Payment Collection

• Hosted Tokenization iFrame — Card data is entered inside an accept.blue-hosted iFrame embedded in your form. Raw card numbers never pass through your server, reducing PCI DSS scope and liability.
• One-time charges — Charge a fixed or dynamic amount on form submission, perfect for event registrations, donations, or product sales.
• Authorize-only mode — Place a hold on the card without capturing funds. Capture or adjust manually from the admin panel when ready to settle, giving you flexibility in billing cycles.
• 3-D Secure 2 (3DS2) — Optional browser-based authentication per form action, adding liability shift for card-not-present transactions and reducing fraud risk.

Recurring Billing and Installments

• Recurring subscriptions — Supported intervals: daily, weekly, bi-weekly, monthly, quarterly, bi-annually, and annually. Schedules are created in accept.blue and linked to the Formidable entry for full visibility.
• Installment plans — Split a total charge into automatic payments over a chosen interval. Ideal for tuition, memberships, deposits, or service packages.

Recurring billing ensures predictable revenue streams, while installment plans make higher-ticket services more accessible to customers. Both options are fully automated, reducing administrative overhead.

Refunds, Voids, and Captures

• Refunds — Issue full or partial refunds directly from the Formidable Forms payment detail page without leaving WordPress.
• Voids — Cancel an unsettled authorization before capture, preventing unwanted charges.
• Capture and Adjust-Capture — Settle a prior authorization at the original or adjusted amount from the admin panel.

These features give administrators complete control over transaction lifecycles, ensuring accurate reconciliation and customer satisfaction.

Admin Transactions Panel

• Dedicated WordPress admin screen listing all accept.blue transactions linked to Formidable Forms entries.
• Filter by date range, transaction status, or form for quick reporting.
• Revenue summary statistics displayed at the top for instant insights.
• One-click sync to pull latest transaction status from accept.blue.
• CSV export for accounting, reconciliation, and reporting workflows.

The transactions panel acts as a financial dashboard inside WordPress, eliminating the need to switch between multiple systems.

Webhooks

A signed REST API webhook endpoint receives real-time payment lifecycle events from accept.blue — including charges, settlements, refunds, and subscription events — and updates WordPress transaction records automatically. Signature verification ensures only legitimate payloads are processed, maintaining data integrity.

Fraud Shield

• IP velocity — Block or flag submissions from IPs exceeding a charge threshold.
• Email velocity — Limit transactions tied to the same email address.
• BIN block-list — Reject cards matching specified Bank Identification Numbers.
• Country block-list — Decline cards issued in specified countries.
• Amount thresholds — Set min/max charge amounts to catch anomalies.

Fraud Shield provides proactive protection, reducing chargebacks and safeguarding your merchant account reputation.

Developer Tools

• Debug logging — A dedicated log file records API requests and responses, gated behind a settings toggle.
• Actions and filters — Hooks for customizing charge arguments, subscription parameters, transactions panel, and payment events.

Developers can extend the plugin to fit unique business requirements, ensuring flexibility for advanced workflows.
