the PaymentExpress Host WS via HTTPS Posts. Client applications talk to the Web Service using SOAP (Simple Object Access Protocol). SOAP provides a way to communicate between applications running on different operating systems, with different technologies and programming languages.

When consuming the web service at the "sec" subdomain (https://sec.paymentexpress.com/WS/PXWS.asmx) please ensure that your web service stack supports lax versioning: that is, it does not throw exceptions for new unknown data members in received data.

We no longer intend to update the web service exposed on the "www" subdomain (https://www.paymentexpress.com/WS/PXWS.asmx) with additional features or response elements as there are clients that were developed with the assumption that the schema will not change and they may fail to process messages that they were never designed for. Also, existing clients may perform actual schema validation against the old schema before even attempting to process the messages.

For this reason any future updates will be carried out on the new web service at the address below under the understanding that lax versioning is implemented on all clients consuming it. We will therefore not be required to establish a new end point in order to add extra data members. By the same token we will not require merchants to connect to a new endpoint in order to take advantage of any new features.

Installation Instructions

There is no Web Service installation to do on the client side as this is held at the Payment Express Host.

Additional Output Elements

Element Description
acquirerReco 2 character response code from the Acquiring bank
acquirerResponseText Response Text associated with ReCo from the Acquiring bank
 

Exception Handling

Refer to the GetStatus operation. The Payment Express architecture does not provide for customer applications to "reverse" or "back out" transactions once started. Exception conditions arise when the link between the customer application and the Payment Express Host is interrupted. A response to a transaction request is not received or the StatusRequired parameter in the response is true. In this circumstance, the result of the transaction is unknown.

The transaction must not be assumed to have failed. In this case, the application must enter a "recovery" mode until the result of the transaction can be ascertained. The mechanism to perform this error recovery is easily accomplished using the procedure outlined in the GetStatus method documentation.

GetStatus

GetStatus is used when the SubmitTransaction operation fails and the response was not received within a timeout period or the link to Payment Express Server or beyond failed while awaiting a response. In this circumstance, the result of the transaction is indeterminate. The GetStatus operation should be used to retrieve the actual result. GetStatus uses the original TxnRef values which uniquely identify the transaction to lookup the transaction at the Payment Express Host and return the results.

Input Elements

Element Required Description
postPassword Yes Combined with Username, selects Account
postUsername Yes Combined with Password, selects Account
txnRef Yes Value assigned to the txnRef property of the transaction to look up.
 

Output Elements

Element Description
authCode Authorisation Code
authorized 1 if transaction successful - 0 if declined or unsuccessful
billingId Billing Id specified for a token billing transaction
cardHolderHelpText Any tips or hints for the CardHolder. Usually just the Response Text, associated with the ReCo
cardHolderName Card Holder Name as on Card.
cardHolderResponseDescription A description of the transaction error to help the CardHolder, associated with the ReCo
cardHolderResponseText Response Text of the transaction to help the CardHolder, associated with the ReCo.
cardName Card used (Visa,MasterCard,Bankcard etc)
cvc2ResultCode Contains information regarding verification of cvc2.
dateSettlement Date transaction will be settled to Bank Account in YYYYMMDD format. This is supported for most, but not all banks and card acquirers. If the DateSettlement is not available from the banking network, the DateSettlement will contain the current calendar date.
dpsBillingId Contains the BillingId generated by Payment Express when adding a card for recurring billing.
dpsTxnRef Unique transaction identifier returned for every transaction. Required input for Refund transactions or Complete transactions.
reCo 2 character response code.
responseText Response Text associated with ReCo
retry If true; retry transaction, if false do not retry.
statusRequired If true then the result of the transaction could not be determined and you will have to call GetStatus again.
txnRef Set by client to uniquely identify transaction.
 

Example:

  1. Client Application loads the Web Service Input Elements
  2. Client Application uses the SubmitTransaction operation call and connects to the Web Service
  3. Web Service sends transaction
  4. Link between Web Service client application is interrupted
  5. Client application returns indeterminate result after timeout period
  6. Client Application calls the GetStatus operation
  7. Client Application receives the result of the transaction
 

Once the client application has confirmed the result of the transaction with the Payment Express Server with the GetStatus call, normal processing of subsequent transactions using SubmitTransaction method can resume.

Ensure that this txnRef value is loaded in txnRef property before calling GetStatus. Payment Express Host maintains transaction results for at least 48 hours therefore calls to GetStatus can rely on results being available for at least this period following transmission of the original transaction.

If a GetStatus method is made for a transaction that was successfully processed by Payment Express Host and was accepted by the bank, then the GetStatus method will result in the Web Service properties being set exactly as they would have been for the original transaction result, regardless of whether the original transaction result was actually received by the client application.

 

GetStatus2

This is used in the same way as GetStatus call, however it also includes the Acquirer response in the result.

