Riskloom Fraud Screening for Signifyd

Signifyd has no official WooCommerce integration. It ships supported plugins for Magento 2, Salesforce Commerce Cloud, and BigCommerce, leaving WooCommerce stores to build their own. This plugin is that integration, written directly against Signifyd's REST API using WordPress's own HTTP client. When an eligible order is paid, the plugin builds a case from the order and submits it to Signifyd for screening. Signifyd returns its risk score and guarantee decision over a signed webhook, which the plugin verifies and stores on the order. Staff get a compact panel on the order screen showing the score and disposition, with buttons to refresh the case, dismiss it, or purchase Signifyd's financial guarantee. Features

• Creates a Signifyd case automatically when an eligible order is paid
• Verifies signed webhooks (HMAC-SHA256) and stores the resulting score and guarantee disposition on the order
• Order-screen panel for staff: view case, refresh, close case, purchase guarantee
• Filterable payment-gateway meta mapping, so the plugin is not tied to one gateway
• Compatible with High-Performance Order Storage (HPOS)
• No bundled SDK and no vendor dependencies; the API client is a few hundred lines on top of the WordPress HTTP API
• API key can live in wp-config.php instead of the database

Choosing which orders get screened Screening is limited to the payment gateways you select on the settings screen, so only credit-card orders are sent. You choose whether the case is created on payment completion or when the order reaches processing status. A filter (wc_signifyd_order_is_eligible) lets you refine that per order. What it deliberately does not do

• It never handles card numbers or CVV values. Only risk-signal fields your gateway has already stored are read: AVS and CVV match results, card BIN, last four digits, and expiry.
• It never writes request or response bodies to logs. Logging goes through the WooCommerce logger and records order IDs, case IDs, and status codes only.
• It never changes order status on its own. A DECLINED guarantee stores the disposition and fires the wc_signifyd_case_updated action so each store can apply its own policy, rather than cancelling orders behind your back.

Which Signifyd API this uses This plugin calls the Signifyd V2 Cases API. Signifyd's current documentation promotes the V3 Decisions API for new integrations, and V2 remains available to existing teams. Confirm with your Signifyd account team which API version your credentials are provisioned for before installing. Extending it Ten filters and actions are available, covering gateway meta mapping, AVS code translation, order eligibility, the full case payload, request timeout, and a post-update action for custom workflow. The full reference lives in docs/ARCHITECTURE.md in the source repository. Who maintains this Choice OMG maintains this plugin. We are a digital marketing and web agency in Edmonton, Alberta, and we wrote it because a client's WooCommerce store needed Signifyd screening that Signifyd does not ship for WooCommerce. It runs in production on that store against the Moneris gateway. Setup notes and gateway mapping guidance live at Choice OMG.

1. Upload the plugin to wp-content/plugins/riskloom-fraud-screening-for-signifyd/, or install it from the Plugins screen.
2. Activate it through the Plugins screen. WooCommerce must be active.
3. Go to WooCommerce > Settings > Signifyd and enter your Signifyd team API key.
4. On the same screen, choose which payment gateways are screened and which order event creates the case.
5. Copy the webhook URL shown on that screen into the Signifyd console under Settings > Webhooks, subscribed to at least Case Creation, Case Rescore, Case Review, and Guarantee Completion.

Keeping the API key out of the database Define it in wp-config.php instead of using the settings field: define( 'WC_SIGNIFYD_API_KEY', 'your-team-api-key' ); The constant overrides the stored option, and the settings field is shown disabled with a note explaining why.

1.2.3

• Pointed the Plugin URI at the plugin's page on choice.marketing instead of the GitHub repository.
• Added listing screenshots.

1.2.2

• Renamed the plugin to "Riskloom Fraud Screening for Signifyd" so the name leads with a distinctive term rather than a generic description.
• Removed the load_plugin_textdomain() call, which WordPress has not needed since 4.6 and this plugin's minimum of 6.0 can never reach.
• Added the plugin owner to the contributor list.

1.2.1

• Renamed the plugin in both admin notices, which still used the pre-1.2.0 name.
• Corrected the Plugin URI capitalisation to match the canonical repository path.
• Regenerated the translation template against the corrected strings.

1.2.0

• Fixed the AVS mapping comment never being saved, which left that line blank in the order panel on every order.
• Fixed the duplicate-case guard being ineffective on sites with a persistent object cache, where it could allow two Signifyd cases to be created for one order.
• Stopped writing Signifyd error-response bodies into the WooCommerce log; only the HTTP status code is recorded now.
• Renamed the plugin for WordPress.org directory compliance. Internal hooks, options, and the webhook URL are unchanged.
• Added a translation template, documented every function and class, and added architecture and contributor documentation.
• Refreshed compatibility: tested against WordPress 7.0 and WooCommerce 11.0.
