About this plugin
1 API. The customer is redirected to the SimplePay payment page; card details never reach the shop and are never stored there.
Current main features:
- A WooCommerce payment method under the payment settings.
- Sandbox and live systems, test mode on activation.
- A separate merchant account per currency (HUF, EUR, USD) — the order’s currency selects the right one.
- Starting the payment ( start ) and redirecting to the SimplePay payment page.
- Receiving, authenticating and properly acknowledging the IPN; this is what marks the order as paid.
- Full and partial refunds from the WooCommerce refund flow ( refund ).
- Manual transaction status query from the order screen ( query ).
- Displaying the mandatory data transfer statement at checkout, with the configured company details.
- Clone detection: if a live database ends up on another host, every outbound call pauses until someone decides what this site is.
- Controlled WooCommerce logging, with the secret key and signature masked.
Important notes
The IPN URL must be set up separately on every merchant account, in the SimplePay merchant interface — there is a separate account per currency, so a separate setting per currency. The URL is shown on the plugin’s settings page.
The customer’s return from the payment page ( back ) is for information only: the data arrives through the browser. Only the IPN, or a manual status query, financially marks the order as paid.
Two-step payment, card storage, recurring payment and wallet payments (Apple Pay, Google Pay) are not supported in this version.
External services
This plugin connects to SimplePay, the online payment service operated by
, to take card payments. This connection is required for the
payment method to work: without it no payment can be started, confirmed or
refunded.
Data sent, and when:
- Starting a payment (when a customer places an order with SimplePay
selected): the order total and its currency, the order reference
(orderRef), the customer’s email address, the customer’s full name
(first and last name), the customer’s billing address (country, state,
city, postcode, address lines 1 and 2) and phone number, the checkout
language, the merchant account id and the shop’s return URL. The plugin
then redirects the customer to the service’s hosted payment page. Card
details are entered there and never reach this shop. The name, billing
address and phone number are personal data.
- Refunding a transaction (shop owner action): the order reference
and/or SimplePay’s transaction id (whichever is known), the currency
and the refund amount.
- Re-querying a transaction’s status (shop owner action): the order
reference and/or SimplePay’s transaction id (whichever is known). No
amount or personal data is sent for a query.
