Solidgate Card Payments and Other for WooCommerce

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 automatically identifies which gateway a webhook belongs to by trying each configured key pair in turn.

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+
