ifthenpay | Payments for Formidable Forms

ifthenpay Payments for Formidable Forms adds ifthenpay as a payment option on Formidable’s own “Collect a Payment” form action.

In plain terms you get:
* One Gateway Key on your ifthenpay Backoffice, usable across every form on the site
* A live, editable table of every payment method provisioned on that Gateway Key, with per-method enable/disable and a default method
* Automatic, secure hosted-page checkout with no PCI scope on your server
* Real-time status sync back into Formidable’s native Entries and Payments admin screens

All settings are managed within Formidable’s own Global Settings screen and your ifthenpay Backoffice. The plugin is designed so site owners can handle payments without requiring advanced technical knowledge.

Requirements

• An active ifthenpay merchant account with a Backoffice Key.
• A Gateway Key registered to that Backoffice Key, with the payment methods you want to accept provisioned on it.
• Formidable Forms (free) must be installed and active, with its bundled free payments module (this plugin does not currently support sites using the separate paid Formidable “Payments” add-on).
• WordPress 6.3+ and PHP 7.4+, with HTTPS (SSL) enabled on your site.

External Services

This plugin connects to the ifthenpay API (https://api.ifthenpay.com) to:

• Validate your Backoffice Key and list the Gateway Keys registered to it.
• Fetch the payment methods available and provisioned on your Gateway Key.
• Create a Pay by Link payment session when a form with an ifthenpay payment action is submitted.
• Register the webhook URL ifthenpay uses to notify your site when a payment completes.
• Look up a payment’s live status (/gateway/transaction/status/get) as a supplementary check while the payer waits for the async webhook.

Data sent includes: your Backoffice Key and Gateway Key (setup and settings screen); a payment reference id, amount, description, enabled accounts string, success/error/cancel return URLs, language, and optional link-expiry date and default method (on submission); your site’s callback URL (when saving settings); and the transaction id ifthenpay returned for that payment (for the live status check).

No card, MB WAY, or bank data is ever collected or stored on your server — the payer completes payment entirely on ifthenpay’s own hosted page. See ifthenpay’s terms of service (https://ifthenpay.com/termos-e-condicoes/) and privacy policy (https://ifthenpay.com/politica-de-privacidade/).
