About PSP-XML
From the official readme · v1.0Description
This WordPress plugin simplifies the checkout process by providing an easy-to-integrate solution for merchants. With a sleek and customizable checkout page, the plugin also supports Google Pay and Apple Pay, allowing customers to securely complete the transactions.
The PSP-XML’s Real-time XML API allows customers to process real-time credit card transactions via a server-to-server connection. This API is suggested for:
• Merchants developing and integrating a highly customized system
• Merchants who do NOT require PSiGate to collect and store credit card information
The XML Messenger Interface receives transaction requests sent by the Merchant. The transaction requests are then forwarded to PSiGate’s payment engine for real-time processing. An Order element encloses each XML transaction request, meaning that the request must begin with and end with. Each transaction request consists of transaction elements that define the request. The minimum number of transaction elements needed to successfully transmit an order depends on the type of transaction request.
Using Realtime-XML APIs
Merchants who have customized shopping carts and custom checkout pages or might already be using the Realtime-XML APIs for their integration with PSiGate can use this approach to accept payments via Apple Pay.
For convenience to our merchants and to reduce your dependencies, PSiGate will be taking up the authentication of your website with Apple and maintain your merchant account.
Key Features:
• Customizable Checkout Page: Allows merchants to personalize certain fields such as shipping or tax details.
• Transaction Processing: Securely processes payments using Google Pay and Apple Pay, with transactions routed through your custom server endpoint.
• Receipt Printing: Automatically generates and prints detailed receipts for customers after a successful transaction, streamlining post-purchase communication.
• Merchant Settings Page: Provides an intuitive settings page where merchants can configure payment options, modify checkout fields, and manage various customization settings to suit their needs.
