  • PHP v7.2
  • php-curl
  • WordPress v4.9.8
  • WooCommerce v3.4.5

Installation

$ composer require itinerisltd/wc-worldpay

Setup

Payment response(redirection) and Enhancing security with MD5 are mandatory.

On WorldPay's integration setup page:

  1. Enable Enable the Shopper Response
  2. Enter <wpdisplay item=MC_callback> as Payment Response URL
  3. Enable Payment Response enabled?
  4. Enter a 25-char random passphrase as Payment Response password
  5. Enter a 30-char random passphrase as MD5 secret for transactions
  6. Enter instId:amount:currency:cartId as SignatureFields

Then, fill in the same information on WP admin dashboard - WooCommerce > Settings > Payments > WordPay.

Note that WorldPay truncate long Payment Response password without notices!

Security Concerns about WorldPay HTML API

  • Leaking MD5 secret for transactions
    • Allow evil hackers to set up fake checkout pages, pretending to be the merchant
    • WorldPay would accept these checkouts and charges the credit cards
  • Leaking Payment Response password
    • Allow evil hackers to pretending to be WorldPay
    • WordPress would accept evil hackers' payment callbacks and changes order payment statuses

Not Issue

If Payment Response password(also known ascallbackPW) is incorrect, InvalidResponseException is throw to stop the world. Credit card holders see white screen of death in such case.
