Description

Solidgate Card Payments and Other for WooCommerce integrates the Solidgate payment platform into your WooCommerce store with support for card payments and a range of alternative payment methods (APMs).

Card Payments

Solidgate Card (sg_card) — An inline card form powered by the Solidgate Payment Form SDK. Card details are entered directly on your checkout page inside a secure Solidgate-hosted iframe. Supports 3-D Secure, refunds, and async webhook confirmation.

Alternative Payment Methods

MB WAY (sg_mbway) — Push-notification payments for Portugal. The customer enters their MB WAY phone number and approves the payment on their MB WAY app. Available for EUR orders to Portuguese billing addresses.
Bizum (sg_bizum) — Mobile payments for Spain. The customer is redirected to Bizum’s hosted page and returns to your site after approval. Available for EUR orders to Spanish billing addresses.
BLIK (sg_blik) — One-click payments for Poland. The customer enters a 6-digit BLIK code from their banking app. Available for PLN orders to Polish billing addresses.
iDEAL (sg_ideal) — Bank transfer payments for the Netherlands. Available for EUR orders to Dutch billing addresses.
Pay by Bank (sg_openbanking) — Open Banking payments available across supported regions.

All payment methods share a single admin plugin, one REST namespace (solidgate/v1), and a unified webhook setup.

Webhook URL

All payment methods share a single webhook endpoint. Configure this URL in Solidgate Hub (Settings Webhooks):

https://yoursite.com/wp-json/solidgate/v1/webhook

The plugin identifies which gateway a webhook belongs to from the Solidgate order ID prefix, then verifies the request signature against that gateway’s configured webhook keys.

Requirements

WooCommerce 6.0 or higher
A Solidgate merchant account
API keys from Solidgate Hub (separate keys for Card vs APM gateways)
PHP 7.4+

External Services

This plugin communicates with the following Solidgate domains to process payments, refunds, and order status updates. It does not send data to any other third party.

gate.solidgate.com — Alternative payment method (APM) order status checks (Bizum, BLIK, iDEAL, MB WAY, Open Banking).

pay.solidgate.com — Card payment status checks and refund requests.

cdn.solidgate.com — Loads the Solidgate Payment Form SDK (solid-form.js), the JavaScript library that renders the inline card form on your checkout page.

Data sent:

Payment details (amount, currency, order ID) when a customer initiates a payment.
Refund requests initiated by the merchant from the WooCommerce order screen.
Webhook signature validation on incoming payment status events.

When data is sent: Only when a customer places an order using a Solidgate payment method, when the merchant requests a refund, or when the checkout page loads the Card payment form.

Solidgate Terms of Service: https://solidgate.com/terms-of-service/
Solidgate Privacy Policy: https://solidgate.com/privacy-policy/

No payment data is stored on your server. All sensitive card data is handled by Solidgate’s PCI-DSS compliant infrastructure.

Changelog

1.0.3

Fix: the “declined”/”fail” webhook handling for Bizum, BLIK, iDEAL, MB WAY, and Open Banking could revert an order that had already been paid back to “failed” if a stale or duplicate webhook arrived after a later successful one. Card already guarded against this; the guard is now applied to all six gateways via a shared base class.
Compliance: == External Services == now discloses all three contacted Solidgate domains (gate.solidgate.com, pay.solidgate.com, cdn.solidgate.com) instead of only one.
Internal: removed a duplicated direct-SQL patch against WooCommerce’s internal wc_orders table that was present in all six webhook handlers; the existing retry-on-4xx path already covers the same “order not found yet” case without writing to WooCommerce-owned tables.
Internal: unified webhook dispatcher now returns consistent HTTP status codes (403 invalid signature, 404 order not resolvable, 200 handled) for every gateway, not only Card.

1.0.2

Renamed plugin display name to “Solidgate Card Payments and Other for WooCommerce”.

1.0.1

Security: poll-status REST endpoints now require order_key for order enumeration protection.
Compliance: added == External Services == section documenting Solidgate API usage.
Compliance: text domain and class prefix updated for WordPress.org submission requirements.

1.0.0

Initial release — unified plugin combining Card, MB WAY, Bizum, BLIK, iDEAL, and Pay by Bank gateways.
REST namespace: solidgate/v1.
