Fair Payments Connector for WordPress Plugin Directory

Fair Payments Connector is the money layer for your WordPress site: it takes payments through Mollie and keeps the records that follow. Drop the Simple Payment block on any page to charge a one-off amount, or pair it with Fair Events to sell tickets — either way, every payment lands as a clean, itemized transaction you can trace from checkout to your bank statement.

Fair pricing, no subscription: Install for free — every feature is included, with no premium tier. Instead of charging upfront, a 1% integration fee on ticket sales is collected automatically in the payment flow, capped at €12/month for the whole plugin suite: sell nothing in a month, pay €0; sell for €200, pay €2. If your sales never reach €1,200 in a month, you pay less than the €12 sticker price. See fair-event-plugins.com for details.

Key Features:

Mollie Checkout in Minutes: Connect your Mollie account with a guided flow and switch between test and live modes

Your Payment Methods: Whatever you enable in your Mollie account — iDEAL, credit cards, Bancontact, PayPal, bank transfer, and more

Simple Payment Block: Take a payment from any page; set amount, currency, and description right in the editor

Ticket Checkout for Fair Events: Powers the paid signup flow of Fair Events automatically when both plugins are active

Reliable Status Tracking: Webhooks plus proactive status sync, so a payment stuck in “pending” recovers on its own

Bookkeeping Included: Budgets and a financial-entries ledger; import bank statements and reconcile them against your transactions

Instant Notifications: Optional Telegram message the moment a payment succeeds or fails

Multi-Site Ready: Satellite sites can pull their own transaction data from a central hub over a token-secured API

Fair Pricing Model: No premium tiers or hidden features – everything is included

Perfect For:

Event organizers selling tickets with Fair Events

Community groups and nonprofits collecting fees or donations

Associations that want payments and simple bookkeeping in one place

Anyone who needs a payment button on a WordPress page without setting up a webshop

External services This plugin relies on the following third-party services. Data is only sent to a service when you enable and configure the related feature.

Mollie payment gateway (api.mollie.com) Used to process payments. When a customer initiates a payment through the plugin (for example by submitting the Simple Payment block, or when another plugin calls fair_payment_initiate_payment()), the plugin contacts the Mollie API to create the payment and later to retrieve its status (including via Mollie webhooks and periodic status sync). Data sent includes: payment amount and currency, description, redirect/webhook URLs of your site, customer billing email when provided, and your Mollie access token. Mollie is operated by Mollie B.V.

Terms of service: https://www.mollie.com/legal/user-agreement

Privacy policy: https://www.mollie.com/legal/privacy

Fair Event Plugins OAuth proxy (fair-event-plugins.com) Used when you connect Mollie through the built-in OAuth flow. The plugin redirects you to https://fair-event-plugins.com/oauth/authorize to authorize access to your Mollie account, and later calls https://fair-event-plugins.com/oauth/refresh to refresh the Mollie access token when it expires. Data sent includes: the OAuth refresh token stored in your site and, during initial authorization, the parameters Mollie returns to the proxy. The proxy is operated by the plugin author (Marcin Wosinek) and exists because Mollie OAuth requires a registered client secret that cannot ship in a public plugin.

Terms of service: https://fair-event-plugins.com/terms/

Telegram Bot API (api.telegram.org) Used only if you configure a Telegram bot token and chat ID in the plugin settings to receive payment notifications. When a payment event occurs (such as a payment being marked as paid or failed), the plugin sends an HTTP request to https://api.telegram.org/bot<token>/sendMessage containing the notification text (transaction id, amount, status, and a link back to the admin transaction page) and the configured chat id. The Telegram Bot API is operated by Telegram FZ-LLC / Telegram Messenger Inc.

Other WordPress sites you connect (hub / satellite data sharing) If you use the connected-sites / data-sharing feature, the plugin will send authenticated REST requests to the WordPress site URLs you explicitly enter in the “Connected sites” admin page so it can pull transaction data. No data is sent to those sites unless you configure them yourself. There are no third-party terms for this feature — the remote endpoint is another WordPress site running this same plugin, under your control.

Developer Notes Public PHP API for integration from other plugins:

fair_payment_create_transaction( $line_items, $args )

fair_payment_initiate_payment( $transaction_id, $args )

fair_payment_get_transaction( $transaction_id )

fair_payment_sync_transaction_status( $transaction_id )

Transactions move through a status lifecycle (draft → pending_payment → paid/failed) with action hooks such as fair_payment_paid fired on each change.

The plugin is open source and contributions are welcome on GitHub.
