<h3>External services</h3>
<p>This plugin relies on the following third-party services. Data is only sent to a service when you enable and configure the related feature.</p>
<h4>Mollie payment gateway (api.mollie.com)</h4>
<p>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 <code>fair_payment_initiate_payment()</code>), 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.</p>
<ul>
<li>Terms of service: https://www.mollie.com/legal/user-agreement</li>
<li>Privacy policy: https://www.mollie.com/legal/privacy</li>
</ul>
<h4>Fair Event Plugins OAuth proxy (fair-event-plugins.com)</h4>
<p>Used only if you connect Mollie through the built-in OAuth flow instead of pasting a personal API key. The plugin redirects you to <code>https://fair-event-plugins.com/oauth/authorize</code> to authorize access to your Mollie account, and later calls <code>https://fair-event-plugins.com/oauth/refresh</code> 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.</p>
<ul>
<li>Terms of service: https://fair-event-plugins.com/terms/</li>
<li>Privacy policy: https://fair-event-plugins.com/privacy/</li>
</ul>
<h4>Telegram Bot API (api.telegram.org)</h4>
<p>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 <code>https://api.telegram.org/bot<token>/sendMessage</code> 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.</p>

<li>Terms of service (Bot API): https://telegram.org/tos/bot-developers</li>
<li>Privacy policy: https://telegram.org/privacy</li>
</ul>
<h4>Other WordPress sites you connect (hub / satellite data sharing)</h4>
<p>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.</p>

<h4>Why payments via Mollie?</h4>
<p>Why does Paytium only support Mollie as payment service provider?</p>
<ul>
<li>Mollie is one of the better payment provider with 32 cents per iDEAL | WERO transaction</li>
<li>Besides iDEAL | WERO , Mollie also supports many many other payment methods, and you just need one Mollie account</li>
<li>Your money can be automatically wired to your bank account daily</li>
<li>No hidden, setup or monthly costs, only pay for actual transactions for most Mollie users, (Depending on the amount and Mollie custom terms for increased risk or specific sectors. For specific, often “high-risk” sectors/businesses, a minimum Mollie monthly fee of €20 (or equivalent) may apply. This is not a standard Mollie subscription fee for everyone, but a measure to cover increased operational costs resulting from stricter anti-money laundering (WWFT) regulations and monitoring, thus deemed subject to custom terms for increased risk or for specific sectors).</li>
<li>For most standard Mollie users, no fixed monthly fees applies, but only is charged per actual transaction depending on the amount.</li>
<li>Fully certified by “De Nederlandsche Bank” (DNB), just like the big banks</li>
<li>Mollie is reliable & one of the very best in payments</li>
<li>Super fast and friendly helpdesk (via email and telephone)</li>
</ul>

<h4>Automatically process recurring payments</h4>
<p>Paytium also supports recurring payments, even for iDEAL | WERO payments. Setup a simple subscription, ask customers to pay once to confirm, and see how the next payments come into your bank account automatically.</p>
<p>Yes, recurring payments also work with iDEAL | WERO payments! When iDEAL | WERO is used for the first payment, the next (automatic) payments are processed with SEPA (automatische incasso).

<h4>What’s the big deal about iDEAL | WERO?</h4>
<p>Paytium supports almost all Mollie payment methods, including iDEAL| WERO but excluding Klarna.</p>
<p>The payment method iDEAL is a Dutch payment method supported by almost all Dutch banks.<br />
iDEAL is a semi-automated direct online transfer from the consumers bank account to your Mollie account/bank account for the Netherlands. Even though iDEAL is the most popular payment method in the Netherlands, other payment methods like PayPal are also popular. Our advice is to always accept at least iDEAL|WERO as payment method in your payment forms, and also enable all other payment methods that are available via Mollie. Consumers like to make payments in their favorite payment method, so it’s best to just allow them to make the payments in anyway they like!<br />
This most popular payment method in the Netherlands iDEAL will become WERO.<br />
The payment method WERO will be new, one, uniform, interoperable digital, pan-European wallet and a payment system method launched by the European Payments Initiative (EPI). WERO will enable direct, account-to-account payments between European countries, replacing local payment systems. Yes, replacing iDEAL.<br />
This transition will happen in phases. The first step is the new combined iDEAL|WERO logo as introduction. Aside from the logo, nothing will change in terms of functionality. Checkout will remain the same. iDEAL|WERO payments are through the Mollie dashboard. Behind the scenes Mollie will be making the necessary system preparations to enable the actual transition. In the Netherlands, the migration from iDEAL to WERO will begin in late 2026 and be completed by the end of 2027. WERO payments will then be activated through the Mollie dashboard.<br />
Paytium will continue to support almost all Mollie payment methods, including WERO but excluding Klarna.</p>