Additional Output Elements

Element Description
acquirerReco 2 character response code from the Acquiring bank
acquirerResponseText Response Text associated with ReCo from the Acquiring bank


UpdateCard

UpdateCard call is used to update the expiry date of a BillingId, DpsBillingId or CardNumber2 associated with a credit card. This is useful when a customer's credit card has expired and they receive a new one from their bank with the same credit card number.

 

Input Elements

Element Required Description
postPassword Yes Indicates the Payment Express account under which the token is stored
postUsername Yes Authenticates the client application
cardDetails Yes An escaped XML document containing dateExpiry and BillingId, DpsBillingId or CardNumber2.


Output Elements

Element Description
UpdateCardResult An escaped XML document indicating the outcome of the operation.
 

The input SOAP message contains an element named cardDetails. The cardDetails string value should be an XML document which has be escaped before submission. dateExpiry and either billingId, dpsBillingId or cardNumber2 must be supplied.

Request example:

<cardDetails>
  <dpsBillingId>0000060000991568</dpsBillingId>
  <dateExpiry>1111</dateExpiry>
</cardDetails>

The output SOAP message contains a single element named updateCardResult. The updateCardResult string value contains escaped XML which must be unescaped in order to parse the values. The updateSucceeded value indicates the success of the update and the reco and responseText values provide further details.

Output example:

<updateCardResult>
  <updateSucceeded>1</updateSucceeded>
  <reco>OK</reco>
  <responseText>OK</responseText>
</updateCardResult>

Auth-Complete

Overview

Payment Express supports Authorisation and Complete transaction types. An Auth transaction verifies that funds are available for the requested card and amount, and reserves the specified amount. A Complete transaction is sent at a later date to cause funds transfer for the previously authorised amount, or a smaller amount if the total original value is no longer required. This transaction set is useful when the merchant needs to ensure that funds up to a certain limit are available but the actual total amount is not yet known or goods or services have not yet been delivered.

Operation

1) Authorization 

Use the SubmitTransaction operation with TxnType set to "Auth" for for the amount to be authorised. The Auth response contains a DpsTxnRef. The funds are not transferred from the cardholder account. 

2) Complete

After a successful Auth transaction, but within 7 days maximum, a Complete transaction must be sent containing theDpsTxnRef returned by the Auth transaction.

Token Billing

Overview

Token Billing allows for regular billing of a cardholder card, under the control of the merchant, without requiring the merchant to either store sensitive card data securely or to obtain credit card details every time a new payment is requested. This functionality is implemented by providing the ability for a merchant to request Payment Express to capture and store credit card number and expiry date and to link these stored details to a merchant supplied "BillingId". The BillingId is a 32 character field that contains a reference that is unique to the merchant's customer that will be associated with the credit card information stored securely at Payment Express. This is undertaken during the Setup Phase. For subsequent charges to the card (Rebill Phase), the merchant does not need to supply the card number or expiry date, only the BillingId originally associated during the Setup Phase

1) Setup Phase

A setup phase involves loading a card into Payment Express. Optionally the setup phase can include an online $1.00 authorisation (Validate) transaction which will determine that the card is valid and not on hot or stolen card lists and that it has the correct expiry date.

Customers will typically integrate directly into their call centre or web application for the setup phase.

To add a card for future rebilling, call the SubmitTransaction web service method/operation with the following properties -

TxnType property set to "Purchase" or "Auth"
EnableAddBillCard property set to "1" (true)
CardHolderName (optional, strongly recommended)
MerchantReference
CardNumber
DateExpiry
Cvc2
Cvc2Presence
BillingId (Optional. If none is supplied then a DpsBillingId determined by Payment Express will be returned for use)

2) Rebill Phase

The merchant application or Batch processor requests a new transaction and supplies the appropriate BillingId, orDpsBillingId a MerchantReference which appears on reports and the amount to be charged. EnableAddBillCard value will be set to 0 (False) for the rebill phase.
Payment Express retrieves the credit card number and expiry date stored in the Setup Phase and a purchase transaction is formatted and processed to the card acquirer.

CardNumber2

Note: CardNumber2 functionality is only available via SOAP Requests made to the subdomain "sec".

CardNumber2 is a token generated by Payment Express and associated with the card details supplied. It has 16 numeric characters and conforms to a Luhn "mod 10" algorithm. This makes it ideal for storage within the database in place of a card number where the value is validated against checks which might normally be made against credit card numbers. A CardNumber2 value is always unique for a given card number and includes a card type indicator. Should a card number be presented for tokenization multiple times the same CardNumber2 value will be returned.

CardNumber2 tokens are generated for all transactions once enabled by Payment Express (please contact your Payment Express account manager to discuss).The token will be returnd in the "cardNumber2" property of the transaction response "TransactionResult2".

Charging a CardNumber2 token involves a request from the merchant application or Batch processor including an appropriate cardNumber2, a TxnType (Purchase) and the amount to be charged (an optional MerchantReference can be added for reporting purposes). EnableAddBillCard value will need to be set to "False" (or 0) for the rebill phase. Payment Express® retrieves the credit card number and expiry date stored in the Setup Phase and a purchase transaction is formatted and processed to the card acquirer.

