<h3>External Services</h3>
<p>This plugin relies on the Payment4 API, a third-party external service, to process cryptocurrency payments. The plugin will not function without connecting to this service.</p>
<h4>What is the Payment4 API?</h4>
<p>Payment4 (https://payment4.com) is a cryptocurrency payment gateway service that processes crypto transactions, monitors blockchain confirmations, and manages payment verification.</p>
<h4>When does the plugin connect to Payment4 services?</h4>
<p>The plugin connects to Payment4 external services in the following situations:</p>
<ol>
<li><strong>During Checkout</strong> – When a customer selects Payment4 as their payment method and proceeds to pay</li>
<li><strong>Payment Verification</strong> – When verifying that a cryptocurrency payment has been received and confirmed on the blockchain</li>
<li><strong>Payment Callbacks</strong> – When Payment4 sends webhook notifications about payment status updates</li>
<li><strong>Language Files</strong> – When loading translation files for the plugin interface</li>
</ol>
<h4>What data is transmitted?</h4>
<p>When processing payments, the following data is sent to Payment4 services:</p>
<ul>
<li>Order amount and currency</li>
<li>Order ID and description</li>
<li>Customer email address (optional, for payment notifications)</li>
<li>Return and callback URLs for your website</li>
<li>API credentials (API key) for authentication</li>
</ul>
<p>No sensitive financial information (credit card details, bank accounts, etc.) is transmitted. Cryptocurrency transactions are handled directly on the blockchain.</p>

Payments are processed offsite at mollie.com and the customer will be redirected back to your site after completing the payment.</p>
<p>The plugin requires API keys which can be acquired from the Mollie <a href="https://my.mollie.com/dashboard/settings/profiles" rel="nofollow ugc">account settings at www.mollie.com</a></p>

Payment Gateway using Mollie for Easy Digital Downloads

Dank voor de plugin, en snelle support :)

Top support

I've been using this plugin for a year now with EDD and although the updates aren't that frequent, they aren't necessary either. The plugin still works fine and I haven't had any issues with it since I installed it.

I use this plugin combined with EDD Moneybird, and I've developed a little plugin which acts as glue for all Mollie orders coming in, and marks the invoices as paid automatically in Moneybird. Works great! :)

Edit: After finding out that this plugin severely slowed down my checkout page (loading time 4+ seconds with only 2 payment methods enabled) I have to lower the score for this review. I still like the plugin, the way it is built and how easy it was to develop with it. But the official payment methods plugin are waaayy faster.

Edit #2: Ewout contacted me, and offered a new version of this plugin, which is currently in testing stage. This version resolves the issues I was having. So, I'm reverting my scores to 5 stars! Hopefully this testing version will be released to the public soon!
