Interpay Payments

Interpay Payments is a WooCommerce payment gateway that lets your store accept credit and wallet payments through Interpay’s secure hosted payment fields.

Features:

  • Accept creditcard and wallet payments through the Interpay hosted payment form (card data never touches your server).
  • Test (sandbox) and Live (production) modes with separate API keys.
  • HPOS (High-Performance Order Storage) compatible.
  • Refund processing directly from the WooCommerce order screen.
  • Stores transaction reference, approval code, exchange rate, and SAR-converted amount on the order for reconciliation.

External services

This plugin relies on the following third-party / external services. By using this plugin, you agree that these services may receive data from your site as described below.

1. Interpay Payment Gateway API (interpayapimanagement.azure-api.net)

This plugin connects to the Interpay payment gateway API (hosted at https://interpayapimanagement.azure-api.net) to create payment orders, process card transactions, and issue refunds. Without this connection the plugin cannot accept payments.

It sends the order amount, currency code, a unique order or session identifier, the customer name, and the customer email every time a customer initiates a payment with Interpay or a store administrator issues a refund. For logged-in customers it additionally sends the billing address line 1, address line 2, city, and country code so the gateway can perform address verification.

Endpoints contacted: https://interpayapimanagement.azure-api.net/api/v1/Order/Create and https://interpayapimanagement.azure-api.net/api/v1/Transaction/Refund.

This service is provided by Interpay: Terms and Conditions and Privacy Policy.

2. Interpay Hosted Payment Page JavaScript (softpos-ksa.com)

This plugin loads a JavaScript file from Interpay’s hosted payment page service (hosted at https://ecomspghostedpage.softpos-ksa.com in test mode and https://prodhpg.softpos-ksa.com in live mode). This file renders the secure card-input iframe on the checkout page so that the customer’s card details are captured by Interpay directly and never reach your server.

The script is requested by the customer’s browser every time the customer reaches the Interpay checkout step. Card details (number, expiry, CVV) entered into the iframe are submitted from the customer’s browser directly to Interpay; your server only receives a tokenized reference.

Endpoints contacted: https://ecomspghostedpage.softpos-ksa.com/js/interpay.js (sandbox) and https://prodhpg.softpos-ksa.com/js/interpay.js (production).

This service is provided by Interpay: Terms and Conditions and Privacy Policy.

3. ExchangeRate-API public endpoint (open.er-api.com)

When the WooCommerce store currency is not SAR, this plugin calls the public ExchangeRate-API endpoint at https://open.er-api.com/v6/latest/{CURRENCY_CODE} to obtain the conversion rate from the store currency to SAR. Interpay only settles payments in SAR, so non-SAR stores require this conversion.

It sends only the source currency code (for example “USD” or “EUR”) as part of the URL path. No order data, no customer data, and no store-identifying information is transmitted. The retrieved rate is cached for 12 hours per currency via the WordPress transients API, so a call is made at most once every 12 hours per source currency.

Endpoint contacted: https://open.er-api.com/v6/latest/{CURRENCY_CODE}.
