Enable/Disable Mollie

Toggle to enable or disable Mollie as a payment method. When enabled, Mollie appears as an option during checkout. Now, you’ll be asked to fill in other information:

configure-mollie-setitngs

  • Title: It’s the name displayed to customers during checkout. You can modify the default title – Mollie, and add any customized title (e.g., “Secure Mollie Payment)
  • Description: This is a brief explanation for customers about the payment method. You can modify or keep the default description as it is.
  • Sandbox: Toggle to enable (for testing) or disable (for live transactions). Transactions processed during Sandbox mode use dummy data and do not charge real money.

API Keys

Test API Key (Required for Sandbox):

  • Obtain this key from your Mollie dashboard under Developers > API Keys.
  • Paste it here when Sandbox is enabled.

Live API Key (Required for Production):

  • Obtain this key from your Mollie dashboard under Developers > API Keys.
  • Paste it here after disabling Sandbox.

Disable Sandbox, if you’re ready with the transaction for real. Click in Save Setting to save all configured Mollie settings.

Step 3: Test and Go Live

To test Mollie payments with automatic status updates, your website must be hosted on a publicly accessible domain (e.g., .com, .me, .net). Mollie checkout flows will not work in local/test environments (e.g., localhost), as Mollie cannot communicate with non-public domains. However, even with publicly accessible domains, you will not have access to Mollie webhooks.

Sandbox Testing:
• Process a test transaction to ensure payments work in dummy mode.
• Verify Mollie’s test card numbers or use the Mollie test dashboard.

Live Transactions:
• Disable Sandbox Mode and enter your Live API Key.
• Ensure your Mollie account is activated for live payments.

Checkout Experience

During the checkout, the interface will look similar to the image below:

checkout-interface-for-mollie

As soon as customer click on Proceed to Mollie, it redirects to Mollie’s Secure Payment Page from where they can enter card details and confirm the transaction.

Mollie then processes the payment and verifies it. You can see the payment status on your dashboard Masteriyo > Orders.
