Hosted Page Payment Features


This feature has two subfeatuers: the Payment and Pre-Authorization.

Use the Request URL and the Request Body Fields to perform a request for those subfeatures, then put in place your Receipt URL so the gateway can use the Response Body Fields to send the transaction's receipt.

Payment and Pre-Authorization

These features enables you to perform a Payment transaction or a Pre-authorization transaction, using a hosted page at the Payment Gateway.

This page is built to allow merchants to easily integrate with the Worldnet system for processing one-off payments.

Using this solution, the Card Holders are redirected to the Gateway's payment page once they have made the decision to buy something at the Merchant's solution. All payment details are collected by Gateway's payment page to be sent to the Acquirer's Server once the submit button is pressed. The payment is then processed by Gateway and the Card Holder is redirected to the Merchant's Receipt page.

The above is accomplished by means of a simple HTML form post with a number of defined form fields, as you will see at the following subsections.

Both requests (Payment and Pre-auth) have the same body, but different Request URLs to be used.

TYPE REQUEST URL
Payment (Authorization) https://testpayments.worldnettps.com/merchant/paymentpage
Pre-Authorization https://testpayments.worldnettps.com/merchant/preauthpage

Their values are going to be stored and used by the Payment Gateway for the requests sent to the Receipt URL and the Validation URL. To understand more visit the section regarding Special Fields and Parameters.
OTHERFIELD N Any other fields sent in the request will be treated as a custom field. They are not going to be stored, but they are going to be used by the Payment Gateway for the request sent to the Receipt URL. Note that this is subject to the max length of a HTTP GET request which we would conservatively recommend considering to be 2000 characters.

Notes and Details About the Request

ND001 - Hash Formation

The gerenal rule to build HASH field is given at the Special Fields and Parameters page. For this specific feature, you should use the following formats:

When using a Single Currency Terminal, the string to generate the HASH field is going to formed using:

TERMINALID:ORDERID:AMOUNT:DATETIME:RECEIPTPAGEURL:VALIDATIONURL:SECRET

When using a Multi Currency Terminal, the string to generate the HASH field is going to formed using:

TERMINALID:ORDERID:CURRENCY:AMOUNT:DATETIME:RECEIPTPAGEURL:VALIDATIONURL:SECRET


ND002 - Hosted Page in an iFrame

It is also possible to process transactions using an iFrame rather than a full redirect. All the same fields are required as the standard full redirect integration. However, the implementation for the iFrame is slightly different. There are two methods of implementing it on an iFrame:

  • 1. Build and submit the form as with standard integration, but within the iFrame.
  • 2. Build the POST query string within the main page and then create an iFrame with the string as it's SRC value.

In either case, the following extra parameter should also be included at the request body:

FIELD REQUIRED VALUE DESCRIPTION
INIFRAME YES Y Ensures that all redirects performed by our system do not break out of the iFrame.


ND003 - Secure Card Registration by Payment Request

It is also possible to take advantage of a Payment Request to register a Secure Card. In this case, the following extra parameter should also be included at the request body:

FIELD REQUIRED DESCRIPTION
SECURECARDMERCHANTREF Y Unique Reference assigned by the merchant site/software to identify the stored card details. Its length is limited to 48 characters.


ND004 - Level 2 Data Validation

These fields are associate with of the Transaction`s Level 2 Enhanced Data. To be used, it's necessary that your terminal has the enhanced data enabled and set to LEVEL 2 or LEVEL 3. All of its fields, except for SHIPPING_ADDRESS2, are necessary if you want to have a better chance to qualify for Level 2 with your acquirer, but no field is actually mandatory.

This feature is only available for specific acquirers (contact our support team for more details).


ND005 - Multi Language Support

Depending on your customer's browser definitions and if there's a language template defined for his/ her language priority, the Payment Gateway is going to send the payment receipt translated. If the language is not supported by the gateway, the receipt is going to be sent using the gateway's language.

Notes and Details on the Response

ND001 - Hash Formation

The gerenal rule to build HASH field is given at the Special Fields and Parameters page, under the Special Fields and Parameters section.For this specific feature, you should use the following formats:

  • Common case:

TERMINALID:ORDERID:AMOUNT:DATETIME:RESPONSECODE:RESPONSETEXT:SECRET

  • When the original request also requested the registering of a Secure Card:

TERMINALID:ORDERID:AMOUNT:DATETIME:RESPONSECODE:RESPONSETEXT:SECRET:MERCHANTREF:CARDREFERENCE:CARDTYPE:CARDNUMBER:CARDEXPIRY

When using a Multi Currency Terminal, the string to generate the HASH field is going to formed using:

ND002 - Sentinel Defence Enabling

Sentinel Defence must be enabled for your Gateway and on the Terminal used for processing the transaction request.


ND003 - Sentinel Defence REVIEW status

If a transaction is returned with “FRAUDREVIEWSTATUS” as “REVIEW”, this transaction can be changed manually, using the new report feature on %Selfcare System, or using the transaction update XML gateway service, to “APPROVE” or “REJECT” the transaction. Transactions with this status are not going to be settled until the transaction status is changed. See the XML Gateway method for more details, more specifically, its Transaction Update feature, to change the transaction returned as “REVIEW” to “REJECT” or “APPROVE”.


ND004 - Secure Card Registration by Payment Request

When the SECURECARDMERCHANTREF field is sent on request, the Payment Gateway understands that you desire to create a Secure Card from the card data used for the transaction. In this case, the following extra parameter are going to be added to the response body:

FIELD DESCRIPTION
ISSTORED Values can be: true or false.
SCERROR Description of storage error if ISSTORED is “false” .
MERCHANTREF Original SECURECARDMERCHANTREF provided by the Merchant on request.

CONSTRAINT DESCRIPTION
C001 The hosted Pre-Auth page allows for pre-authorization where the merchant account allows such requests.
C002 Pre-auth transactions don't have the concept of Auto Ready, so to go into the READY state, they need to be completed using Self Care System or via an XML Completion request before they will be settled.
C003 The final amount of a pre-auth transaction can be adjusted on completion.
