Checkout Conversion Discounts

One of the most powerful features of this plugin is the ability to offer an instant, automatic discount when customers select Mollie at checkout.

How it works:
When a customer selects LoquiSoft Pay with Mollie as their payment method, the cart automatically recalculates and applies your defined discount (e.g., 5% off or $5 off). If they switch to another payment method, the discount is instantly removed.

Built-in Margin Protection:
We know that accidental pricing can hurt margins. The discount feature includes a mathematical safety net:
1. You set a “Minimum Cart Total” (e.g., $50).
2. The discount will only activate if the cart total is $50 or more.
3. The final discounted price is mathematically blocked from ever dropping below that $50 threshold.

This allows you to aggressively incentivize payments without the risk of accidentally giving away inventory for pennies due to a pricing typo.

External Services

This plugin connects to external services to provide payment processing and configuration functionality.

LoquiSoft Configuration Service

What it is: A secure API endpoint hosted by LoquiSoft used to retrieve the OAuth application credentials required to initiate the Mollie connection flow.

What it is used for:
• Fetching the connection configuration needed to generate a secure Mollie authorization link.

Data sent and when:
• When clicking “Connect with Mollie”: Your server requests connection configuration from the LoquiSoft configuration endpoint in order to initiate the Mollie OAuth onboarding flow.
• When clicking “Connect with Mollie”: Your store initiates a secure OAuth onboarding flow using Mollie Client Links. Store/admin onboarding details such as admin email, first name, last name, store name, store base country, and a return URL are used to create the secure connection session.

Connecting Your Mollie Account

This plugin uses Mollie’s secure OAuth API to connect your store. You do not need to generate or paste API keys manually.

How the Connect flow works: 1. Click the blue Connect with Mollie button in the plugin settings. 2. After you click the button, the plugin requests the connection configuration needed to start the secure OAuth onboarding flow. 3. You are then redirected to Mollie’s official login and authorization page. 4. Log in with your existing Mollie credentials (or create a new account there). 5. Click “Authorize” to grant the plugin permission to process payments on your behalf. 6. You are redirected back to your WooCommerce settings, fully connected.

Note: Your Mollie credentials are never exposed to your browser or stored in plain text on your server. They are encrypted using industry-standard AES-256-CBC encryption.

Setting Up Webhooks

While the plugin dynamically includes webhook URLs in payment requests, it is a best practice to register the webhook in your Mollie dashboard to ensure you never miss an update:

  1. In plugin settings, copy the Webhook URL
  2. Go to your Mollie dashboard
  3. Navigate to Settings > Webhooks
  4. Add a new webhook with the copied URL
  5. Select all payment events

Configuring the Custom Icon

By default, the plugin displays a standard Mollie icon at checkout. To use your own branding: 1. Go to the plugin settings (WooCommerce > Settings > Payments > LoQuiSoft Pay with Mollie) 2. Find the Custom Checkout Icon (URL) field 3. Paste a direct URL to your image (e.g., https://yourstore.com/wp-content/uploads/logo.png) 4. Save changes. The image will automatically resize to match standard WooCommerce checkout dimensions (25px height).

Configuring the Checkout Discount

  1. Go to the plugin settings.
  2. Scroll down to the Checkout Discount section.
  3. Check Enable Checkout Discount.
  4. Choose Percentage (e.g., 5) or Fixed Value (e.g., 5.00).
  5. Set the Minimum Cart Total for Discount (e.g., 50.00).
  6. Save changes. The discount will now automatically appear in the cart totals when Mollie is selected.

FAQ

How do I connect my Mollie account?

Simply go to the plugin settings and click the “Connect with Mollie” button. You will be securely redirected to Mollie to log in and authorize the connection. No manual API keys are required.

What payment methods are supported?

Mollie supports 20+ payment methods including iDEAL, credit cards, PayPal, Bancontact, SOFORT, Klarna, EPS, Giropay, and more. The available methods depend on your Mollie account configuration.

Are there any service fees?

Mollie’s standard transaction fees apply according to your Mollie account pricing. Transactions processed through LoquiSoft Pay with Mollie may include a platform service fee of up to 2.5%, which is automatically calculated and applied through the Mollie Connect integration.

Are there any monthly fees?

No. Neither Mollie nor LoquiSoft monthly fee. Charges are only per transaction and you are not locked into a monthly fee. There are no setup fees or monthly subscriptions required.

Does this plugin handle refunds?

Yes! You can process full or partial refunds directly from the WooCommerce order edit page. The refund is automatically sent to and processed by Mollie.

Does it support WooCommerce Subscriptions?

Yes, the plugin is fully compatible with WooCommerce Subscriptions for recurring payments.

Is my customers’ payment data secure?

Absolutely. All payment processing happens on Mollie’s PCI-compliant servers. No sensitive payment data is ever stored on your website. Connection tokens are encrypted locally using AES-256-CBC.

What currencies are supported?

Mollie supports EUR, USD, GBP, PLN, NOK, SEK, DKK, CHF, and more. Available currencies depend on your Mollie account.

How does the Checkout Discount work?

It uses WooCommerce’s native fee API. When a customer clicks on the Mollie radio button at checkout, an AJAX request recalculates the cart. If the cart meets your minimum threshold, a negative fee (discount) is applied instantly. If they choose another gateway, it disappears.

What is the “Margin Protection” safety net?

If you set a $50 minimum threshold and a 50% discount, a $60 cart would normally drop to $30. The plugin’s safety net catches this: it calculates that $60 minus 50% is $30 (which is below the $50 floor), so it caps the discount at exactly $10, ensuring the customer always pays at least $50.
