Hi, I need to add a page for clients to pay invoices on my website pswevents.com using our existing virtual terminal at Barclaycard UK using the information from their solutions page -
https://support.epdq.co.uk/integration-solutions/integrations/hosted-payment-page#e_commerce_integration_guides_payment_page_look_and_feel
I will need to send a page link to my clients and they will fill in the Invoice number / amount along with the payment details required by the ePDQ terminal.
‘Pay by Link’ using Barclaycard’s payment gateways can be developed by the merchant’s web developer using the standard integration instructions.
The need would be for the web developer to integrate using standard web-code (e.g. PHP, ASP, .NET etc.) to create a URL that includes the domain of the payment page with relevant data appended to that URL as session information and embed that URL into an email sent to the customer.
For example, a standard integration of ePDQ would require the following parameters to be “hashed” (encrypted) before being sent to the Hosted Payment Page along with the customer:
PSPID = Example123
AMOUNT = 100
LANGUAGE = en US
CURRENCY = GBP
ORDERID = Invoice1234
These “name=value” pairs are hashed/encrypted against a secret word, known only to the web developer, and configured in the ePDQ Back Office (referred to as SHA-IN Passphrase), to create an additional “name=value” pair:
SHASIGN=b7e4438d3cf6dda49aa8ffc1c4fb61ef038ac75e
All of these “name=value” pairs are then sent to the ePDQ Hosted Payment Page along with the cardholder. An example of the type of URL you might see when redirecting the customer to the ePDQ Payment Page using the example data supplied above would be:
https://[PAYPAGE URL]?AMOUNT=100&CURRENCY=GBP&LANGUAGE=en_US&ORDERID=1&PSPID=Example123&SHASIGN=b7e4438d3cf6dda49aa8ffc1c4fb61ef038ac75e
(Please note, this URL is provided for example purposes only and is not the correct URL for the Hosted Payment Page. For all integration parameters and settings, including the correct payment page URL, please refer to the relevant integration documentation.)
The additional code required to create emails and embed links in them uses completely standard web-based coding protocols available as standard in all server-side coding languages.
For a deeper understanding of how this could be implemented, the recommendation would be to review the ePDQ integration guides at https://support.epdq.co.uk/en to gain a clear understanding of how ePDQ works, combined with investigation of the many online repositories that provide sample web code.
Please only assist if all of the Barclaycard hosted payment page solution code is fully understood as I can only help with login details to the Wordpress site and epdq terminal as required for testing. |