CardNumber2 transactions use the card expiry date stored with the token regardless of wheter one is passed through in the transaction data. On a successful transaction with the real card number accociated with a CardNumber2 token the expiry date stored with this token will be updated to that which was used to process the transaction. If your client application displays details of stored tokens to cardholders eg: masked number and expiry date, then it is advisible upon a successful transaction for the merchant application to update the expiry date that is stored with the generated token.

 

Refunds

The Web Service is capable of handling refunds (credit) transactions, however you will need to match the original Purchase or Complete transaction for this to happen. The matching is done with the DpsTxnRef given from the response of a purchase or complete transaction. You are able to do multiple refund transactions to the maximum amount of the original matched transaction.
The TxnType will be Refund.

The Payment Manager is provided to merchants with all integrated solutions by DPS, so there is a ready built interface to handle refund transactions already. However, if you wish to integrate refunds into your own interfaces the following input properties need to be provided for a refund transaction:

TxnType = "Refund"
DpsTxnRef
MerchantReference (Optional)
Amount

Extended Airline Booking Data

The Web Service is capable of taking extended booking information, which is used to display on cardholders statements.

If you would like to add booking information to your transaction details you will need to set the EnablePaxInfo input property to true (1) and you will be able to use the following properties -
PaxCarrier,PaxCarrier2,PaxCarrier3,PaxCarrier4,PaxDateDepart,
PaxDate,PaxDate3,PaxDate3,PaxDat4,paxTime1,paxTime2,paxTime3,paxTime4,
PaxLeg1PaxLeg2PaxLeg3PaxLeg4paxStopOverCode1paxStopOverCode2,
paxStopOverCode3paxStopOverCode4paxClass1paxClass2paxClass3paxClass4
paxFareBasis1paxFareBasis2,paxFareBasis3paxFareBasis4,
paxFlightNumber1paxFlightNumber2paxFlightNumber3paxFlightNumber4,
PaxOrigin,PaxNamePaxTicketNumber and PaxTravelAgentInfo.

Sample data:

PaxDateDepart = "14122008"
PaxName = "Brian Smith"
PaxOrigin = "AKL" 
PaxLeg1 = "SYD"
PaxLeg2 = "LAX"
PaxLeg3 = "LHR"
PaxLeg4 = "AKL"
PaxTicketNumber = "0030458343"
PaxCarrier = "QB"
PaxTravelAgentInfo = "BA1234567890"

Properties Description

The following section provides a detailed description of each Web Service element and indicates if it used as an input or output. If a property is marked as input, it is not updated or output when a call to SubmitTransaction or GetStatus returns. This is important when a call is made to GetStatus for example, the original contents of Amount as input to the SubmitTransaction call are not output by GetStatus.

A string value is used rather than the conventional Currency Datatype to allow for easy integration with Web applications. Note that the original  value used as input to  SubmitTransaction  is not returned by any subsequent DoGetStatus and must be stored by the application if required. Maximum value allowable is $99,999.99. Note that acquirer or card limits may be lower than this amount. When submitting transactions for currencies with no decimal division of units such as JPY the AmountInput must be in an appropriate format e.g. "10".

ReCo (output) Datatype: String Max 2 characters
Response Code generated by Payment Express Server (for locally declined transactions) or by the Card Acquirer (for host originated responses). The ReCo should not be checked by the client application, as these  values differ based on the acquirer. Use the Succes property to determine the result of a transaction. Refer to the Response Codes section for a list of valid response code errors generated by Payment Express.

ResponseText (output) Datatype: String Max 32 characters
Response Text associated with the response code of the transaction

Retry (output) Datatype: Boolean True/False
If true, then the transaction should be sent again - the transaction was declined due to a temporary error. If false, then the transaction should not be sent again, regardless of whether it was accepted or declined. The transaction result returned was not directly influenced by the card details supplied or the standing of the cardholder's account with the card issuer. Rather, the transaction result can be attributed to a transient state. Payment Express recommend that, if possible, the merchant resubmit the transaction within reasonable frequencies given that the duration of the state affecting transactions is unknown. If transactions are being repeatedly rejected in excess of that expected to be handled by the application these should be raised for manual intervention and the Payment Express support team contacted by the merchant.

StatusRequired (output): 1 (true) or 0 (false)
If true then the status of the transaction could not be determined, either because the server could not be reached, because of an error, or because the transaction is still in progress. Your application should call GetStatus until StatusRequired is false (0).

Optional free text fields. Usually assigned at origin website.

TxnRef (input / output) Datatype: String Max 16 characters
An identifier provided by your application to uniquely identify the transaction. This is the TxnRef supplied by the client to initiate the transaction, or, if not supplied, a TxnRef value internally generated by Payment Express on return. This is required as an input for GetStatus operations.
