%feature_title Features


In this feature you can find different subfeatures which are design to allow integrations to manage payment links. They are useful in a scenario where merchants have applications with payments receiving flows (invoices, service bills, etc.) instead of a platform where their clients go to buy goods and does not want to insert manual steps to contact each customer and perform the payment.

HOSTED PAYMENT PAGE INTEGRATION

This features uses the HPP mechanisms and features available and configured for your terminals during a payment - Hosted Page Payment (HPP) Features -

Once a link is created and sent to a customer it's possible to click on the link to be redirected to a Hosted Payment Page. There, the customer is able to perform the payment.

Depending on the HPP Feature's Settings, you might be able to perform a background validation on each transaction - HPP Background Validation - and at the end of the transaction you are going to receive a response at the Receipt Page URL, also configured at your terminal, containing all the details on the transaction's result.

For more details on the response to be received using the Receipt Page URL, refer to the Response Body Fields section on Hosted Page Payment Features page. Also, don't forget that this URL (Receipt Page URL) works as a webhook where you need to implement a mechanism to treat the information received, if you want to use it somehow.

DEFAULT RECEIPT PAGE

In case a terminal being used with HPP does not have a Receipt Page URL, the gateway is not going to send back the details regarding the transaction's result, but it's going to present a default receipt page providing feedback to the customer with a simpler receipt version.

The following resources are the same for all the requests and responses you find on this page:

TYPE URL
Request URL https://testpayments.worldnettps.com/merchant/xmlpayment
XML XSD descriptor https://testpayments.worldnettps.com/merchant/gateway.xsd

Use the Request URL and the Request Body Fields to perform a request for this feature, then prepare your integration to receive the response, as defined by the Response Body Fields.

This feature allows you to create links.

CONSTRAINT DESCRIPTION
C001 The terminal (TERMINALID) should support Internet (HPP) to use this feature.
C002 The terminal (TERMINALID) should be completely configured and active to use this feature.
C003 The currency (CURRENCY) should be supported by the Terminal.
C004 The Expiration Date (EXPIRATION_DATE) cannot be placed in the past
C005 The Expiration Date (EXPIRATION_DATE) cannot be before Creation Date
C006 The Merchant Ref (MERCHANTREF) should be unique for the Terminal
C007 Only terminals which support Pre-Auth allow integrations to choose the AUTH_TYPE.
C008 Only terminals which support Level II Enhanced Data allow integrations to inform the LEVEL_2_DATA.
C009 If a terminal defines Level II as compulsory, the Tax Amount is mandatory and other level2 fields might be present or not.
C010 The gateway is always going to validate the consitency among the value fields of the request, meaning that SUBTOTAL, TAX (and TAX_AMOUNT from LEVEL_2_DATA, when informed) and AMOUNT will be validate among themselves.
C011 If a request is submitted without the TAX, the terminal allows the Level 2 Enhanced Data and the TAX_AMOUNT was informed, the gateway is going to calculate the TAX percentage to keep consistency.
C012 If a request is submitted with the TAX, the terminal allows the Level 2 Enhanced Data and the TAX_AMOUNT was informed, the gateway is going to validate them considering the transaction's SUBTOTAL and AMOUNT.
C013 If a request is submitted with at least one ITEM in ITEMS, the SUBTOTAL field becomes mandatory.
C014 If a request is submitted with at least one ITEM in ITEMS, the SUBTOTAL field is going to be validate against the sum of all the ITEM's ITEM-AMOUNT.
C015 All the values present on the request are going to be validated against the informed CURRENCY for format.
